TUNDRA The Tundra is the coldest of all the Biomes and being situated in the extreme north of the planet has desert like conditions. It has extremely low temperatures‚ poor nutrients‚ and short growing seasons. There is a very low precipitation of less than five inches a year which is coupled with strong‚ dry winds. There is a very large annual amount of snowfall in the region which surprisingly is advantageous to plant and animal life as the snow provides and insulation layer on the surface of

there are cold ocean currents. Each region in which the Mediterranean shrublands and woodlands occur is island-like in character and thus there is frequently a high degree of endemism. Comparative studies of the several regional expressions of this biome reveal interesting examples of convergent evolution in plant families and birds (but not among reptiles or small mammals) on the different continents. Climate: The Mediterranean Climate (Cs) is unique in that the wet season coincides with the low

Most negative impacts came from land-based sources. Oils spills‚ garbage‚ acidification‚ untreated sewage‚ overfishing and marine litter are prime examples of negative impacts humans did to the marine biome. People have done positive impacts also to keep animals living in the marine biome living. Humans have picked up trash from beaches‚ prevented oil spills‚ watched what they put down sinks‚ prevented dumping waste into the ocean and many other positive things. Predation is the relationship

The Tundra is an enormous biome. It covers about one fifth of the earth! That is a good part of the Earth. Greenland is a very good example of the tundra. It is located near the top of the world‚ near the north pole! The most distinctive characteristic of the tundra‚ is its permanent layer of permafrost‚ which means it has a thick layer of frozen soil throughout the year. The latitude of the tundra is 66.5625 degrees north‚ 0 degrees east. The tundra does not have many types of vegetation. It has

The Arctic and areas that are in higher latitudes have a higher rate of warming and this pattern is expected to continue as climates everywhere changes and temperatures go up. As Earth warms up‚ the glaciers in the Arctic start to melt‚ and species such as the polar bear and the arctic fox that depend on the sea ice‚ will start to disappear

Reading Material: Realms of the Earth Astro-physicists and scientists believe that there could be quite a few planets in the Universe similar to our planet Earth. There is also a probable chance that some form of life prevails and sustains in one of such planet. However‚ so far as we presently know‚ the Earth is the only planet which supports life which makes it a very unique planet. It is therefore imperative (very important and necessary) for us to understand the spheres of the Earth as the spheres

The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth‚ a closed (apart from solar and cosmic radiation)‚ and self-regulating system.[1] From the broadest biophysiologicalpoint of view‚ the biosphere is the global ecological system integrating all living beings and their relationships‚ including their interaction with the elements of the lithosphere‚ hydrosphere‚ and atmosphere. The biosphere is postulated to have evolved‚ beginning through a process of biogenesis or biopoesis
