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.

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

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.

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.

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.
