How much of the earth is covered by warm desert?

Answer 1

Deserts cover about 20% of the Earth's land surface. This includes both hot and cold deserts. Some well-known desert regions include the Sahara in Africa, the Arabian Desert in the Middle East, and the Mojave Desert in the southwestern United States. Despite their harsh conditions, deserts are home to a wide variety of plants and animals that have adapted to the dry climate.

Answer 2

Almost a third of Earth's land surface is occupied by desert, most of it icy or rocky rather than covered with sand dunes. And a substantial percentage of it supports animal and plant life.

Desert areas are defined as those regions with less than 250 mm (10") of rainfall per year, or with a net loss of water due to evaporation. This includes about 10% of the Earth's total surface, or about 33% of the Earth's land surface.

Answer 3

Approximately one-third of the Earth's land surface is covered in deserts. Deserts are defined as areas that receive very little rainfall, typically less than 250 millimeters (10 inches) per year. The largest desert in the world is the Sahara Desert in northern Africa, which covers an area of about 9 million square kilometers (3.5 million square miles).

Other major deserts include the Arabian Desert, the Gobi Desert, the Australian Desert, and the Atacama Desert. Despite their arid conditions, deserts are often home to a diverse range of plant and animal species that have adapted to survive in the harsh environment. Deserts also play important roles in the Earth's ecosystem, such as regulating global temperatures and serving as habitats for unique species.
