1. Solar Radiation Arrives: The sun emits energy in the form of electromagnetic radiation, including visible light, infrared radiation, and ultraviolet radiation. This radiation travels through space and reaches Earth.

2. Absorption and Reflection: About 30% of the incoming solar radiation is reflected back into space by clouds, ice, and the Earth's surface. The remaining 70% is absorbed by the Earth's surface, atmosphere, and clouds.

3. Earth's Surface Warms: The absorbed solar radiation increases the temperature of the Earth's surface, oceans, and atmosphere.

4. Infrared Radiation Emission: As the Earth warms, it emits infrared radiation back into space.

5. Greenhouse Gases Trap Heat: Certain gases in the atmosphere, called greenhouse gases (like carbon dioxide, methane, and water vapor), are very good at absorbing infrared radiation. They act like a blanket, trapping the heat near the surface.

6. Warming Effect: The trapped infrared radiation prevents the Earth from cooling down as quickly, leading to a warmer planet.

Without the greenhouse effect, the Earth would be much colder and uninhabitable. However, human activities are increasing the concentration of greenhouse gases in the atmosphere, leading to a phenomenon called global warming, where the Earth's average temperature is rising.

Here's a simple analogy: Imagine a car with the windows rolled up on a sunny day. The sun's energy enters the car, heating the interior. The windows act like greenhouse gases, trapping the heat inside. The car gets progressively warmer.
