What is the primary cause of the greenhouse effect?
Correct Answer: Greenhouse gases trap heat in the atmosphere.
- Step 1: Understand that the Earth receives energy from the Sun in the form of sunlight.
- Step 2: Know that some of this sunlight is absorbed by the Earth's surface, warming it.
- Step 3: Realize that the Earth then releases some of this heat back into the atmosphere as infrared radiation.
- Step 4: Learn that greenhouse gases, like carbon dioxide and methane, are present in the atmosphere.
- Step 5: Understand that these greenhouse gases trap some of the heat that is trying to escape back into space.
- Step 6: Conclude that this trapping of heat by greenhouse gases is what causes the greenhouse effect.
