The Atmosphere When we look up at the sky we are looking through layers of gases called the atmosphere These iayers wrap around Earth like a pile of blankets some thick and others thin Each layer is made of a mixture of gases covers a range of temperatures and air pressure and has a different effect on the way we ive on Earth 1ere From around 375 miles 600 kilometers Pressure is extremely low gases are very thin and some escape into space Most satellites orbit Earth here Thermosphere Around 53 375 miles 85 600 km Gases are still thin pressure is very low and the temperatures increase with height Bright colored lights pulsate Mesosphere Around 30 53 miles 50 85 km Temperatures are very cold Meteors shoot through and burn up The highest clouds put on a light show over the poles Stratosphere Ranging from 4 30 miles 6 50 km The tips of Earth's highest clouds reach here A layer of ozone gases protects Earth from the Sun's harmful rays Troposphere Ranging from 0 12 miles 0 20 km In this layer we can breathe Oxygen and plants use carbon dioxide to grow The boundary with the stratosphere varies ADD
