Layer of the Atmosphere that protects from meteorids:

• Stratosphere

• Mesosphere

• Thermosphere

• All of the above

Layer of the earth where temperature decreases as the altitude increases:

• Thermosphere

• Troposphere

• Mesosphere

• A and C are correct

In order from lowest level (starting on the left) to highest level, what is the correct order of the layers of the atmosphere?

• thermosphere, troposphere, mesosphere, stratosphere

• troposphere, mesosphere, stratosphere, thermosphere

• mesosphere, stratosphere, troposphere, thermosphere

• troposphere, stratosphere, mesosphere, thermosphere

What causes GLOBAL winds? ***hint: pay very close attention to the wording of the answers

• movement of air from areas of low pressure to areas of high pressure

• conduction currents caused by cool and warm air

• radiation currents caused by absorbing the Sun's heat

• unequal heating of Earth's surfaces over large areas
