What is the difference between magma and lava?

• Magma only erupts in the ocean and lava only erupts on land.

• Lava is a solid material and magma is a liquid material.

• Magma is found below Earth's surface and lava is found above Earth's surface.

Tectonic plates are made of continental crust, oceanic crust or a combination of the two. Besides their locations, how else are these two kinds of crust different?

• Continental crust is thicker than oceanic plates.

• Continental crust is thinner than oceanic plates.

• Tectonic plates made of continental crust are larger than plates made of oceanic crust.

Volcanic eruptions can have many characteristics. They can be slow, fast, calm, explosive or a combination of these. Which type of eruption is associated with the release of pyroclastic materials?

• a fast eruption

• a slow eruption

• an explosive eruption

What happens at a divergent tectonic plate boundary?

• Two tectonic plates collide causing subduction.

• Two tectonic plates pull away from each other, forming a rift valley or mid-ocean ridge.

• Two tectonic plates move horizontally past one another.

Which of the following is a major difference between Earth's inner core and Earth's outer core?

• the inner core is solid and the outer core is liquid

• the inner core is solid and the outer core is gas

• the inner core is liquid and the outer core is solid
