Plate Motion Chapter 2

What are plates?

• The plates are made of the outer layer of the Earth and they are under the mantle
• There is only one plate on Earth and it is on top of the mantle
• The outer layer of the Earth is made of plates that are on top of the mantle
• The outer layer of the Earth is made of plates and they are under the mantle

How do we know where the plate boundaries are?

• They are shown by lines on a map
• They are shown by lines of earthquakes
• They are shown by lines on the bottom of the sea
• We don't know where the plate boundaries are

What is happening with the plates in this cross section?

• The cross section shows the plates are not moving
• The cross section shows the plates are moving apart (diverging)
• The cross section shows the plates are moving sideways to each other
• The cross section shows the plates are moving together (converging)

If the mantle were solid rock, like in this picture from the SIM, what would the plates do?

• The plates would move faster
• The plates would move slower
• The plates would not move
• There would be no difference

What is the mantle actually like?

• Rock in the mantle is soft and squishy like silly putty
• Rock in the mantle is solid
• Rock in the mantle is liquid
• Rock in the mantle is made of crystals

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)

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

Where are most big earthquakes and volcanoes found?

• Most big earthquakes and volcanoes are found along plate boundaries
• Most big earthquakes and volcanoes are found far away from plate boundaries
• Most big earthquakes and volcanoes are found mostly in the middle of plates
• Most big earthquakes and volcanoes are found on Mars

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

If a plate boundary has a trench, it MUST be a

• convergent plate boundary
• divergent plate boundary
• center of a plate
• sideways moving boundary
