The major cause of the greenhouse effect is carbon dioxide in the atmosphere. To understand this, it is important to comprehend the greenhouse effect itself. The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat from the sun, which causes the Earth's surface to warm up. These gases are known as greenhouse gases.
Among the different greenhouse gases, carbon dioxide plays a significant role. It is released into the atmosphere by various human activities, such as the burning of fossil fuels like coal, oil, and natural gas. This release of carbon dioxide is primarily from sources like power plants, transportation, and industrial processes.
When carbon dioxide is released into the atmosphere, it forms a layer that acts like a blanket around the Earth. This layer allows sunlight to enter the atmosphere but prevents some of the heat from escaping back into space. As a result, the Earth's temperature rises, leading to global warming and climate change.
While soot from coal plants can contribute to the pollution and air quality issues, it is not a direct cause of the greenhouse effect. The main driver is carbon dioxide, which makes it the correct answer to the question.
