Hot and Cold Deserts

• desert-a dry habitat that gets very little rain.  
• hot deserts are hot in the day and cold at night.
• soil is sandy and rocky.
• desert plants store water in stems and leaves
• some leaves curl up in the day to hide from sunlight
• lizards, snakes, and turtles live in deserts
• they do not need a lot of water to survive
• they eat other plants or animals to get water
• they have pale colors to stay cool and hide from other animals
• most sleep in the day and come out at night when it is cooler
• the arctic is a cold desert near the north pole
• it is cold and dry
• thick fur and blubber (fat) helps animals stay warm
• reindeer, walruses, foxes, and polar bears live there
• many small low plants
• no trees
• tiny leaves because roots grow shallow (ground is frozen all year long)
