Question

Based on information discussed previously in the course, you know that average temperatures in the troposphere __________ with increasing elevation because the atmosphere is heated __________.

A) Increase, from below
B) Decrease, from below
C) Increase, from above
D) Decrease, from above

Answer 1

Average temperatures in the troposphere decrease with increasing elevation because the atmosphere is heated from below. Therefore, the correct answer is B) Decrease, from below.

Step-by-step explanation:

Based on the information provided, you can conclude that average temperatures in the troposphere decrease with increasing elevation. This is because the atmosphere is primarily heated from below. Hence, the correct answer to the question is B) Decrease, from below.

The troposphere, which is the lowest layer of Earth's atmosphere, warms up due to the heat coming from the Earth's surface, which is absorbed and then reradiated by the surface and gases in the atmosphere. As altitude increases, the atmosphere becomes thinner, and the air is less able to absorb and retain heat, leading to a decrease in temperature with elevation.
