STRUCTURE OF THE ATMOSPHERE

Match the following. Match the items in the left column to the items in the right column. 1.exosphere a region in the upper stratosphere where ozone is concentrated. 2.ion layer of the atmosphere just above the troposphere where the temperature remains fairly constant 3.ionosphere the layer of the atmosphere just above the stratosphere; burns up most meteors 4.mesosphere an electrically charged atom 5.ozonosphere the sub-layer of the thermosphere where the atmosphere blends into space 6.stratosphere a sub-layer of the thermosphere containing ions 7.thermosphere layer of the atmosphere above the mesosphere where temperatures are the highest in the atmosphere

EXOSPHERE - the sub-layer of the thermosphere where the atmosphere blends into space ION - the sub-layer of the thermosphere where the atmosphere blends into space IONOSPHERE - a sub-layer of the thermosphere containing ions MESOSPHERE - the layer of the atmosphere just above the stratosphere; burns up most meteors OZONOSPHERE - a region in the upper stratosphere where ozone is concentrated STRATOSPHERE - the layer of the atmosphere just above the troposphere where the temperature remains fairly constant THERMOSPHERE - llayer of the atmosphere above the mesosphere where temperatures are the highest in the atmosphere TROPOSPHERE - layer of the atmosphere nearest the earth where most weather changes occur
