Deserts are typically defined as arid regions with little rainfall and sparse vegetation. They can be found on every continent and cover about one-third of the Earth's land surface. Deserts are characterized by their extreme temperatures, with hot days and cold nights, and their unique landscapes, which can include sand dunes, rocky outcrops, and canyons.

Despite their harsh conditions, many species of plants and animals have adapted to survive in desert environments.
