Quiz on the desert 🏜️

Deserts are arid regions that receive very little rainfall, usually less than 250 millimeters per year. They are characterized by extreme temperatures, which can be very hot during the day and cold at night. Despite harsh conditions, deserts host unique ecosystems with specially adapted plants like cacti and animals such as camels, foxes, and lizards. Deserts can be sandy, rocky, or covered with gravel and salt flats. Major deserts in the world include the Sahara in Africa, the Arabian Desert in the Middle East, and the Gobi Desert in Asia. Human activities in deserts include nomadic herding, mining, and tourism, though water scarcity makes survival challenging.
