B

Question 6

Use the diagram to answer each question. In the diagram, above, marker D is pointing to a __________, which is a landform that forms when a river slows down as it flows into an ocean or lake. As the river slows, it drops its sediment load, gradually creating a network of small channels and islands. a. tributary b. meander c. waterfall d. delta Please select the best answer from the choices provided

Question 7

Question 14

Revolt · Accepted Answer

Groundwater can cause erosion through chemical weathering. First, water that sinks into the ground mixes with carbon dioxide to form carbonic acid, a weak acid. Carbonic acid can break down limestone. Some of the limestone changes chemically and is carried away in a solution of water. This gradually hollows out pockets in the rock. Over time, these pockets develop into large holes underground—caves or caverns.

Question 8

What is the main agent of erosion that has shaped much of Earth’s surface?

Revolt · Accepted Answer

Water is the main agent of erosion.

Question 9
