Which wavelength range is primarily responsible for heating the Earth's surface and contributing to the greenhouse effect?
Infrared radiation
The Earth's surface absorbs sunlight and gives off energy as infrared (heat) radiation.
Greenhouse gases such as carbon dioxide and water vapour trap this infrared radiation, which keeps the surface warm.
This trapping of infrared radiation is the greenhouse effect.
Hence, the answer is infrared radiation.
