Your warm up Is at your desk Warm up
3
What do you think we are studying today?
4
How many? Earth has _______________layers. They are : 1. 2. 3. 4.
5
On a sheet of paper, measure the middle on the short side and place a mark where the middle is Use your ruler to draw a straight line from the middle mark to the opposite upper corner of the paper Use your ruler to draw a straight line from the middle mark to the opposite lower corner of the paper You should now have a large triangle on your paper. Make a model of the layers
6
Obtain a computer Go to my website Click on lithosphere unit, click on lithosphere ppt 1. Rubric and information
7
1. Put your name on the back of the paper 2. Use a calculator to determine the depth in cm each layer should be on your slice of Earth. Use the table on the next slide. 3. Use a ruler to mark off the location of each layer on your slice 4. Label each layer: mark the location of the lithosphere and asthenosphere, and the location of convection currents in the mantle 5. Include: thickness of each layer, composition of each layer, state of matter, density of each layer on your model 6. For crust, make sure to include BOTH types of crust, thicknesses of both, composition of both, and density of both 7. On the back, include a short description of each layer and include one unique thing about each layer Rubric

9
The Crust The crust is only 3-5 miles (8 km) thick under oceans and 25 miles (32 km) thick under continents.
10
The Lithospheric Plates The crust of the Earth is broken into many pieces called plates. The plates "float" on the soft, semi- rigid asthenosphere.
11
The Lithosphere The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere.
12
The Crust The crust is composed of two rocks. The continental crust is mostly granite. The oceanic crust is basalt. Basalt is much denser than the granite. Because of this the less dense continents ride on the denser oceanic plates.
13
The Mantle The Mantle is the largest layer of the Earth (2,900 kilometers (1,802 miles) ). The middle mantle is composed of very hot dense rock that flows like asphalt under a heavy weight. The movement of the middle mantle (asthenosphere) is the reason that the crustal plates of the Earth move.
14
The Asthenosphere The asthenosphere is the semi-rigid part of the middle mantle that flows like hot asphalt under a heavy weight.
15
Convection Currents The middle mantle "flows" because of convection currents. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling and sinking again --repeating this cycle over and over.
16
The Outer Core The core of the Earth is like a ball of very hot metals. The outer core is so hot that the metals in it are all in the liquid state. The outer core is composed of the melted metals of nickel and iron. The circulation of the outer core is thought to cause Earth’s magnetic field.
17
The Inner Core The inner core of the Earth has temperatures and pressures so great that the metals are squeezed together and are not able to move about like a liquid, but are forced to vibrate in place like a solid.

EEn.2.1.1 Explain the rock cycle in enough detail to relate the cycling of materials - formation and destruction of the three major rock types to the forces responsible: physical and chemical weathering, heat and pressure, deposition, foliation and bedding. The forms of energy that drive the rock cycle include heat and mechanical (gravitational potential) energy NC Standard
22
The Rock Cycle
23
HOW ROCKS RECYCLE ? The rock cycle is a general model that describes how various geological processes create, modify, and influence rocks The origin of all rocks can be ultimately traced back to the solidification of molten magma Magma consists of a partially melted mixture of elements and compounds commonly found in rocks Magma exists just beneath the solid crust of the Earth in an interior zone, the mantle The Rock Cycle shows how rocks of any rock class can be recycled into rocks of any other rock class.
24
Stages in the Rock Cycle All rock types physically and chemically decomposed by a variety of surface processes collectively known as weathering The debris thus created often transported by erosional processes via streams, glaciers, wind, and gravity When this debris is deposited as permanent sediment, the processes of burial, compression, and chemical alteration over long periods of time produce sedimentary rocks Geologic processes like tectonic folding and faulting exert heat and pressure on both igneous and sedimentary rocks, altering them physically or chemically – rocks modified in this way are termed metamorphic rocks Any of the rock types can eventually be returned to Earth's interior by tectonic forces at areas known as subduction zones Once in Earth's interior, extreme pressures and temperatures melt the rock back into magma to begin the rock cycle again
25
Rock Classification Igneous Rocks form due to the cooling and crystallization of magma Sedimentary Rocks form through lithification of sediments from other rocks Metamorphic Rocks form via recrystallization of other rocks due to heat, pressure, and chemical alteration
26
When we melt rocks and cool rocks we get?
27
IGNEOUS ROCKS VS
28
IGNEOUS ROCKS Texture What determines the different textures of igneous rocks? Mythbusters-which one is true?: 1. texture is determined by the minerals that make up the rock 2. texture is determined by whether the rock cooled underground or above ground (cooling rates) 3. texture is determined by the density of the rock
29
Intrusive= large grains, cooled slowly Extrusive=small grains, cooled fast Texture
30
VS
31
Igneous Rocks
32
What do you get if you: 1. weather igneous, metamorphic, or sedimentary rocks 2. transport them somewhere else 3. deposit them 4. squash them 5. cement them together?
33
Sedimentary rocks- There are 3 types: Where do you think these formed and out of what materials did they form? 1. 2. 3.
34
Subclasses of Sedimentary Rocks: 1. Clastic: form from bits and pieces of other rocks 1. Chemical: consist of minerals deposited from a solution 1. Organic: consist of organic matter such as plants and animal remains SEDIMENTARY ROCKS
35
Most sedimentary rocks are formed of layers of materials that have washed into lakes, rivers and oceans – Sedimentary rocks form strata Often layers are tilted by earth movements Sedimentary rocks contain fossils How do sediments turn into hard rock? Through Lithification Processes: Compaction Cementation Crystallization
36
Sedimentary Rocks
37
What do you get if you add heat and pressure to igneous, sedimentary or metamorphic rocks?

The Rock Cycle
48
Explain how various mechanisms (mantle convection, ridge push, gravity pull) drive movement of the lithospheric plates. Infer the relationship between the type of plate boundary and the locations of various features such as ocean trenches, mountain ranges and mid-ocean ridges. (Relate to the development of the theory of plate tectonics and geologic time.) NC standard
49
Alfred Wegener-1915 Developed the idea of continental drift which inspired plate tectonics Noticed continents seemed to fit together like a puzzle He also cited other evidence including: ancient climate similarities fossil evidence (such as the fern Glossopteris and mesosaurus) and similarity of rock structures. History-the development of the Theory
50
Supercontinents have existed several times in history Time frame Supercontinent nameAge (Ma: millions of years ago) UrUr (Vaalbara)Vaalbara~3,600–2,800 Kenorland~2,700–2,100 Protopangea-Paleopangea~ 2,700-2,600 Columbia (Nuna)~1,800–1,500 Rodinia~1,250–750 Pannotia~600 Pangaea~300

The Earth’s crust and upper mantle are broken into sections called plates Plates move around on top of the mantle like rafts What is Plate Tectonics?
69
What is the Lithosphere? The crust and part of the upper mantle = lithosphere 100 km thick Less dense than the material below it so it “floats”
70
What is the Asthenoshere? The plastic layer below the lithosphere = asthenosphere The plates of the lithosphere float on the asthenosphere
72
2 Types of Plates Ocean plates - plates below the oceans- dense and made mostly of basalt Continental plates - plates below the continents- less dense and made mostly of granite

85
Convergent Boundaries Boundaries between two plates that are colliding There are 3 types…
86
Type 1 Ocean plate colliding with a less dense continental plate Subduction Zone: where the plate with the higher density slides under the less dense plate Composite VOLCANOES (volcanic arc) occur at subduction zones Trench
87
Convergent Boundaries: 1.Subduction is… … the process of one plate going under another. The process of subduction creates a deep-sea trench. 2.The underground edge of the subducting plate melts because… it is pulled deep into Earth’s crust. Melted crust rises to form a volcanic island arc or volcanic mountain range.
89
Andes Mountains, South America
90
Type 2 Ocean plate colliding with another ocean plate The older, more dense plate slides under the younger, less dense plate Deep ocean trench Volcanic island arc Earthquakes that can cause tsunamis
92
Aleutian Islands, Alaska
93
Type 3 A continental plate colliding with another continental plate Have Collision Zones: a place where folded and thrust faulted mountains form. No subduction occurs Example: Appalachian mtns
96
Transform Fault Boundaries Boundary between two plates that are sliding past each other Strong EARTHQUAKES along faults

3. compare and contrast magnitude and intensity for measuring earthquakes. Use a venn diagram from classroomtools.net. Take a screen shot of your diagram and mail it to Mrs. Chapel. Notes cont.
108
3. Shear stress causes rocks to slide past each other resulting in strike-slip faults 2. Compression squeezes rock together resulting in reverse faults 1.Tension pulls rocks apart resulting in normal faults Fault Types ( Credit: U.S. Geological Survey Department of the Interior/USGS) Fault surfaces are surfaces along which rocks move under, over, or past each other. There are 3 types of stresses that cause 3 types of faults. 108 Standard 8-3.8 Table of Contents
109
Faults caused by blocks of crust pulling apart under the forces of tension are called normal faults. Entire mountain ranges can form through these processes and are known as fault block mountains (examples: Basin and Range Province, Tetons). In a normal fault, the hanging-wall block moves down relative to the foot-wall block. The footwall is the underlying surface of an inclined fault plane. The hanging wall is the overlying surface of an inclined fault plane. Faults: Normal Faults Hanging Wall Footwall Relative movement of two blocks indicating a normal fault. ( Credit: Modified after U.S. Geological Survey Department of the Interior/USGS) Diagrammatic sketch of the two types of blocks used in identifying normal faults. Hanging Wall Foot Wall Footwall block Hanging wall block 109 Table of Contents
110
Faults caused by blocks of crust colliding under the forces of compression are called reverse faults. Reverse faults are a prevalent feature in continent-continent collisions. Usually, there is also accompanying folding of rocks. During reverse faulting, the hanging wall block moves upward (and over) relative to the footwall block. Faults: Reverse Faults Hanging Wall Foot Wall Footwall block Hanging wall block Relative movement of two blocks indicating a reverse fault. ( Credit: U.S. Geological Survey Department of the Interior/USGS) Diagrammatic sketch of the two types of blocks used in identifying reverse faults. Hanging Wall Footwall 110 Table of Contents
111
In the example above, the fence has been offset to the right, therefore it is called a right lateral strike-slip fault. ( Credit: U.S. Geological Survey Department of the Interior/USGS) Strike-slip faults occur when two blocks move in horizontal but opposite directions of each other. Depending on the direction of offset, it can be a “right-lateral offset” or a “left-lateral offset.” The photograph above displays a light- colored pegmatite vein offset to the right in a schistose matrix.

112
Earthquakes : The Focus and Epicenter of an Earthquake The point within Earth where faulting begins is the focus, or hypocenter The point directly above the focus on the surface is the epicenter
113
What are Seismic Waves? Response of material to the arrival of energy fronts released by rupture Two types: Body waves P and S Surface waves R and L
114
Body Waves: P and S waves Body waves P or primary waves fastest waves travel through solids, liquids, or gases compressional wave, material movement is in the same direction as wave movement S or secondary waves slower than P waves travel through solids only shear waves - move material perpendicular to wave movement
115
Surface Waves: R and L waves Surface Waves Travel just below or along the ground’s surface Slower than body waves; rolling and side-to-side movement Especially damaging to buildings
116
How many stations do you need to locate the epicenter of an earthquake? Which waves arrive first?: p waves or s waves. What kind of fault is located at a divergent boundary? Closure

118
Describe the anatomy of an earthquake. Locate earthquakes – epicenter and focal point – and relate to different types of plate boundaries. Explain how the release of energy of various types of earthquakes relates to magnitude, and P and S waves NC state standard
119
How is an Earthquake’s Epicenter Located? Seismic wave behavior P waves arrive first, then S waves, then L and R Average speeds for all these waves is known After an earthquake, the difference in arrival times at a seismograph station can be used to calculate the distance from the seismograph to the epicenter.
120
How is an Earthquake’s Epicenter Located? Three seismograph stations are needed to locate the epicenter of an earthquake A circle where the radius equals the distance to the epicenter is drawn The intersection of the circles locates the epicenter
121
How are the Size and Strength of an Earthquake Measured? Modified Mercalli Intensity Map –1994 Northridge, CA earthquake, magnitude 6.7 Intensity subjective measure of the kind of damage done and people’s reactions to it isoseismal lines identify areas of equal intensity
122
How are the Size and Strength of an Earthquake Measured? Magnitude Richter scale measures total amount of energy released by an earthquake; independent of intensity Amplitude of the largest wave produced by an event is corrected for distance and assigned a value on an open-ended logarithmic scale
123
What are the Destructive Effects of Earthquakes? Ground Shaking amplitude, duration, and damage increases in poorly consolidated rocks
124

126
Causes of Plate Tectonics
127
Convection Currents Hot magma in the Earth moves toward the surface, cools, then sinks again. Creates convection currents beneath the plates that cause the plates to move.
128
Causes of Plate Movements… Definitions… c. Convection – transfer of thermal energy by the movement of heated matter d. Convection current – pattern of motion produced by warmer matter moving up and cooler matter sinking http://library.thinkquest.org/C003124/images/convect.jpg
129
Causes of Plate Movements… 3. The tectonic plates move by… a.… The rising part of the convection current spreads out as it reaches the upper mantle which lifts and splits the lithosphere at divergent plate boundaries. b.… The downward part of the convection current creates a sinking force that pulls tectonic plates downward at convergent boundaries.
130
Causes of Plate Movements… 3. The tectonic plates move by… c. … Ridge push - the force created by the weight of the uplifted ridge which pushes an oceanic plate towards a trench. (at a subduction zone) d. … Slab pull - process in which the weight of the subducting plate helps pull the trailing lithosphere into the subduction zone.
