Exosphere - the outermost layer of the Earth's atmosphere, where atmospheric pressure and temperature are low. Ionosphere - the atmospheric layer between the mesosphere and the exosphere; it is part of the thermosphere. Mesosphere - the atmospheric layer between the stratosphere and the ionosphere. Stratosphere - the atmospheric layer between the troposphere and the mesosphere. The stratosphere is characterized by a slight temperature increase with altitude and by the absence of clouds. Thermosphere - the layer of the atmosphere located above part of the ionosphere (starting at the coldest part of the atmosphere) and below outer space; it consists of the exosphere and part of the ionosphere. Troposphere - the lowest layer of the Earth's atmosphere. The weather and clouds occur in the troposphere. |
