Explain in full sentences with details, the process of how the greenhouse effect occurs.
The greenhouse effect starts when greenhouse gases enter the earth`s atmosphere. The atmosphere is then polluted by the greenhouse gases. These gases abosb the majority of the sun`s energy. The warm energy is later radiated back to the earth which causes the earth`s tempreature to increase.
