17. Sarah is explaining the thickness of the layers of Earth of Max. She is using the example, “It’s like the eggshell of a boiled egg, compared to the rest of the egg.” Which layer is she explaining?

A. CrustB. MantleC. Outer CoreD. Inner Core

25. Use the diagram to help answer the questions about the layers of Earth

1. Thickest: 2. Densest:3. Thinnest:4. Hottest:5. Solid Metal Ball:

6. Liquid Metal:

7. Melted Rock:

25. Use the diagram to help answer the questions about the layers of Earth

1. Thickest: Mantle

2. Densest: Inner core

3. Thinnest: Crust4. Hottest: Inner Core

5. Solid Metal Ball: Inner Core

6. Liquid Metal: Outer Core

7. Melted Rock: Mantle

26. An animal dies, is buried quickly, and millions of years pass. Explain which type of rock you can find the fossil of the animal & why. Be sure to explain why it can’t be found in the other 2 types of rock.

Remember: 1. Explain which type of rock you can find the fossil of the animal & why.

2. Explain why it can’t be found in the other 2 types of rock.

Fossils are found in Sedimentary rock only because as the plant or animal dies layers of sediment cover and protect it from scavengers. Fossils are not found in Igneous rock because the heat of the lava and/or magma would burn and destroy the plant or animal. Fossils are not found in Metamorphic rock because these rocks are formed deep beneath the Earth’s surface from the processes of extreme heat and pressure

27. Use a Venn Diagram to show & explain the relationship between rocks & minerals
