Nov 20 Warm-up Imagine yourself taking a trip to the center of the Earth. In a paragraph, describe what you would see and feel during your journey.

Nov 2 Warm-up Explain what makes the inner core solid and the outer core liquid.

Earth’s Interior – I will know ways that materials are different from one another. - Compare and contrast the layers of the Earth Oct 20 SC.A DCPS 26

Learning Goal: I will explain the differences between the layers of the Earth.

Earth’s Interior The Earth’s Interior consists of ? layers. CRUST - MANTLE - CORE 3

Earth’s Interior LayerDepthTempDescription Crust3 – 25 miles Up to 230° F Solid rock, covered with land and oceans.

Earth’s Interior LayerDepthTemp Description Crust 3 – 25 miles Up to 230° F Solid rock, covered with land and oceans. 2 types of Crust: * under the land * made of granite rock Continental crust

Earth’s Interior LayerDepthTemp Description Crust 3 – 25 miles Up to 230° F Solid rock, covered with land and oceans. 2 types of Crust: Continental crust * under the land * thick * made of granite rock

Earth’s Interior LayerDepthTempDescription Crust 3 – 25 miles Up to 230° F Solid rock, covered with land and oceans. Oceanic crust * under the ocean * made of basalt rock

Earth’s Interior LayerDepthTempDescription MantleGoes down to 1,800 miles From 230° to 4400° F Made of rock material Lithosphere * top part ( miles) * solid rock * combines with the crust

Earth’s Interior LayerDepthTempDescription MantleGoes down to 1,800 miles From 230° to 4400° F Made of rock material Lithosphere - top part - solid rock - combines with the crust

Earth’s Interior LayerDepthTempDescription MantleGoes down to 1,800 miles From 230° to 4400° F Made of rock material Asthenosphere * below the lithosphere * miles below the Earth’s surface * hot, melted rock (magma)

Earth’s Interior LayerDepthTempDescription CoreGoes down to 3,900 miles 4,400 to 10,000°F Made of metal: nickel and iron. Outer core * 1,800-3,100 miles below Earth’s surface * thick, liquid metal As hot as the sun

Earth’s Interior LayerDepthTempDescription CoreGoes down to 3,900 miles up to 10,000°F Inner core *3, miles below Earth’s surface *solid ball of metal *very high pressure As hot as the sun

3 – 25 miles 25 – 60 miles 60 – 120 miles Asthenosphere Deep Mantle 120 – 1800 miles 1800 – 3100 miles 3100 – 3900 miles Inner core Outer core

Temperature and pressure increase as you travel to the center of the Earth. Important to know !!!

Earth’s Interior Let’s see what we know! Depth Name of Layer Describe this layer 10 miles 50 miles 110 miles 2,500 miles 3,700 miles Crust Hard, solid rock Lithosphere Asthenosphere Outer Core Inner Core Hard, solid rock Hot, melted rock Melted metal Solid metal ball

Let’s compare the Earth’s layers with the layers of an apple.

Nov 21 Warm-up If scientists cannot get deep down inside Earth’s interior, explain how you believe scientists know what the inside of the Earth is like.

How do Scientists know what the inside of the Earth is like?

Direct evidence

Indirect Evidence Scientists use seismic waves – vibrations that travel through the inside of the Earth – to investigate what the inside of the Earth is like.

Geology - the study of the Earth’s interior (inside) and surface.

Geologist - Scientist who studies the Earth’s surface and interior.

1. What is the study of the Earth called? Review 2. What are the scientists who study the Earth’s interior and surface called? 3. How do geologists know what the inside of the Earth is like? 4. How does temperature and pressure change as you travel inside the Earth? 5. How many layers of the Earth are there?

6. What is the top layer of the Earth? Review 7. What are the 2 types of crust? 8. What is the middle layer of the Earth? 9. What is the top part of the mantle? 10. What is the inside layer of the Earth?

Wrap-up Quick Write: Do you believe scientists will ever be able to drill down into the Earth’s core? Justify your answer.
