The Seasons

Beautiful Earth, home to plants, animals and humans, is the third planet from the Sun. It’s the fifth largest planet. Some of the other planets have atmospheres, seasons and even water, but only Earth combines all these elements in just the right way. Earth is the only place in the solar system where life is known to be found.

Most of the places on Earth experience four seasons, caused by the earth’s rotation and tilt. When it’s winter in the northern hemisphere, it’s summer in the southern hemisphere, and vice versa. The Earth is surrounded by a blanket of gases that protects it from the sun. The atmosphere is mostly nitrogen – about 78 percent. The atmosphere also contains oxygen.
