Averaged over the Earth, over a full year, the amount of radiation absorbed equals the amount of radiation lost to space, less the heat lost from net combustion of fossil fuels (over storage in new plant matter).

What does rad stand for in radiation measurement?
It doesn't "stand" for anything*rad stands for 'radiation absorbed dose'* The rad is an obsolete unit of measure. It is not an abbreviation.According to Anwers.com, it is a "unit of energy absorbed from ionizing radiation, equal to 100 ergs per gram or 0.01 joules per kilogram of irradiated material. It has been replaced as a standard scientific unit by the gray."The gray is the official SI unit equal to one joule per kilogram.
What transfers thermal energy through space?
There are three mechanisms by which thermal energy (heat) is transferred through space: conduction, convection, and radiation.1Radiation is the transfer of heat energy through empty space. All objects with a temperature above absolute zero radiate energy at a rate equal to their emissivity multiplied by the rate at which energy would radiate from them if they were a black body. No medium is necessary for radiation to occur; radiation works even in and through a perfect vacuum. The energy from the Sun travels through the vacuum of space before warming the earth. Also, the only way that energy can leave earth is by being radiated to space.The transfer of thermal energy through space is called Radiation
How fast does the earth orbit the sun in kilometers seconds?
The average speed of the earth in orbit is around 30 km/sec or 108,000 km/h. The planet moves faster when it's closer to the sun and slower when it's further away, sweeping out equal areas in equal time.
When an object covers equal distances in equal amount of time is?
When an object travels covers equal distances in equal amount of time it can be said that it is traveling with constant speed. speed = distance/time. Unit of speed is m/sec. speed is a scalar quantity.
What happens when light strikes a opaque object?
All the light is absorbed, except that portion of the spectrum matching the object's color. That particular bandwidth is reflected. Hence a yellow object appears yellow, and a blue object appears blue. Black objects absorb light without reflecting any, while white objects reflect almost all the visible light which strikes them. The object may then emit the absorbed energy in the infrared spectrum (heat).
Is the balance between incoming radiation and outgoing heat called radiation balance?
Is the equation of incoming and outgoing thermal radiation. Incoming radiation or solar radiation is called short wave and the radiation emitted from the earths surface and atmosphere (heat radiation) is in the infra -red spectrum and is known as long wave radiation.
What is a kilogray?
A unit of absorbed energy from ionising radiation equal to one thousand grays. A gray (Gy) is the SI unit of absorbed radiation dose of ionising radiation, defined as the absorption of one joule of ionising radiation by one kilogram of matter (usually human tissue).
If heat is produced by a chemical system?
An equal amount of heat will be absorbed by the surroundings.
If heat is released by chemical systems an equal amount of heat will be?
absorbed by the surroundings

When matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
After the absorption, the matter has added energy equal to 'hf' the energy of the absorbed photon.
What is the amount of energy given off or absorbed when electrons change energy states equal to?
E=hv
