2. Temperate deserts: Hot in the summer and cold in the winter; There is more precipitation than tropical deserts; The sparse vegetation primarily consists of widely dispersed, drought-resistant shrubs and cacti or other succulents adapted to the lack of water and temperature variations.
3. Cold deserts: Winters are cold, summers are warm or hot, and precipitation is low; Desert plants and animals have adaptations that help them to stay cool and to get enough water to survive.
