Cold deserts Short, warm summersLong, cold wintersFound in places near the north and south poles
Desert PlantsMany plants are found in the desert. They usually grow close to the ground.These plants have special parts that help them save water.The special parts are: thick stem, shallow and wide roots, and thick skin covered with spines instead of leaves.
Desert AnimalsThere are many animals in the desert.They can survive by eating other animals or by eating plants that store water.To protect them from the hot sun, they stay in the shade or in their shelter.Animals may build their shelters inside plants.Some animals sleep during the day and are active at night. Some animals have hard shells to protect them from losing much water.More animals live in hot deserts than in cold deserts.
