What is the primary definition of the greenhouse effect?

The primary definition of the greenhouse effect centers around the warming of Earth's surface as a result of certain gases in the atmosphere, known as greenhouse gases, trapping heat from the sun. When sunlight reaches the Earth, some of that energy is reflected back into space while the rest is absorbed, warming the planet. Greenhouse gases, including carbon dioxide, methane, and water vapor, then trap some of this heat, preventing it from escaping back into space. This process is crucial because it helps maintain a temperature that supports life on Earth.

Understanding the greenhouse effect is essential to comprehending broader climate change discussions, as an increase in greenhouse gases typically leads to a rise in global temperatures, illustrating the delicate balance of Earth’s climate system.
