The earth is surrounded by layers of gases, our atmosphere. They are kept near the earth’s surface by gravity. Our atmosphere filters the sunlight and keeps dangerous rays from reaching our planet. Without such a filter it would get too hot during the daytime. At night it prevents heat from escaping so it does not get too cold.
Without an atmosphere life on our planet would not be possible. It also makes our world a more pleasant place to live. Air carries sound waves, which let us hear voices or listen to music. The atmosphere creates rainbows, makes the sky turn blue on clear days and the sun red when it sets
