Plate Motion

Mrs. Laguerre's 7th grade Science Quiz

Multiple Choice

What is the effect of plates moving?

• volcanoes

• earthquakes

• tornadoes

Multiple Select

What is true about the Earth's outer layer?

• it is made of hard, solid rock

• it is made of soft, solid rock

• it is broken in plates

• it is broken in mantle

• it is moving at a slow rate

Multiple Choice

The plates of the Earth moved

• suddenly.

• gradually.

Multiple Select

Which terms describe this plate boundary?

• convergent

• divergent

• mid ocean ridge

• trench

• sinking

Multiple Choice

What patterns can you see on this map?

• Earthquakes happen in similar places.

• Earthquakes and volcanoes happen in similar places on plate boundaries.

• Volcanoes happen in similar places.

• Volcanoes and earthquakes happen in this order: volcano, earthquake, volcano, earthquake, and so on.

Multiple Choice

What happens when two plates are moving toward each other?

• The plates hit each other and break into pieces making sand.

• One plate goes underneath the other plate into the soft rock below.

• The plates push against each other, making the edges bend upward.

• One plate goes underneath the other plate into the ocean below.

Multiple Choice

Where will geologists find hard, solid rock?

• neither under continents or oceans, because there is sand and water under both.

• neither under continents or oceans, because there is water under both places.

• only under the continents, but not under the oceans.

• under both continents and oceans, because Earth's outer layer is made of hard, solid rock.

Multiple Choice

The Lystrosaurus fossils can be found in India and South America, which are parts of different plates. This is a land animal that can not swim. What could explain how these fossils got so far apart?

• The plates slowly moved apart as soft solid rock from underneath got added to the edges of the plates over millions of years.

• The plates floated away from each other.

• The plates slowly moved apart as new plates from underneath got added between them over millions of years.

• The plates were sometimes pushed far apart by earthquakes and soft solid rock from underneath got added to the edges of the plates.

Multiple Choice

If you took a cross section of a dragon fruit by cutting it vertically, what would the cross section look like?

Multiple Choice

What happens when two plates move apart?

• a new plate from underneath fills in the gap created by the plates moving apart

• sand and dirt fill in the gap created by the plates moving apart

• water fills in the gap created by the plates moving apart

• soft, solid rock from underneath the plates rises up and hardens, adding solid rock to the edges of both plates.

Multiple Choice
