How Water Shapes the Earth

The Earth is always changing. Some changes happen quickly, but some changes take place slowly over time.

Water shapes the Earth slowly. It wears away rocks and soil to other places.

Rivers and streams flow over land.

The Colorado River carved the Grand Canyon about 5 million years ago.

Moving water is very powerful.

Ocean waves crash into the land over and over again.

This shapes the coastline and makes cliffs.

Also, a waterfall forms where a river or stream flows quickly over a high ledge of hard rock.

Waterfalls move rock and soil into a pool below.

Glaciers are large pieces of frozen water that move slowly over the land.

They drag pieces of rock and soil along with them as they move.

They can change the shapes of mountains and the land around them.

Water changes the land quickly during natural disasters such as floods, hurricanes, and tsunamis.

Floods destroy farmland by washing away the topsoil that helps plants grow.

Hurricanes and tsunamis can ruin coastal cities and landforms.
