The greenhouse effect refers to the way Earth’s atmospheric gases create a barrier that allows the heat from the Sun to penetrate and be absorbed by Earth’s surface. The heat is trapped, much like in a greenhouse. The greenhouse effect on Venus works so “well” that its surface is 457°C. The greenhouse effect on Earth is not as intense, so it is able to sustain life as we know it.
