Erosion
|
|
Wind moves or carries small particles that tear away the rock. This can form an arch or hole in a rock. Wind carries small particles that act like sandpaper to moves away small particles.
|
Water from waves hits on rocks moving small particles out into the water. Water can also rub rocks together breaking them down into smaller and smaller pieces forming sand over a period of time.
|
Gravity causes rock and sediment to move down a slope. Gravity causes water to flow down a slope and into crevices of rocks.
|
Ice, such as from a glacier, move or take small particles of rock or sediment with it as it moves. This erodes the rock or soil.

Deposition
Sits it down. Sediment is left in a new location. It builds up new land forms.
Sand dunes are built when wind or water from waves and currents carry particles of sand and drop them in a new location.
|
River Deltas form at the mouth of a river, where the river flows into another body of water. The new land form is made by the sediment moved by the water.
|
Beaches are formed by water movement that carries particles to the shore.
|
Stalactites & stalagmites form through the deposit of calcium carbonate and other minerals.
