PLEAS HELP!! Students in an Earth science were presented with a model that shows how stages 1, 2, and 3 in the development of a land formation were created where a river enters an ocean. They were asked to develop an explanation to support the model.

Which student has presented the best explanation to describe what this formation is and why it is developing at this site?

A.

Student 1 explains this model shows an alluvial fan formed because the deposition is less than the rate of erosion.

B.

Student 4 explains this model shows the sea level is slowly rising because the precipitation is greater than the rate of evaporation.

C.

Student 3 explains this model shows the sea level is slowly falling because the precipitation is less than the rate of evaporation.

D.

Student 2 explains this model shows a Delta formed because the rate of deposition is greater than the rate of erosion.
