What are the 3 layers seen here?

 

• thin crust

  thick mantle

  middle core

• surface

  middle

  inside

There are more mechanical layers than compostitional layers.

• true

• false

What do the arrows in the mesosphere at this point in the video represent?

• intense pressure

• intense heat 

Why is the inner core solid, while the outer core is liquid?

• even though temps are high enough in both cores, the pressure on the inner core counteracts the heat, and keeps the inner core solidified

• heat and pressure melt all the metals and both are liquid

Pangaea is a Greek term meaning,

Make a prediction, what's going to happen to that red, hot rock called magma?

• rises up and makes a volcano

• cools off and makes earthquakes

• sinks deeper toward the core 

Why are the Himalayas growing taller every year?
