Which of the following describes a process of weathering? A. Mud, silt, sand and pebbles are carried across the region by running water. B. Rocks along the coast are broken up by waves crashing into the shore. C. The wind lays down sediment to form small hills called dunes. D. Glaciers carry boulders from mountaintops to low-lying plains.

## Step 1<br />Weathering refers to the process where rocks, soil, and minerals are broken down into smaller pieces by the action of natural forces such as wind, water, and temperature changes. This process does not involve the movement of these materials, but rather their breakdown in place.<br /><br />## Step 2<br />Looking at the options, we need to identify which one describes a process of weathering.<br /><br />## Step 3<br />Option A describes the process of erosion, where materials are carried away by water. This is not weathering, but rather a form of transportation.<br /><br />## Step 4<br />Option B describes the process of weathering, where rocks are broken down by the action of waves crashing into the shore.<br /><br />## Step 5<br />Option C describes the process of deposition, where wind lays down sediment to form small hills called dunes. This is not weathering, but rather a form of deposition.<br /><br />## Step 6<br />Option D describes the process of glacial erosion, where glaciers carry boulders from mountaintops to low-lying plains. This is not weathering, but rather a form of transportation.
