Green house effect is the heating up of the Earth’s atmosphere which is due to A. The ultraviolet rays B. G-rays C. The infra-red rays D. X-rays

X-rays are a type of electromagnetic radiation with a wavelength shorter than G-rays. They are used in medical imaging and can be used to treat cancer.

Infrared rays are a type of electromagnetic radiation with a wavelength longer than visible light. They are emitted by hot objects, and can be felt as heat.

The greenhouse effect is important because it helps to keep the Earth’s surface warm enough for life to exist. However, human activities such as burning fossil fuels are increasing the amount of greenhouse gases in the atmosphere, which is causing the greenhouse effect to become stronger. This is leading to global warming, which is causing the Earth’s temperature to rise.
