Changes in the Earth's orbital configuration may lead to warming temperatures. These warming temperatures, in turn, may lead to the release of both CO2 and CH4. Increases in these gases may further warm the planet. This is an example of a

A) positive feedback loop.
B) negative feedback loop.
C) neither a positive or negative feedback loop.

Question 2

Despite its high temperatures, why would the thermosphere feel cold to humans?

A) The number of molecules is not high enough to transfer heat to human's skin.
B) Humans would die due to pressure changes before they could experience the intense heat.
C) The atmosphere is denser in the thermosphere and this pressure reduces heat transfer.
D) The average kinetic energy is actually less in the thermosphere than the troposphere.
