Name

What are the two types of rock that make up the Earth's crust?

• Granite and basalt
• Iron and nickel
• Sand and clay
• Marble and limestone

What is the name of the process where one plate slides under another?

• Convection
• Subduction
• Divergence
• Erosion

What is the lithosphere made of?

• The crust and the top part of the mantle
• The outer core and the inner core
• The mantle and the asthenosphere
• The crust and the asthenosphere

What is the name of the layer that is constantly moving like a slow-moving river of rock?

• Crust
• Mantle
• Core
• Lithosphere

What happens when tectonic plates collide?

• They create new crust
• They cause earthquakes
• They form mountains
• All of the above

What is the San Andreas Fault an example of?

• A divergent boundary
• A convergent boundary
• A transform boundary
• A subduction zone

What is the difference between the outer core and the inner core?

• The outer core is solid, while the inner core is liquid
• The outer core is liquid, while the inner core is solid
• They are both solid
• They are both liquid

If the Earth's core was not hot, what would likely happen to the mantle?

• The mantle would become solid.
• The mantle would stop moving.
• The mantle would become even hotter.
• The mantle would start to shrink.

What can you conclude about the relationship between tectonic plate movement and the formation of mountains?

• Tectonic plates moving apart create mountains.
• Tectonic plates colliding create mountains.
• Tectonic plates sliding past each other create mountains.
• Tectonic plates have no effect on mountain formation.
