3. A change in density causes a change in temperature in Earth's atmosphere. What
evidence from the text supports this conclusion?
A. "The high temperature indicates the amount of the energy absorbed by the molecules
but with so few in this layer, the total number of molecules is not enough to heat our
skin."
B. "The gases in the mesosphere are now thick enough to slow down meteors hurtling
into the atmosphere, where they burn up, leaving fiery trails in the night sky."
C. "This increase in temperature with height means warmer air is located above cooler
air. This prevents 'convection' as there is no upward vertical movement of the gases."
D. "As the density of the gases in this layer decrease with height, the air becomes
thinner. Therefore, the temperature in the troposphere also decreases with height in
response."
Answer
C. "This increase in temperature with height means warmer air is located above cooler air. This prevents 'convection' as there is no upward vertical movement of the gases."
