Continental and Oceanic Crust Lesson with Questions

How is continental crust different from oceanic crust?

• Continental crust is more dense and lighter.

• Continental crust is thicker and more likely to sink.

• Continental crust is thicker and more likely to sink.

• Oceanic crust is thicker and more dense.

How is continental crust different from oceanic crust?

• Continental crust is more dense and contains a lot of basalt.

• Continental crust is thinner and younger.

• Oceanic crust is thinner and younger.

• Oceanic crust is thicker and contains a lot of granite.

Where do subduction zones often occur?

• where a continental plate is being split into two parts

• where an oceanic plate is moving toward a continental plate

• where two oceanic plates are moving away from each other

• where two continental plates are colliding

Which statement describes what is happening at the plate boundary?

• The seafloor is spreading.

• An oceanic plate is subducting.

Which phrase is the best description of a convergent boundary?

• plates that are attracted to each other by gravity

• plates that move away from each other

• plates that move toward each other

• plates that move side by side past each other

What happens at a convergent boundary?

• Magnetism occurs as lithospheric plates are attracted toward each other by gravity.

• Earthquakes occur as lithospheric plates move away from each other.

• Collisions occur as lithospheric plates move toward each other.

• Mountains form as lithospheric plates move side by side past each other.

• create new plates

• collide

• scrape past each other

• move apart

What happens when two continental plates meet at a convergent boundary according to plate tectonics?

• They push against each other to form deep-ocean trenches.

• They push against each other to form folded mountain ranges.

• One slides under the other to form magma.

• One slides under the other to form new mantle.

How can mountain formation be described according to the theory of plate tectonics?

• As a continental plate and an oceanic plate come together at a divergent boundary, mountains are formed.

• As two continental plates collide along a convergent boundary, mountains are formed.

• As two continental plates move past each other at a transform boundary, mountains are formed.

• As any two plates meet at a fault line boundary, mountains are formed.
