Sediment Processes Quiz

Which of the following processes makes sediments?

• Wind carrying particles of sand from one place to another

• Water and ice breaking rocks into smaller pieces

• Minerals forming crystals beneath the earth’s surface

• Plants using the nutrients in soil for their growth

A table shows the amount of soil lost in two different places for the same year. The information in this data table could be used to support which idea?

• Having vegetation in an area can slow down the amount of soil lost.

• The amount of soil lost in an area is less when there is more rain.

• Vegetation grows better in areas where soil has more minerals.

• The amount of soil lost goes down the same amount every year in all locations.

The rate of erosion in an area would increase if the–

• rainfall decreased.

• amount of vegetation increased.

• wind speed increased.

• slope of the land decreased.

A plant is growing into a rock. The plant will break the rock into smaller pieces as what happens?

• The leaves collect sunlight.

• Insects eat the plant for food.

• The stem of the plant gets taller.

• The roots get longer and thicker.

The first step is ​ (a)   , the breaking down of rocks. The second then is ​ (b)   , the taking away of sediment. ​ (c)   follows, which is the dropping of sediment. ​
