Detailed explanation-1: -Greenhouse gases include carbon dioxide, methane, nitrous oxides, and water vapor. (Water vapor, which responds physically or chemically to changes in temperature, is called a “feedback.") Scientists have determined that carbon dioxide’s warming effect helps stabilize Earth’s atmosphere.
Detailed explanation-2: -The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases.
Detailed explanation-3: -Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth. This heats up the atmosphere and raises the planet’s average temperature.
