ASVAB General Science Atmosphere Practice Test 164410

Question 1 of 5
Thermosphere

Temperatures again increase with altitude in the thermosphere which is the hottest (4,530 °F / 2,500 °C) atmospheric layer due to direct exposure to the Sun's radiation. However, the gas in this layer is highly diluted so even though the atoms of gas may be very high in temperature, there are too few of them to effectively transfer much heat.

Which is the proper order of Earth's atmospheric layers from the surface up to space?

stratosphere, troposphere, mesosphere, thermosphere

troposphere, stratosphere, mesosphere, thermosphere

mesosphere, thermosphere, stratosphere, troposphere

thermosphere, mesosphere, stratosphere, troposphere
