The wind can become arid and dry and cause desert like conditions in non-desert areas, thus expanding the size of a desert. As temperatures continue to rise with global warming, it is causing glaciers and ice caps to melt in the northern areas. The Earth consists of seven major belts. Three of the belts experience high amounts of rainfall and four of the belts experience low amounts of rainfall. Dry hot deserts lie in a subtropical region.
Erosion is powerful among desert and glacial areas. Erosion is powerful because of high winds and the way rocks along with sand dunes in the desert are formed. Water erosion also plays a huge part in redeveloping the landscape of deserts by transferring sand from one region to another. Glaciers are created by the thickening of ice and snow. As a result of glaciers tends to float toward the outside using the pressure of its own weight.
Winter Climates Winter on Antarctica is between March and August. In the interior regions there are extremely low temperatures. Several months are in complete darkness. Fierce snowstorms make life almost impossible in winter. Winter temperatures are also influenced by latitude, elevation and by the shortage of sunlight during the cold times.
What is acid rain? Acid rain or acid deposition is a broad term that describes any acidic form of precipitation from the atmosphere. There are two types of acid deposition: wet and dry. Dry deposition includes acidic particles, gases and dust that are deposited from the atmosphere, whereas wet deposition includes rain, hail, snow and fog. Unlike dry deposition, winds can blow wet deposition hundreds of miles away from the source of emission, making it an issue for everyone.
What is acid rain? Acid rain is any form of precipitation with high levels of nitric or sulfuric acids. It can also come in the form of snow, fog, and tiny bits of dry material that settle to Earth. What effects does it have on plant material? It robs the soil of essential nutrients and releases aluminum in the soil, which makes it hard for trees to take up water.
Description of a haboob Haboob comes from an Arabic word “habbe”, which means wind. “Haboob is a type of an intense dust storm usually carried on an atmospheric gravity current” (Weather Online, 2011). This type of dust storm is common in arid areas. They have occurred in Sahara desert and Arabian Peninsula. In America, haboobs are common in the deserts of Yuma, Arizona and Phoenix.
It turns into a river because of all the water the mountains have and then creates a path. Rivers cause erosion. Runoff from rivers cause rocks to erode. Because of gravity, runoff, and the sediment it has, to move downhill. An example of this sheet erosion.
Wegener's theory also provided an alternate explanation for the formation of mountains (orogenesis). The theory being discussed during his time was the "Contraction theory" which suggested that the planet was once a molten ball and in the process of cooling the surface cracked and folded up on itself. The big problem with this idea was that all mountain ranges should be approximately the same age, and this was known not to be true. Wegener's explanation was that as the continents moved, the leading edge of the continent would encounter resistance and thus compress and fold upwards forming mountains near the leading edges of the drifting continents. The Sierra Nevada Mountains on the Pacific coast of North America and the Andes on the coast of South America were cited.
There are volcanoes happens are hidden because it occurring under the oceans, furthermore, Also, many of them happen in the forest. In contrast, the earthquake occurs and happens in any place randomly. It happens in the oceans and in the continents. The source of the earthquakes is the melt area, the first layer under the surface of the ground. Second, the process of the two natural events is different than each others.
There was little cloud cover to protect the land from the sun or to provide moisture from rain. Also the high pressure equatorial belts and rain shadow effect kept the area dry. Therefore the land became loose and dry and blew away with the winds, spreading over large surfaces of area creating deserts.Deserts are usually found 15 and 30 degrees North and South of the Equator. They generally lie on the Western side of land masses and are affected by cold ocean currents. Examples of Hot Desert Biomes are the Sahara Desert covering most of South Africa, one country being Sudan, and the Namib Desert in Namibia.
