Which is the best description of the greenhouse effect?

Solar radiation passes through the atmosphere, some of which then warms the earth's surface. The remainder is reflected back into the atmosphere. This reflected solar radiation is absorbed by greenhouse gases, causing an increased warming of earth's atmosphere and surface.

Solar radiation is absorbed in the earth's atmosphere by greenhouse gases. The increased concentration of these gases in the atmosphere causes greater heating of the earth's atmosphere and surface.

Solar radiation passes through the atmosphere and warms the earth's surface. Some of this heat is converted into lower energy infrared radiation. The infrared radiation cannot completely pass back through the greenhouse gases in the atmosphere, causing a direct, continued warming of earth's atmosphere and surface.

Solar radiation directly warms the earth's atmosphere, causing convective currents and increased heating of the earth's surface.
