Quizplus · Accepted Answer

The greenhouse effect is a natural process that occurs when certain gases in the Earth's atmosphere trap heat from the sun, keeping the planet warm enough to sustain life. However, human activities, such as burning fossil fuels and deforestation, have increased the levels of greenhouse gases in the atmosphere, intensifying the natural greenhouse effect and causing global warming.
