The correct answer is option 3: Trapping of solar energy due to atmospheric gases. The Greenhouse Effect refers to the process by which certain gases in the Earth`s atmosphere trap heat from the sun, preventing it from escaping back into space. These gases, including carbon dioxide, methane, and water vapor, act like the glass walls of a greenhouse, allowing sunlight to enter but trapping the heat inside. This natural process is essential for maintaining a stable climate on Earth and keeping temperatures suitable for life. However, human activities, such as burning fossil fuels and deforestation, have increased the concentration of greenhouse gases in the atmosphere, leading to an enhanced greenhouse effect and global warming. Therefore, the Greenhouse Effect plays a crucial role in regulating the Earth`s temperature, but excessive greenhouse gas emissions can have serious environmental consequences.
