Geology Test 3

1) The process of deposition causes

• rock and soil to slowly be lost.
• rock and soil to quickly be lost.
• rock and soil to slowly be gained.
• rock and soil to quickly be gained.

2) A great deal of the Blue Ridge was eroded. The eroded rock eventually settled in Virginia’s coastal plain. What process caused this?

• deposition
• folding
• subduction
• volcanism

3) A silt fence is shown in the picture. A silt fence operates by intercepting and filtering sediment-laden runoff. It allows the sediment in the water time to settle before the water flows into other areas. The silt fence is also protecting against

• erosion.
• acid rain.
• radiation.
• weathering.

4) What has MOST LIKELY caused a change in the soil in the wheat field shown?

• crystallization
• erosion
• sedimentation
• weathering

5) Which is an example of chemical weathering?

• erosion of land caused by receding glaciers
• the layer of oxide formed on statues made of metal
• deposition of silt along the banks of the Mississippi River
• weathering of rocks in a desert due to the rapid rise and fall of temperatures

6) Plants and lichens are important in both physically and chemically ___________ rocks.

• building
• depositing
• eroding
• weathering

7) A huge, jagged rock sits atop a windy cliffside. Over a period of many years, how will the rock MOST LIKELY change?

• It will become larger and smoother.
• It will become smaller and smoother.
• It will become bigger and less smooth.
• It will become smaller and less smooth.

8) What kind of destructive force or forces will most likely change the way Stone Mountain looks over the next million years?

• volcanoes
• landslides
• erosion and weathering
• earthquakes and faulting

9) What causes a delta to form?

• Deltas form at the mouth of a river when wind deposits sand.
• Deltas form on the bank of a river when a glaciers move past.
• Deltas form at the mouth of a river when water slows down and deposits sediment.
• Deltas form on the banks of a river when water slows down and deposits sediment.

10) How does wind cause weathering?

• Wind can not cause the weathering of rocks.
• Wind can blow sand and create new landforms.
• Wind picks up sand or dry soil and carries it from one place to another.
• Blowing sand can wear away a rock's surface and break it down.
