Weather and climate are the two major abiotic (nonliving) factors responsible for determining the major geographic ecosystems called biomes.…
Hot, dry plains contrast with snow-capped mountain ranges and well watered river valleys. Dry climatic environments in which evaporation rates are greater than precipitation. They dominate virtually the whole region, the lack of cloud cover makes nights cool or cold and freezes are possible in the winter. Most places have irregular rains.…
In the Alaskan Tundra, abiotic factors include wind, temperature, and sunlight. Abiotic factors are nonliving things that influence or affect the ecosystem and the organisms in it. Factors such as wind, temperature, and sunlight can have a lasting effect on an ecosystem such as an Arctic Tundra. In the Alaskan Tundra, strong and persistent winds rush through the air.…
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 shrubs, grass in some parts and a lot of mosses. The tundra is too cold to be able to grow a lot of vegetation. The animals that live in the tundra are the arctic foxes, musk ox, the snowy owl, lemmings, and the polar bear!…
On the peaks of the highest mountains in Canada are glaciers which have snow that never melts. With snow covering the ground 24/7 there is now possible way vegetation can grow. It is just too cold and they can’t grow upwards with hundreds of pounds of snow on it. In the Tundra the case is almost the same. In the southern Tundra there is almost a glacier but most snow melts in late July-August but the only gives a one and a half month growing season which no big vegetation can grow. Only small shrubs and grasses. In the northern Tundra there is basically a permanent glacier except for maybe a couple of weeks of a growing season which in this case barely anything can…
The Arctic Tundra is among Earth’s coldest, harshest biomes. Tundra ecosystems are treeless regions found in the Arctic and on tops of mountains. The Arctic tundra is mostly located in the Northern Hemisphere but in the Southern Hemisphere, it can be located on islands off of the coast of Antarctica. The high mountain tops of North America, Europe and Siberia are part of the tundra. Also, about half of Canada and most of the Alaskan coast are in the tundra.…
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 the ground.…
Arctic tundra is a biome characterized by cold weather and low growing plants and shrubs and virtually no trees. They are found mainly in regions just below the Arctic ice caps, located at latitudes 55o to 70o North, across North America, Europe, Alaska, Canada and Siberia. They cover 20% of the earth’s surface. The summer season is short, where there are brief periods when the sun shines for almost 24 hours a day and temperatures never go above 45o or 50o F. In winter, temperatures don’t reach above 20o F and average between -20o to -30o F. Tundra biomes receive low levels of precipitation, around 150 to 250 mm of rain per year. Due to the harsh climate, vegetation such as low shrubs, sedges and reindeer mosses have adapted by growing close to the ground and close together, as this helps plants to resist the effects of cold weather and reduce damage caused by snow and ice. Plants are also small and roots are shallow to skim the thin unfrozen layer on top of the permafrost (a thick layer of soil that remains frozen throughout the year. Permafrost is also the reason why there are virtually no trees in tundra biomes, as not enough moisture can percolate the soil). However, in the summer months the top part of the soil partially thaws, forming bogs and ponds, allowing some vegetation to grow.…
Permafrost has a big affect on the soil in the tundra due to this most of the arctic ground is frozen year round in some places in the arctic the ground get warms of enough and the permafrost melts this creates shallow lakes this can cause en explosion of flora and fauna…
The phrase “sex, drugs, and rock and roll” held true to its well-earned spot in 1970’s and 1980’s society. With a new, looser culture, explicit music, raunchy and rambunctious movies as well as a societal focus on many things immoral, it was an era of challenging social norms. As the use of recreational and psychoactive drugs, as well as alcohol, increased, a new problem arose; how does law enforcement and the government undo the damage being made by this new society? Laws were passed, bureaus and commissions were formed, and the President of the United States began what he called “The War on Drugs”. Over the years, some of these solutions have proven to make some impact. The initiation, tactics, and attempts at dealing a major blow to drug abuse have all affected the way America sees drugs today. A new type of warfare had made its way into the country, and after all these years, it has made its fair share of positive and negative effects.…
The natural vegetation regions and soil regions are interconnected in numerous ways. Soil regions as the Tundra soils, or dry climate soils have the potential to affect the type of vegetation that can be grown. Where you would find cold temperatures as the Tundra, you can expect limited vegetation to grasses, mosses, and shrubs. Because the ground has an active layer of permafrost, growing conditions are not suitable for plants and trees. Areas with moist soil as the wet-climate regions, you are expected to find trees and plants resembling the mixed forests, boreal and taiga forest, as well the deciduous forests. The Grasslands are located in the dry climate soils situated in the Prairie Provinces. Due to the dry temperatures there are very insufficient amount of trees, and consisting of large rolling terrains of grasses. To conclude location is a dependent factor on the type of vegetation a region will come to…
· Describe the major terrestrial biomes: Differenciated by temperature and percipitation and by plant growth from that are adapted to these conditions. Three group, those in cold, temperature (grassland/cold), and tropical seasonal.…
There are five causes of climate, latitude, elevation, ocean/wind currents, terrain and closeness to large bodies of water. There are many types of climates. Two interesting climates are the Mediterranean climate and Ice Cap climates. These two climates are very different. The Ice cap climate is located only near the poles, while the Mediterranean climate is mostly located on the western sides of continents.…
Climate change in the Tundra will cause very alarming problems that hold the potential to affect the present generation and those to come. Climate change is an adjustment of global or regional weather patterns. The Tundra has a frigid climate, frozen soil, and animals such as lemmings and polar bears. Additionally, there are flowers and grasses throughout the land. Nutrients for such plants come from dead and decomposing biological matter. Essentially all the precipitation is in the form of snow due to the average temperature of approximately 7.75°F (Google.com). Despite efforts to reduce carbon emissions, the permafrost is melting at startling rates due to human interference.…
In this essay, I will comment on Morton Winston’s definitions of technology, then apply the six aspects in every technology to an artifact selected from Friedman’s essay “The World is Flat”. The six aspects include first the skills, techniques, human activity forms, or socio-technical practice; second, resources, tools, and materials; third, technological products or artifacts; fourth, end, intention or functions; fifth, background knowledge; and lastly, social context in which the technology is designed, developed, used, and disposed of, and the artifact that I will apply is Nike.…
