Valley is a low area of land between hills or mountains. Valleys often have rivers or streams running through them. The land in a valley can be flat or gently sloped. Valleys may be wide or narrow depending on how they formed.

Valleys are found all over the world, including river valleys in Africa, Asia, and Europe. They formed over long periods of Earth’s history. Valleys support many plants and animals. People often build homes, farms, and towns in valleys because of water and land access.
