Sandstone, a sedimentary rock, is commonly found in desert regions, formed by the accumulation and cementation of wind-blown sand grains.

A butte is a prominent, isolated hill with steep, often vertical sides and a relatively flat top, commonly found in desert landscapes.

Water erosion, particularly through the action of rivers and streams, is the primary process responsible for the formation of deep, narrow canyons with steep sides.

An erg is a large, flat area of desert covered with wind-blown sand, often forming vast sand seas or dunes.

Igneous rocks are formed from the cooling and solidification of molten rock, either above or below the Earth's surface.

A wadi is a dry riverbed or valley that is typically found in desert regions, carrying water only during periods of heavy rainfall.

Fold mountains are characterized by a series of parallel ridges and valleys formed by the folding and erosion of the Earth's crust.

A hamada is a large, flat area of desert covered with small, rounded stones, often formed by the weathering and erosion of rocks.

Metamorphic rocks are formed from the alteration of existing rocks due to heat, pressure, and chemical reactions, without melting.

A playa is a temporary lake that forms in a desert region after heavy rainfall, often occupying a low-lying area with poor drainage.

A canyon is a deep, narrow gorge with steep sides, typically formed by the erosion of a river over a long period of time.

A sabkha is a large, flat area of desert covered with salt deposits, often formed by the evaporation of seawater or groundwater.

Sedimentary rocks are formed from the accumulation and cementation of various materials, including organic material such as plant remains, forming rocks like coal or limestone.

A playa is a large, flat area of desert covered with a thin layer of water, often forming a temporary lake after heavy rainfall.

An inselberg is a large, rounded hill with a smooth, convex profile, often rising abruptly from the surrounding desert.
