Which statements accurately describe the greenhouse effect? Check all that apply.It is caused by liquids on Earth’s surface.It is caused by gases in Earth’s atmosphere.It warms up Earth’s surface and the lower atmosphere.It cools down Earth’s surface and the lower atmosphere.It maintains Earth’s normal atmospheric pressure.It maintains Earth’s normal range of temperatures.

Greenhouse gases in Earth’s atmosphere absorb and re-emit heat, reducing how quickly energy escapes to space. This warms Earth’s surface and lower atmosphere and helps keep temperatures within a range that supports life. The effect is caused by atmospheric gases, not surface liquids, and it does not maintain atmospheric pressure.
