The greenhouse effect plays a major role in the climate of a planet. Visit the Greenhouse Effect AstroTour (Links to an external site.), and use what you learn there to choose all the statements below that are correct. Note that 273 K = 0°C = 32°F.

If there were no greenhouse effect, liquid water would not exist on the surface of the Earth.

The Earth has reached thermal equilibrium, emitting the same amount of energy into space as it absorbs from the Sun.

The more carbon dioxide there is in an atmosphere, the stronger the greenhouse effect will be.

Explanation:

Without greenhouse gases like carbon dioxide, the entire Earth would be well below the freezing temperature of water. These gases slow the radiation of infrared light into space, warming the planet until it reaches thermal equilibrium.
