The transmission of heat through a medium without the motion of the medium.
Heat transfer in a gas or liquid by the circulation of currents from one region to another.

Greenhouse gases are gases that trap heat within the Earth's atmosphere. What would be the most likely result of an increase in the amount of greenhouse gases in the atmosphere?
a change in global wind patterns
a decrease in global rainfall

Over the past 60 years, the level of carbon dioxide in the atmosphere has been continually increasing. Many scientists hypothesize that this increase has led to an imbalance in the carbon cycle and a climatic trend known as global warming.
In which of the following ways could humans help the carbon cycle return to normal?
pump nitrogen and oxygen into the air to help rebalance the atmosphere
cap volcanoes so that they do not release more carbon dioxide
cut down trees and other large plants that depend on carbon dioxide
reduce the amount of fossil fuels they combust
