Hydrogen has been around since atoms first formed in the residue of the Big Bang, and is the most abundant element by far. Despite billions of years of countless stars fusing hydrogen into helium it still makes up 75 per cent of the detectable content of the universe.
Earth's Energy Balance extended definition. Earth's Energy balance describes how the incoming energy from the sun is used and returned to space. If incoming and outgoing energy are in balance, the earth's temperature remains constant. Earth's Energy Balance why do i care both.
Radiation Balance for Both Earthâs Surface and Atmosphere. The incoming solar radiation is absorbed at Earthâs surface (51 units) and by the atmosphere and clouds (19 units). This is balanced by the infrared radiation emitted from Earthâs surface (6 units) and from the atmosphere (64 units) which are both lost to space. Radiation Balance for both Earth's Surface and Atmosphere.
