Radiant energy (heat and light).
Heat from the Sun received on earth.
The energy from the sun that is received by the earth is known as solar radiation, or solar energy. This energy is essential for sustaining life on earth and driving various natural processes, such as photosynthesis and weather patterns.
When the amount of energy received from the sun and the amount of energy returned to space are about equal, it is called energy balance or radiative equilibrium. This balance helps maintain the Earth's overall temperature and climate.
radiation balance
Energy from the sun or across distances can be received without objects touching through electromagnetic radiation, such as light or heat, which can travel through empty space.
radiation balance
It's the amount of energy given out by the sun, and the energy received by the earth. Within that is the energy reflected and the energy given off from the earth.
The Sun radiates its energy in every direction. The amount of energy received per square meter of exposed surface will decrease by the square of the distance. So, if you double the distance, the amount of energy received will be reduced to one-fourth; if you triple the distance, the energy will be reduced to one ninth.
radiation received from the Sun!! :D
When the amount of energy received from the sun and the amount of energy returned to space are about equal, it is called "radiative equilibrium." This balance is crucial for maintaining a stable climate, as it indicates that the Earth's energy budget is in balance, preventing significant warming or cooling over time.
One common instrument used to measure the energy from the sun is a pyranometer. Pyranometers are designed to measure the solar radiation flux density, which represents the amount of energy received from the sun per unit of time and area.
The vast majority of the energy Earth receives from the Sun comes in the form of electromagnetic radiation, be it visible light, UV or smaller wavelengths (mostly blocked by the upper atmosphere), IR, microwave (responsible for things heating up under the sun by making the molecules vibrate); also some energy is received as kinetic energy via solar winds/ flares.
