(U4-L5) Quiz Earth Science

What is sediment?

• the process of rocks being broken down and carried away
• bits of rock, sand, and silt caused by the weathering of rocks
• the top layer of the soil
• decaying plant or animal material 

Rain washing away soil from a hillside causes

• Weathering

• Erosion

• Deposition

How do plants in the soil affect how fast erosion happens?

• It doesn't affect erosion.

• It slows down erosion.

• It speeds up erosion.

The diagrams  shows a natural process that weathers rock.
 Which statement best explains why this process results in weathering?

• frozen water acts as a solute
• water expands when it freezes
• the mass of water increases when it freezes
• frozen water dissolves most types of rock

The diagram below shows a section of a meander in a stream. The arrow shows the direction of stream flow. The stream bank on the outside of this meander is steeper than than the stream bank on the inside of this meander because the water on the outside of the meander is moving

• Slower, causing deposition
• Faster, causing deposition
• Slower, causing erosion
• Faster, causing erosion

The process when rocks break into smaller pieces due to exposure to natural elements is called

• erosion
• weathering
• sediments

Deposition is

• When slowing water lays down sediments to form beds

• Squeezing of sediment grains together by the weight of sediments above

• Precipitation of minerals that "glue" the sediment grains together

• When tectonic plate movement raises buried rocks up to the surface
