How do we
know what
the inside of
the earth
looks like?
- We know what
the inside of the
earth looks like
from studying
seismic waves

- Temperature and
pressure increase within
Earth as you go deeper.

- The thin, rocky, outer

- 2 types of Crust
- Ocean Crust
- Continental Crust
- Rocks that make up
the crust are rigid and
brittle

- 2 types of Crust
- Ocean Crust
- Continental Crust
- Rocks that make up
the crust are rigid and
brittle
- The MANTLE is a
thick layer of rock
below the crust.
- Upper mantle - brittle
- Lower mantle - plastic
- Asthenosphere

outer layer of Earth
called the lithosphere.

What is - The dense metallic
the core center of Earth is
made of? called the core
- Made of iron
- 2 layers
- Inner: Solid
- Outer: Liquid
Standard 1.b. Students know Earth is
composed of several layers: a cold, brittle
lithosphere; a hot, convecting mantle; and
a dense, metallic core.
