Wind Erosion — Reading Comprehension

The wind is a powerful force of nature that can move many things, including sand. When the wind blows, it can lift tiny grains of sand off the ground and carry them through the air. This process is an important part of how the Earth's surface changes over time.

The movement of sand by wind is called erosion. Erosion happens when wind, water, or ice wears away rocks and soil. In dry places like deserts or beaches, wind erosion is very common.

When the wind picks up sand, the grains bounce and roll along the ground. This is known as saltation. Some sand grains might be lifted higher and travel farther before landing. As the wind slows down, it drops the sand it was carrying. This dropping of sand is called deposition.

Over time, deposition can create new landforms. One example is a sand dune. A sand dune is a hill of sand built up by the wind. Dunes can move slowly as the wind continues to push sand from one side to the other.

Wind erosion and deposition can also change landscapes. For example, in the Sahara Desert, strong winds shape huge dunes that can be as tall as buildings. On beaches, wind can pile sand into ridges and mounds, protecting the land behind them from ocean waves.

These processes are important because they help shape the land where plants and animals live. Understanding how wind moves sand helps scientists predict changes in deserts, beaches, and even farmland.

Interesting Fact: Some sand dunes can "sing" or make strange noises when the sand moves, creating a humming or booming sound!
