Defining valleys is crucial in geography, providing insights into landscapes and ecosystems. Valleys can be classified into two primary types: closed and open.
Closed Valleys

Closed valleys, also known as endorheic basins, are unique geological formations with no outlets to external drainage systems. Water accumulates within the valley, creating enclosed water bodies like lakes or playas. These valleys often form in arid or semi-arid regions where evaporation rates exceed precipitation.
Examples and Impacts:
The Great Basin in the western United States is a prominent example of a closed valley system. Closed valleys play a vital role in local water cycles and can support unique ecosystems adapted to arid environments.
Open Valleys

In contrast, open valleys have an outlet connecting them to a larger drainage system, such as a river or ocean. Water flows freely through these valleys, forming rivers and streams that transport water and sediment downstream.
Formation and Importance:
Open valleys are typically formed by erosion processes caused by flowing water. They provide important pathways for water movement, shaping landscapes and supporting riparian ecosystems.
History and Myth of Closed Vs Open Valleys
