The atmosphere provides the Earth with all the gases necessary for life
The answer is: A layer of a mixture of gases that surrounds the Earth and is drawn to it by gravity.
The atmosphere supplies the earth with all the essential gases needed for life. Oxygen, nitrogen and carbon dioxide are among the most important gases in the atmosphere that help sustain life on Earth. All living things need oxygen for respiration and plants need carbon dioxide in order to carry out photosynthesis. Nitrogen is also essential for the growth of many organisms. Without these essential gases, life on Earth would be impossible. The atmosphere also acts as a shield against the sun's harmful rays and keeps temperatures on the planet relatively stable. It is an incredible system that enables us to live and thrive on this planet.
