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.

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

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

Earth’s InteriorThe Earth’s Interior consists

of ? layers.

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 InteriorLayer Depth Temp Description

Mantle Goes down to 1,800 miles

From 230° to 4400° F

Made of rock material

Lithosphere * top part (25 - 60 miles)

* solid rock * combines with the crust

Lithosphere - top part

- solid rock - combines with the crust

Mantle Goes down to 1,800 miles

From 230° to 4400° F

Made of rock material

Asthenosphere * below the lithosphere * 60-120 miles below the Earth’s surface

*hot, melted rock (magma)

Earth’s InteriorLayer Depth Temp Description

Core Goes 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 InteriorLayer Depth Temp Description

Core Goes down to 3,900 miles

up to 10,000°F

Inner core *3,100-3900 miles below Earth’s surface

*solid ball of metal *very high pressure

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?
