Most of which type of electromagnetic radiation is given off by Earth's surface at night? 1
gamma rays
2.
ultraviolet light
3.
visible light
4
infrared rays

infrared rays

Explanation:

The majority of the energy collected by the earth in a day is re-emitted, and the majority of this outgoing radiation is infrared.

infrared rays: -

Heat- longer wavelength than the red part of the spectrum.Absorbed by water, carbon dioxide clouds in the earths atmosphere.

Gamma rays :-

Nuclear explosions and lightning are the primary sources of gamma rays. Before they reach the ground, they are absorbed by the earth's atmosphere.

Ultraviolet light :-

The sun is the only source of UV radiation. Vitamin D is produced in the presence of ultraviolet radiation. It is generally filtered out by the earth's atmosphere; otherwise, it might harm living organisms. It is most readily absorbed by all living things on the planet.

visible rays :-

A portion of the electromagnetic spectrum that is visible to the human eyes.These are not re-emitted back from earth surface.

infrared rays

Explanation:

Infrared A radiation (IR-A) accounts for almost a third of total solar radiation.

Infrared radiation is a part of the spectrum of electromagnetic radiation that continues to the red part of the visible spectrum.

Most of the absorbed energy of the Sun's radiation is converted by the Earth into heat. The surface of the Earth thus heated emits its electromagnetic radiation back into the atmosphere, in the infrared region of the spectrum (long-wave radiation).
