Layers of the earth

Describe mesosphere

-"middle" -lower part of mantle

What are the layers of the earth?(in order

1.) Crust, mantle, core 2.) Lithosphere, Asthenosphere, mesosphere, outer core, inner core

How is the lithosphere related to the crust?

both outer layer

What are the two types of crusts?

continental and oceanic

In what layer of the earth are the deepest mines and drill holes found?

crust

You are digging through outermost layer of earth. Where are you?

crust or lithosphere

outer core

liquide layer of core -sphere of solid nickel and iron

Which part of earth is broken into tectonic plates?

lithosphere

How do we know about earths layers when we haven't been there?

seismic waves cause by earthquakes

How do continental and oceanic crusts differ? any similarities?

-both made mainly of oxygen, silicon, and aluminum -oceanic is more dense

Describe the Lithosphere

-cool rigid -divided into tectonic plates

inner core

-solid, dense center of earth

Describe Asthenosphere

-solid, plastic layer made of rock -flows slowly and allows tectonic plates to move across

Why haven't we drilled deeper into earth?

our drills aren't powerful enough
