Weathering, Erosion & Deposition

What is a delta?

• the end of a river where water and sediments are carried into the sea

• movement of rock or soil to a new place by water, wind, or ice

• a large mass of ice

• air the moves and blows

What is ice wedging?

• ice forming in the small spaces in between two rocks causing the rock to break

• a hill of sand in the desert or near water

• a large mass of ice

• when sediment is picked up, carried, and put in a new place

What is carbonation?

• more wet climates will have more weathering

• a physical type of weathering in which rocks rub against one another causing a breakdown of rock

• a type of chemical weathering in which minerals in rocks react with carbon dioxide causing a breakdown of rock

• a type of physical weathering in which water freezes and expands causing cracks that lead to rocks breaking down

Sediment is placed, or deposited, in a new location.

• deposition

• erosion

• weathering

• moraine

Ice wedging, abrasion, and plant root growth are examples of

• deposition

• erosion

• chemical weathering

• mechanical weathering

How does freezing water cause the weathering of rocks? The freezing water—

• Keeps the rocks in place.

• Makes the rocks last longer.

• Expands cracks and breaks rocks.

• Causes rocks to fall in landslides.

An avalanche is an example of which process?

• weathering

• erosion

• deposition

• exfoliation

Which type of area is more likely to weather and erode? An area with a lot of vegetation (plants) or an area with very little? Why?

• The area with very little vegetation, because the roots won't be able to burrow through the rocks to weather it down.

• The area with very little vegetation, because it has not roots to absorb extra water or hold the soil together. The extra water and loose soil is likely to become a landslide/mudslide.

• The area with a lot of vegetation, because the roots will burrow through the rocks causing a landslide.

• The area with a lot of vegetation, because the roots will absorb any extra rain water, and will also hold the soil together preventing a landslide.
