Unit 5 Test Review

When overlaying rocks are removed from granite that formed deep beneath Earth’s surface and the pressure decreases, what causes the granite to crack into large, curved sheets?

• joints

• gullies

• valleys

• exfoliation

Deltas sometimes form where rivers meet large bodies of water. What role does the movement of the water have on the formation of deltas?

• Sediment falls out of water when a fast-moving river slows down after it meets a large body of water.

• Sediment falls out of water when a slow-moving river speeds up after it meets a large body of water.

• Sediments are picked up where a river meets a large body of water and are carried away.

• Sediments are carried by fast-moving water far into a large body of water.

• exfoliation

• abrasion

• ice-wedging

• crackling

What are ice, plants and animals, gravity, running water, and wind common agents of?

• exfoliation

• carbonation

• chemical weathering

• mechanical weathering

Which of these statements holds true for the coarseness of sediment?

• The depositional environment changes.

• The farther sediment travels from its source, the coarser the grains become.

• The farther sediment travels from its source, the smoother the grains become.

• The number of sedimentary rock features increases as the sediment is carried farther from its source.

What is the primary interaction between water and limestone that results in caves and sinkholes?

• Acidic water dissolves limestone.

• Moving water physically weathers limestone.

• Water freezes and breaks limestone apart as it does.

• Plants using the water grow and break apart limestone as their roots grow.

Why does a river carrying abundant sediment form a delta as it enters an ocean?

• The longshore currents move the sediment into a fan shape.

• Tides spread sediment into a delta shape as they exit the river.

• The river slows down and cannot carry the sediments much farther.

• The river cuts into the bedrock causing a fan shape to develop in the rocks.

As land with a river running across it is uplifted, how does the river’s interaction with the landscape change?

• The river cuts into the rocks at a faster rate.

• The river slows the rate at which it cuts into rocks.

• The river builds a delta before reaching base level.

• The river starts to meander across valleys at a faster rate.

How does a river’s speed affect its erosive ability?

• Slower rivers erode the river channel more quickly than faster rivers.

• Faster rivers erode the river channel more quickly than slower rivers.

• Slower rivers carry more stream load and are more erosive.

• Faster rivers carry less stream load and are less erosive.

• galactic drift

• glacial drift

• continental drift
