1 Ever Changing Earth

2 Warm Up 3.3 & 3.4 Read pages EE 10 – EE 11 in your Ever Changing Earth Book. Take notes and be prepared to discuss on Java, Indonesia.

3 Java, Indonesia Facts Location : Southeast Asia
13th largest island in the world, 5th largest in Indonesia Population: 141 million Almost entirely volcanic origin, contains 45 active volcanoes Natural environment: tropical rainforest Highest Elevation: 12,060 feet Most recent eruption: February 14th, 2014

4 Vocabulary Volcano: A vent in the surface of earth through which magma and associated gases and ash erupt Earthquake: a sudden motion or trembling in Earth caused by the abrupt release of slowly accumulated strain Geology: The study of planet Earth: the materials of which it is made, the processes that act on these materials, the products formed, and the history of the planet and all its forms since its origin. Earth structure: a definable shape formed by geologic activity Geologist a person who is trained in and works in any of the geologic sciences.

5 Warm Up 3.5 & 3.6 Read EE 14 & EE 15 on the Hawaiian Islands. Take notes while reading and be prepared to discuss what you learned.

6 Hawaiian Island facts Location: Southwest United States, made up of 8 islands 50th of all the states Natural environment: Tropical Population: million Highest elevation: 13,796 ft Number of volcanos: 12 but there are many others in the ocean Most recent eruption: March 5th, 2011 Home to Mt. Kilauea , the largest volcano on earth which rises 25 miles above sea level

7 Vocabulary Review Topographic map: a map showing the natural and human- made configuration of a land surface, and other features of the land surface, commonly by use of contour lines, colors and symbols Latitude: a north-south measure of a point on earth’s surface relative to the equator Longitude: the east-west position of a point on the earth’s surface, relative to the Prime Meridian

8 Think about the structure of the Earth
Get started: With a partner, you will be assigned one of the geologic events pictured on pages 61 & 62 and answer the following questions on a separate sheet of paper to turn in. What changes occurred in the area you selected? Changes might be large or small. You might notice the size, shape or position of parts of the area may have changed. Describe each of these changes What evidence do you see in the photographs that might indicate earth’s surface is not one continuous piece? ** You and your partner will be graded on your answers so you must be VERY DETAILED!

9 Conference Now meet with other people who observed the same picture as you do. Share what you observed. Take notes on your group discussion on the sheet of paper to be turned in.

10 Warm Up 3.7 & 3.10 Read pages EE16-EE17 on Iceland. Take notes while reading and be prepared to share facts that you learned about Iceland in a discussion!

11 Iceland Facts Location: South of the Arctic Circle, near Europe
Population: 322,000 people Natural Environment: sub polar oceanic, highly volcanic 34 Volcanoes, some active, some inactive Most recent eruption was May 22nd -25th of Grimsvotn

12 2.2 Vocabulary Crust: the outermost layer of earth, composed of rock.
Plates: sheets of rock that include part of Earth’s crust Plate tectonics: the theory that Earth’s crust is divided into a number of plates, and the study of how the plates move and interact with one another Mantle: the zone of earth beneath the crust and above the core. It is divided into the upper mantle and the lower mantle Core: the central part of Earth made of iron and nickel. It consists of a liquid outer core and solid inner core.

13 Earth’s Layers

14 Stop and Think Read Benny’s letter on page EE65 and answer the stop and think questions 1-5 on page EE 66. Answer in complete sentences Finish with reading ‘What’s the point?’

15 Brainstorm Think of a better way to represent the Earth’s structure than Benny’s Egg model. Be descriptive and explain what each layer would be. Write a letter back to Benny describing the earth layers in your model.

16 Warm Up 3.11 & 3.12 Read pages EE 20 & EE 21 on Mount Fuji. Take notes and be prepared to share what you learned in the class discussion.

17 Japan Facts Location: Island nation in East Asia
Population: 126,659,000 people 118 Volcanoes, makes up 10% of the worlds volcanoes Belongs to the Pacific Ring of Fire Most recent explosion: March 11th, 2014

18 Vocabulary 2.4 Composition: The parts, ingredients or elements that form a whole Density: the mass of quantity of a substance per unit volume Seismology: The study of earth quakes and the structure of the earth, using information from seismic waves Seismic wave: a general term for waves produced by earthquakes or artificially through explosions

19 Plate Boundaries the area along the edges of earth’s plates
Some of the most geologically active parts of earth’s surface Most earthquakes, volcanoes, and mountain formations occur near plate boundaries

20 2.4 Vocabulary continued Fault: a fracture (break or crack) through rock, along which the masses of rock on either side of the fracture move Fold: a bend in rocks Fault block mountain: mountains that form when one side of a fault is lifted above the other side

21 Crust Oceanic Continental:
The part of earth’s crust that are under the ocean These parts are the thinnest Density of 3.0 g/cm3 Continental: The part of earth’s crust that form the continents Thicker than oceanic crust Less dense than oceanic crust Density of 2.7 g/cm3


23 Stop and Think Pg 79 Answer the questions on page 79 in your notebook.

24 2.4 Vocabulary Continued Lithosphere: the right outer layer of earth, made of the crust and the solid, uppermost part of the mantle Asthenosphere: a region of earth’s interior immediately below the lithosphere where mantle rocks are hot enough and under enough pressure to deform, change shape, and flow Outer core: the outer layer of earth’s core made of melted, liquid metal. Molten: made liquid by heat Inner core: the inner layer of earth’s core believed to be made of solid iron and nickel

25 Warm Up 3.13 & 3.14 Read Pages EE 26 – EE 27 on Tanzania. Take notes and be prepared to share during a class discussion.

26 Tanzania Facts A country in East Africa Population: 44 million people
Has 9 volcanoes in Tanzania, Mt. Kilamanjaro being the largest March 11, 2008 (Ol Doinyo Lengai) Is a part of the Great African Rift Valley

27 Quiz You have five minutes to study for your quiz on Earth Layers. Sit quietly and study your earth diagram and Reading guide you did last class.

28 Density Lab You will be placed in groups of 4-6 students. Follow all directions for the lab and wear safety goggles while working on the activity. Fill out your density lab worksheet and answer questions 1-6 on the back to be turned in for a class grade. Each member of the group will have one job title. If anyone does not follow these guidelines, they will be asked not to participate. Group Manager Reader Supplies gatherer Safety coordinator Cleanup

29 Warm Up 3.17 & 3.18 Explain why you think the Earth’s plates move and cause geologic activity? Answer in 2-3 COMPLETE sentences.

30 Lab Questions Finish answering questions 1-6 on pages 81 & 82 on your density lab. We will go over these in class. You will be turning in your lab worksheet for class grade so make sure they are complete sentences!

31 Earth Systems Atmosphere: the part of Earth’s system made of the mixture of gases that surround Earth. Biosphere: The part of Earth’s system that includes all living organisms (animals and plants) and also dead and decaying plant matter. Includes parts of the lithosphere, hydrosphere and atmosphere. Hydrosphere: the part of Earth’s system that includes all of the plant’s water, including oceans, lakes, rivers, ground water, ice and water vapor. Geosphere: The part of earth’s system that includes the crust, mantle, and inner and outer core.

32 Cracking Up Read the article ‘Cracking Up’ and answer the questions on the worksheet for a grade.

33 Reminder All late work and retakes must be done by March 26th in order to be considered for a grade for 3rd quarter. Notebook checks will be next week! Make sure everything is glued or taped in!

34 Warm up 3.19 & 3.20 Give one example of something that would be in each of the earth’s systems. Describe how they all interact with one another. Must answer in complete sentences!

35 Cracking Up If you have not finished the ‘Cracking up’ reading and worksheet you have fifteen minutes to do so now. It must be turned in by the end of the class. It counts as a classwork grade.

36 Lab Activity You will work in partners with the person sitting next to you at your desk. You MUST follow the Procedure for this lab on page 93. You will be given a worksheet to fill out while doing this lab. When you have finished cleaning up after the lab answer REFLECT questions 1-3 on page 95. You can answer those questions on the back of the worksheet.
