Heat radiation is the process of energy being released from a hot object. This energy is released in the form of electromagnetic waves and travels through space. Heat radiation is used in everyday life, from cooking on a stove to the sun warming the Earth.
What is Heat Radiation?
Heat Radiation: The transfer of energy from one object to another through the emission of electromagnetic waves. These can travel through the vacuum of space.
Do you think heat radiation is a major cause of climate change?
- Yes, definitely
- No, not at all
- I'm not sure
More than half of the energy from the Sun is absorbed by the atmosphere before it reaches the Earth's surface. Radiation from the Sun is composed of visible light as well as infrared radiation, which is invisible to the human eye. The Earth's atmosphere is composed of molecules that radiate energy due to their temperature, creating a natural greenhouse effect.
