The trapping of heat in the Earth's atmosphere is known as the "greenhouse effect." This phenomenon occurs when certain gases in the atmosphere, such as carbon dioxide, methane, and water vapor, absorb and emit infrared radiation. While the greenhouse effect is crucial for maintaining Earth's temperature and supporting life, human activities, such as burning fossil fuels, have intensified this effect, leading to global warming. Understanding this process is essential for addressing climate change and managing environmental impacts on a global scale.
