Layers of the AtmosphereOnline version Match the layers of the atmosphere to their characteristics. by Rebecca Clark 1 Stratosphere 2 Troposphere 3 Mesosphere 4 Thermosphere 5 Exosphere Location of the ozone layer. Second lowest atmospheric layer. 7 to 31 miles above Earth's surface. Shields organisms from harmful UV radiation. Lowest atmospheric layer. Where weather occurs. The primary location of clouds. Exists from 4 to 12 miles above Earth's surface. 31 to 53 miles above Earth's surface. Where the coldest temperatures in Earth's atmosphere are located. Most incoming meteors vaporize in this layer. The highest layer in which clouds can form. A very sharp incline in temperature happens here. Layer directly above the mesopause. Starts at about 56 miles above Earth's surface. The aurora occur here. Uppermost layer of the atmosphere. Air is extremely thin in this layer. Fades into the vacuum of space.
