Weathering, Erosion & Deposition

The process of deposition causes

• rock and soil to slowly be gained.

• rock and soil to slowly be lost.

• rock and soil to quickly be gained.

• rock and soil to quickly be lost.

• folding

• deposition

• volcanism

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

• weathering

• radiation

What causes a delta to form?

• Deltas form at the mouth of a river when wind deposits sand.

• Deltas form at the mouth of a river when water slows down and deposits sediment.

• Deltas form at the on the bank of a river when a glaciers move past.

• Deltas form on the banks of a river when water slows down and deposits sediment.

How does wind cause weathering?

• Wind can not cause the weathering of rocks

• Wind picks up sand or dry soil and carries it from one place to another.

• Wind can blow sand and create new landforms..

• Blowing sand can wear away a rock's surface and break it into smaller pieces.
