Plate Motion @Home Lesson 10

Multiple Choice

Earth’s plates are moving, why don’t we update locations of continents on world maps all the time?

• Earth's plates move so SLOW

• Earth's plates move so FAST

Multiple Choice

How can understanding how plates move today help explain how plates moved in the past?

• Plates are still moving now just like in the past

• It does not help to know how plates move today

• Plates move around quickly

Open Ended

How could knowing about past plate motion help explain how the Mesosaurus fossils got separated?

What is one interesting or unanswered question you have about the article? (Be ready to help others answer their question)

Multiple Choice

South America and Africa were once together as one place.   What do you think is the BEST evidence for this?

• Africa and South America look like they could have fit together
• Africa and South America have a plate boundary between them
• Fossils of Mesosaurus (an animal that could not swim across the ocean) are found in both Africa and South America
• They were never together, that's silly, continents can't move

Multiple Choice

Africa and South America are moving farther apart because

• they are on plates that are converging
• they are on plates that are moving sideways to each other
• they are on plates that are diverging
• they are not actually moving at all

Multiple Choice

Where is a trench found?

• A trench is found in the ocean where two plates are diverging (going apart)
• A trench is found in the ocean where two plates are moving sideways to each other
• A trench is found in the ocean where two plates are converging (coming together)
• A trench is found in the ocean far away from a plate boundary

Multiple Choice

What is a mid-ocean ridge?

• A mid-ocean ridge is a place in the ocean where plates are moving together (converging)
• A mid-ocean ridge is a place in the ocean where plates are moving sideways
• A mid-ocean ridge is a place in the ocean where plates are not moving
• A mid-ocean ridge is a place in the ocean where plates are moving apart (diverging)

Multiple Choice

What type of plate boundary is this?

• Divergent

• Convergent

• Transform

Multiple Choice

Multiple Choice

How often or fast something happens.

Multiple Choice

A team of geologists wants to study hard, solid rock under the surface of Earth. The team is considering drilling down in Saudi Arabia (1) or in the Arabian Sea (2). Where will the geologists find hard, solid rock?

• Only in Saudi Arabia (1)

• Only in the Arabian Sea (2)

• neither, because they would find sand in (1) and water in (2)

• Both (1) and (2)
