How can warping of Earth’s crust create a playa basin?

Warping of the Earth’s crust, a process known as epeirogeny, can create a playa basin by causing broad, gentle movements of the crust that result in the formation of enclosed depressions.1

When these tectonic movements occur, they can interfere with natural land-drainage patterns, effectively trapping water and sediment in low-lying areas. Over time, these depressions become sites for the accumulation of salt and clay, forming the characteristic flat, enclosed basins known as playas. Notable examples of playa basins formed through such crustal warping include Lake Eyre in Australia, Lake Chad in central Africa, and Shaṭṭ al-Jarīd (Chott Djerid) in Tunisia.21
