Cooling towers of a nuclear power plant

Cooling towers. Steam rising from the coolingtowers of a nuclear power station. The tower coolswater by allowing steam to evaporate into theatmosphere and carry away heat. A tower requires aflow of air and this may be induced by natural ormechanical means. Large cooling towers at powerstations eliminate the problems of thermalpollution in masses of water. The water in thecooling towers is used to cool other coolingcircuits within the power station. As it is notused to cool the reactor core directly, the wateris not radioactively contaminated.

GEOLOGY: K-T boundary - K-T boundary Sussex locality, Wyoming, USA.
The ruler and brush rest on the top of the K-T boundary layer. Below it is a mudstone deposit of the Lance Formation (Cretaceous). Above it is a coal bed of the Tullock Member of the Fort Union Formation (Tertiary). The K-T boundary layer is the gray to white kaolinitic claystone, less than 2 cm thick. On top of it is a darker, laminated layer a few millimeters thick, containing sand grains, many of them showing multiple sets of parallel fractures ("shocked quartz") under the microscope. Iridium can be detected in the claystone layer and in the carbonaceous layer immediately above it.

Greenhouse effect, artwork

Greenhouse effect, artwork. The greenhouse effect is a process by which the Earth warms up. It occurs naturally, but there are concerns that human activities may be increasing its effect, leading to global warming. The surface of the Earth absorbs some solar radiation (yellow arrow), reflects some, and re-radiates some at a longer (infrared, IR) wavelength. Naturally some of this IR passes through the atmosphere back into space, but the build-up of some chemicals in the atmosphere can change its absorbance of radiation. Carbon dioxide, which is emitted by the burning of fossil fuels, is a major greenhouse gas. Global warming could have dire consequences for the planet
