• Does erosion break down rocks while weathering carries it to a new location?

• Does weathering lay down the sediment while erosion presses the sediment together?

• Does erosion lay down the sediment while weathering presses the sediment together?

Use the information and picture to answer the following question.

The picture shows how students use a stream table to model how natural processes like weathering, erosion, and deposition change the surface of the Earth. Based on the picture, which process is the student pointing to in the image?

• The water flowing with sand represents erosion.

• The water hitting the sand represents weathering.

• The water cutting into the sand represents channeling.

• The water with sand laying on the bottom represents deposition.

Use the information and model to answer the following question.

A student draws a model to show the growth of a plant in a crack in a rock. What will happen to the rock if the plant continues to grow as it is in the drawing?

• The plant's roots will erode the rock, pulling minerals from the rock and transporting them to the atmosphere. 

• The plant's roots will weather the rock, widening the crack and eventually breaking the rock.

• The rock will absorb new minerals from the plant, transforming into a different type of rock.

• The rock will absorb oxygen from the plant, expanding until it breaks into rock particles.

Use the information and images to answer the following question.

Students in Earth science class were presented with pictures that show how a land formation was created where a river enters an ocean. Which is the BEST explanation to describe what is forming and why is it developing at this site?

• This model shows a delta formed because of the erosion of sediments where the river flows into the ocean.

• This model shows a delta formed because of the deposition of sediments where the river flows into the ocean.

• This model shows the sea level is slowly falling because the precipitation is less than the rate of evaporation.

• This model shows the sea level is slowly rising because the precipitation is greater than the rate of evaporation.

Which question could the scientist ask to BEST confirm that deposition has occurred?

• Did deposition break up the sand by wind creating a new landform?

• Did deposition remove all of the sand creating new a new landform?
