What is the greenhouse effect? The cooling of Earth due
to air pollution
The heating of a solid,
such as a rock
The warming of a planet
due to trapped radiation.

the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

The warming of a planet due to trapped radiation.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
