For example, what is the reason why greenhouse gases reflect heat from the Earth back to Earth, but not heat from the Sun back to the space?
From what I understand, it has something to do with radiation and emitted waves, but what exactly makes the difference?
In: Planetary Science
It is all down to the wavelengths. Light (visible light) comes from the Sun and passes through the atmosphere, it then hits the ground and warms the ground up. The warm ground then radiates infrared radiation (different part of the spectrum of light) and that doesn’t pass so easily through the atmosphere and basically bounces back down to the Earth off the Carbon Dioxide gas. and so the heat stays “trapped” and warms the planet up. https://youtu.be/_vFRSAs9DiY
