Kinds of Habitats
A habitat is a place where animals and plants live. Each habitat has different characteristics from others, and different types of animals living there. Some examples of habitats are an ocean, a forest, and the Arctic. The habitat an animal lives in provides everything the animal needs to live. These needs include air, food, shelter, space, water, and light. Oceans cover almost three fourths of the Earth’s surface. They contain 97% of Earth’s water. There are five major oceans that cover Earth: the Atlantic, Pacific, Indian, Arctic, and Southern Oceans. Deserts are large. They cover about 20% of Earth’s land area. Rainforests are hot and humid. The temperatures are high, and there is a lot of rain. The Arctic is a very cold, windy, and often snowy habitat.
