               What is the atmosphere?

               The atmosphere is the air that surrounds the Earth.





               What is the importance of the atmosphere?

               The atmosphere is important to life on Earth. It only allows in


               sunlight that helps to keep the Earth warm and it blocks out harmful


               radiation.

               The atmosphere keeps the temperature on Earth suitable for life.

               and freezing nights.

                atmosphere consist of?

                It consists of five layers, the

                closest to the Earth is the


                thickest. Each layer has an


                important role in making


                Earth liveable.
