BIG QUESTIONS How do Geologists Learn about Earths interior?? What are the features of Earths Crust, Mantle, and Core??
Direct: from Rock Samples Drills km Volcanoes- 100 km Labs- recreated layers and force Indirect: from Seismic Waves Produced by earthquakes Study how they travel through Earths interior
Solid Rock that includes both dry land and the ocean floor Ocean Crust: Basalt Continental Crust: Granite
Lithosphere Uppermost part of Mantle Similar to crust in composition and texture Asthenosphere Below lithosphere Higher pressure Bends but doesnt break
Inner Core Dense ball of solid metal Extreme temp. and pressure Outer Core Molten metal surrounding inner core
BIG QUESTIONS Try Them Now! How do Geologists Learn about Earths interior?? What are the features of Earths Crust, Mantle, and Core??
Inside the Earth. Composition (What it is made of) Crust Mantle Core.
What are the three Chemical layers of the Earth? Crust, mantle, core Each of these 3 layers is COMPOSED of same types of CHEMICALS Crust- Silica, Oxygen.
Structure of the Earth. Earth’s Compositional Layers.
1.Which branch of Earth Science would study earthquakes? 2.Which branch of Earth Science would study hurricanes? 3.Which branch of Earth Science would.
Earth’s Layered Structure Section 8.4. Earth’s layered structure Most knowledge of the interior of the Earth comes from the study of earthquake waves.
Inner Core – the dense, solid center of the earth, formed mostly of iron and nickel Outer core – the liquid layer of the earth’s core that surrounds.
Earth’s Interior. The Geosphere: the solid Earth – 3 Main Layers Crust Mantle Core.
1 How many layers of the Earth are there? The part of the Earth that consists of molten metal.
Inside Earth Crust What is the outermost layer of the Earth?
What Are Earths Layers Unit D, Chapter 1, Lesson 1, pD6-11.
Inside Earth A journey to the center of Earth. Key Terms seismic waves pressure crust basalt granite mantle lithosphere asthenosphere outer core inner.
Chapter 9 and 10 The interior of the earth and its surface.
Changes to Earth’s Surface Chapter 6. Prior Knowledge What are the layers of the Earth? What are the layers of the Earth? What causes Earth’s surface.

Warm Up – Page 78 Answer this on page 78 in your notebook: Mrs. Wilson, I still dont get _________________. Could you explain it again?
Earths Interior Evidence. 1. Density of the Earth The strength of the gravitational pull of the Earth gives scientists a pretty good idea about the average.
6 Chapter 6 Earthquakes and Earth s Interior. Earthquakes 6.1 What Is an Earthquake? Focus is the point within Earth where the earthquake starts. Epicenter.
The unconformable contact of Old Red Sandstone on vertical Silurian rocks noted by James Hutton, who in 1788 first recognized the significance of its meaning.
Earths interior layers. The major layers of the Earth consist of the crust, mantle, outer core and inner core.
Basic Structure of the Earth. How do we know what is inside the Earth? Based on the speed and path of seismic waves as they travel through the Earth.

EARTHQUAKES. What are Earthquakes? The shaking or trembling of the earth/ground caused by the sudden release of energy Usually associated with faulting.
How Do Natural Forces Change & Shape Our Planet?.
BIG QUESTIONS What are the main parts of the Earths System? How do Constructive and Destructive Forces change Earth?
CH 8 Earthquakes Produced by the rapid release of elastic energy in rock causing vibrations Elastic Rebound Theory = the rock springs back into it original.
Plate Tectonics. Brief Structure of the Earth Divided into layers: –Core, mantle, crust.
