thicker
and less dense than oceanic crust.
True
False
Question 2
2.
Where does the energy for mantle convections come from?
The Core
The Lithosphere
The sun
Question 3
3.
How do pressure and temperature change inside Earth as depth increases?
pressure increases; temperature decreases
pressure decreases; temperature increases
pressure and temperature increases
pressure and temperature decrease
Question 4
4.
What is one result of movement in earth's outer core?
earth's force of gravity
melted glaciers
erosion
Earth's magnetic field
Question 5
5.
What is the Earth's inner core primarily made of?
Water
Silicates
Rock
metal
Question 6
6.
Which layer is responsible for tectonic plate movement?
Core
Crust
Asthenosphere
Lithosphere
Question 7
7.
What conditions allow rock in the asthenosphere to flow?
Cooler denser rock sinks to the bottom of the layer and hotter less dense rocks move to the top
Cooler denser rock rises to the top of the layer and hotter less dense sink to the bottom
The pressure from the core causes the rocks to move in the asthenosphere
Rocks do not move
