Deserts are large land surfaces covered in sands and stones. The formation of deserts takes place by the weathering processes. The formation of Sierra Nevada is because the lithosphere influences the atmosphere and biosphere.
The weathering process is defined as the breakdown of rocks or minerals into the Earth's surface. The lithosphere influences the atmosphere and biosphere to form the Sierra Nevada desert.
The following steps are:
- The atmosphere brings the rain via wind, which eventually falls on the land surface and outer rocky surface of Earth (lithosphere).
- The mountains are tall and heightened structures, which can block the incoming wind with water vapors.
- Thus, due to the lack of appropriate rains by mountains, the formation of the desert will take place.
Therefore, the Sierra Nevada mountains block the winds that eventually lead to the formation of the desert. The lithosphere influences the biosphere and atmosphere.
