Only about 10% of Brazil ’s rain forests have been cut to date‚ but cutting goes on at an uncontrollable rate. Since pre-agricultural times the world ’s forests have declined one fifth from 4 to 3 billion hectares. Temperate forests have lost 35% of their area‚ subtropical woody savannas

Topic: Asia‚ A Geographical Study By:Manahil Fayaz Asia Asia is the Earth ’s largest and most populous continent‚ located primarily in the eastern and northern hemispheres. It covers 8.8% of the Earth ’s total surface area and comprises 30% of its land area‚ and has the largest coastline‚ at 62‚800 kilometres (39‚022 mi). Asia is generally defined as comprising the eastern four-fifths of Eurasia. Asia is subdivided into 48 countries‚ two of them (Russia and Turkey) having part of their

factors are the primary determinants of species composition in a community‚ and organisms are largely interdependent on each other. According to organismic concept it is expected that an entire community or biome will respond as a unit and to relocate as climatic conditions change. Pleistocene biome migration in response to multiple glaciations‚ the accordian effect‚ is a classic example of this model (Wright‚ 1984). In contrast‚ Wright (1984) further explained that the individualist expects each species

The country I have chosen to visit is Costa Rica. It is a tropical rain forest biome with an average winter temperature of 79 degrees Fahrenheit in the winter and 81.5 degrees Fahrenheit in the summer. The average rainfall is 9.18 inches per month in the dry season and 13.81 inches in the “rainy” season. Some plants found in this biome are the Parrot Flower‚ the Carambola (star fruit)‚ the Cas Guava and Saragundi. The national flower in Costa Rica is the orchid. Some of the animals

EARTH SURFACE REALMS 2And3 We can look at Earth’s surficial "layers" as being comprised of several major realms or "geospheres": the atmosphere‚ lithosphere‚ hydrosphere‚ biosphere and pedosphere. The reference to "sphere" applies because Earth is spherical‚ and hence layers around it form somewhat spherical shells at the outermost edges of the solid planet. The atmosphere‚ biosphere and lithosphere more completely encircle Earth‚ while the hydrosphere and pedosphere tend to be more discontinuous

Wild Animal Profiles African Elephant | Mammal. The largest living land mammal‚ the African elephant weighs 3500 to 7000 kilograms (3.5 to 7 tons) and stands 3.4 meters (11 feet) high. The elephant’s remarkable trunk serves variously as a nose‚ arm‚ hand‚ foot and multi-purpose tool. The trunk is strong enough to uproot a tree and delicate enough to pick berries‚ and it enables the elephant to reach as high as 7 meters (23 feet). Humans can hear only 20% of the vocal sounds an elephant makes;
