They host specialized flora and fauna adapted to extreme conditions. Various desert types are defined by precipitation and temperature, with unique geological features like dunes and stone pavements. The text explores human interaction, cultural significance, and threats like desertification.

Vegetation imposes a frictional force on the wind to reduce its effectiveness. Thus, an environment devoid of vegetation is best. These conditions are met in deserts found on every continent of the world. In most cases, wind erosion predominates over deposition leaving a surface of stones. Only one quarter of Earth's deserts are partially or completely covered by sand.

Countermeasures like sustainable practices and soil restoration are needed but face challenges. It highlights projects like the Regeneration Project in Ethiopia, which applies innovative grazing methods to restore grasslands and sequester CO2.
