Plate Motion

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.

The Pacific Ocean used to be bigger and the distance between China and North/South American used to be farther away. What could explain this as these places are on different plates?

• The plates floated toward each other making the ocean smaller.

• The plates were pushed toward each other by earthquakes, and one plate went under the other plate into soft solid rock.

• The plates moved toward each other and hit each other breaking into smaller pieces.

• The plates moved slowly toward each other as one plate went under the other plate into soft, solid rock over millions of years.
