Here's how it works:
* Radiation: The Sun emits solar radiation in the form of electromagnetic waves, which travel through space and reach Earth.
* Reflection: Some of this radiation is reflected back into space by clouds, ice, and other reflective surfaces on Earth. This is why we see the sky as blue – scattered blue light is reflected back to our eyes.
* Absorption: The remaining radiation is absorbed by the Earth's surface and atmosphere. This absorbed energy warms the planet.
* Radiation (again): The Earth then emits its own radiation, primarily in the form of infrared radiation. However, some of this infrared radiation is trapped by greenhouse gases in the atmosphere, further warming the planet.
So, sunlight is radiated by the sun, and then some of it is reflected back into space. The remaining radiation is absorbed and warms the Earth, and the Earth then radiates its own energy. This continuous process of radiation and reflection helps regulate the Earth's temperature.
In short, the Earth's atmosphere acts like a complex mirror, reflecting some of the sun's radiation while absorbing and re-radiating the rest.
