How is the Earth Changing? Pre-test

The solid rock of the cliff in this photograph is part of a continent. What is the relationship between the continent and Earth’s plates?

• The continent is part of a plate.

• The continent is next to but is not part of a plate.

• The continent is on top of a layer of water that is above a plate.

• The continent is directly on top of a plate but is not part of the plate.

If scientists discovered a new planet very much like Earth, where would you predict that planet would have the greatest concentration of volcanoes?

• On its tectonic plates

• In its oceans

• On the edges of its continents in higher elevations

• In the middle of its continents

When two plates press together and a mountain begins to form, which of the following happens?

• The plate slowly begins to bend because even though the plate material is hard it can still be bent and folded over a very long period of time.

• Because plates cannot bend, the plate materials from one plate breaks off into small pieces of rock that are about the size of tennis balls/

• Because plates cannot bend, the plate material from one plate breaks off into large pieces of rock that are about the size of huge boulders.

• Because plates cannot bend, the plate material from one plate breaks off into massive blocks of rock that are about the size of large house.

Based on the diagram below, which letter indicates a place where new plate material is forming?

• At the boundary of the continent and ocean basin.

• In the middle of the ocean basin.

• At the boundary where the two plates are pulling apart.

• No new plate material is forming anywhere shown in the diagram.

Two of Earth’s plates pressed together for many millions of years. What happened if they pressed together in a place where oceanic plate material meets continental plate material?

• The continental plate material was pushed downward.

• The oceanic plate material was pushed downward.

• The plates were not able to move while they were pressing together and no plate material was pushed upward.

• The edges of the plates were not pushed upward but they were broken into small pieces.

Use the diagram below to answer the following question: What plate motion is happening at point A?

• A convergent boundary where two plates collide.

• A divergent boundary where two plates pull apart.

• A transform boundary where two plates slide past each other.

• Not enough information is given to be able to identify the plate motion.
