radiations can cause damage to human health‚ ecosystems and to the global climate. They can cause skin cancers and catatracts of the eye‚ as well as decrease the immune reactions‚ making humans vulnerable to infections‚ diseases. They can also kill plankton‚ thereby destroying the marine ecosystems. Many plants are also unable to tolerate an increase of whole ecosystems‚ threat to the food security of the world‚ are some of the other effects.

Units (JTUs). Background Turbidity is a measurement of how cloudy water appears.

some types of graptolites floated on the surface of the oceans while others lived in deeper water over the self-edge and upper slope and some lived at great depths. Graptolites lived at all levels of the water column and their main food source was plankton. However‚ we don’t know for sure how graptolites lived because there is not enough information about them to link them to any living organisms. 3. 3-3A. a) Genus: Monograptus b) Order: Graptoloidea 3-3B. a) Genus: Tetragraptus

El Niño is a climate pattern that describes the unusual warming of surface waters along the tropical west coast of South America. El Nino has an impact on ocean temperatures‚ the speed and strength of ocean currents‚ the health of coastal fisheries‚ and local weather from Australia to South America. El Niño events occur irregularly at two- to seven-year intervals. However‚ it is not a regular cycle‚ or strictly predictable in the sense that ocean tides are. El Niño has long been recognized
