What are two geographical factors that promote the development of deserts?

Two geographical factors that promote the development of deserts are:

1. Rainfall Patterns: Deserts are commonly found in regions with minimal precipitation. When an area receives limited rainfall, the soils are not provided with sufficient moisture to sustain vegetation growth. Consequently, these areas lack proper vegetation and develop extremely dry climates, forming a desert.

2. Continental Interiors: Many deserts occur in the interior regions of continents, far away from large bodies of water (oceans or seas). Coastal areas generally experience higher humidity and receive greater rainfall. However, areas located more centrally on the continent often do not benefit from this moisture influence, causing them to have lower levels of precipitation, which enhances the arid and desert-like conditions.
