important percentage of the globes biodiversity. This ecosystem is estimated to house 50% of all plant, insect and animal life. Covering less than 7% of Earth’s surface, it nonetheless is attributed with producing 20% of our oxygen supply. This unique biome arcs like a green arrow along the equatorial line. Its primary locations are South America, Central Africa and South-East Asia. Each region is facing varying degrees of serious deforestation. The result being widespread loss of humid tropical forest

the earth, humans, and species. There are three types of forests. The three types include “tropical, temperate, boreal forests” (The forest biome p. 1, 2006). Recently forests occupy about “one-third of Earth’s land area, and account for over two-thirds of the leaf area of land plants, and contain about 70% of carbon present in living things” (The forest biome p. 1, 2006). Forests produce vital oxygen and provide homes for people and wildlife. Forests play a critical role in mitigating climate change

combusted. Once that occurs the exchange CO2 in the atmosphere and CO2 dissolved in water are continually exchanged. Finally, combustion converts fossil fuels and plant material into CO2 and then the cycle starts all over with photosynthesis. 2. A biome is a large natural community of plants and wildlife in a major habitat, like a tundra, desert or forest. In addition, it is made up of all the habitats of a community that make up comparable

precipitation in the tropics? 2. Use what you know about atmospheric circulation and seasonal changes in the sun’s orientation to earth to explain the highly seasonal rainfall in the tropical dry forest and tropical savanna biomes. (Hint: Why does the rainy season in these biomes come during the warmer months?) Heating of the earth surface and atmosphere and influences patterns of precipitation the sun heats the air at the equator causing it to expand and rise. This warm moist air cools as it

His Ideals and concepts were beyond that of the time he lived in. He believed that the earth was a system that had a perfect compensation process. This is system could handle any kind of change or natural

The largest member of the genus Mustela in Britain, the European Polecats has a weasel like body, short legs and a broad head. During the winter it’s coat is thick, lustrous and glossy, but in the summer is thinner and appears somewhat faded. During the winter they become less active and emerge during the day more than they would in the summer. They currently occur in England as far north as Cheshire, south to Avon and reaching east to Leicester as well as in most of rural wales. They inhabits lowland

Water may be treated differently in different communities depending on the quality of the water that enters the treatment plant. Typically, surface water requires more treatment and filtration than ground water because lakes, rivers, and streams contain more sediment and pollutants and are more likely to be contaminated than ground water. Drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents. Public drinking water systems use various

largest continent that extends from the Gulf of Darien in the northwest archipelago of Tierra del Fuego in the south. South America’s extreme geographic variation contributes to the continent’s large number of biomes. South America’s coastal plains’ dry desert biome rises to the rugged alpine biome of the Andes mountains. One of the continent’s river basins (the Amazon) is defined by dense, tropical rain forest, while the other (Paraná) is made up of vast grasslands. Mountains and coastal plains generally

Environmental science – U1L8 Most rain forests are located near the equator. Rain forests have a tropical wet climate and are quite humid all the time. The yearly rainfall is often more than 100 inches a year. Tropical rainforests produce almost half of the oxygen on earth. Scientists say that more than half of all the world's plant and animal species live in tropical rain forests. Rainforests only cover less than 6% of Earth's land surface. The rain forest is home to the greatest biodiversity
