Erosion Deposition Weathering

A scientist is studying geologic formations in deserts. During the study, the scientist draws a diagram of a canyon that has a unique shape. Which of these BEST explains why the canyon has a unique shape?

• The layers of the canyon are composed of different rocks and erode at different rates

• The canyon is located in an area next to a river; the bottom layers experience more erosion than the upper layers

• All layers of the canyon erode at the same time

• The canyon is located in an area that receives heavy rainfall; erosion occurs more quickly due to the constant exposure of water

Which best describes the surface of the earth over billions of years?

• High mountains gradually wear down until most of the earth is at sea level

• High mountains stay side by side for billions of years with little change

• Flat surface is gradually pushed up into higher and higher mountains until the earth is covered with mountains

• High mountains gradually wear down as new mountains are continuously being formed, over and over again

How do plants most commonly break large rocks into smaller pieces?

• Seeds from plants fall onto rocks and release acidic compounds.

• Plant roots grow into cracks in rocks.

• Stems of plants surround and squeeze rocks.

• Plant protects surrounding rocks from extreme temperatures.

Which of the following statements does NOT illustrate the effects of human activity in creating erosion problems?

• Building roads can increase erosion due to the change in drainage patterns.

• Terracing along a mountainside can lead to erosion

• Building on steep slopes can lead to landslides.

• soil can be washed away from new construction sites due to clearing trees and brush

What is the main difference between erosion and weathering?

• Erosion involves movement, while weathering does not

• Weathering involves movement, while erosion does not

• Erosion can only be caused by water, while weathering can be caused by many factors

• There is no difference; they are the same process

What does this mean:The movement of sediments

• erosion

• plate tectonics

• deposition

• weathering
