Although deserts and glaciers appear very different, they have a common link: extreme climates. The extreme temperatures these regions face has a significant impact on both the desert and glacial landscape. Extreme changes in temperatures can be caused by human activity, environmental changes, or a combination of both. Climate changes can cause less rainfall in desert areas which can cause water tables to become lower and more salt appears in top-soil and water. The wind can become arid and dry and cause desert like conditions in non-desert areas, thus expanding the size of a desert.
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.
Not only can sinking air not produce rain, but when it reaches the ground it absorbs water from the soil and vegetation, creating even more arid conditions. We find deserts where this air descends. In fact, at about 30° North, hold the Sahara, the
Winds push horizontally against the sea surface and drive ocean current patterns. Interactions between the ocean and atmosphere can also produce phenomena such as El Niño which occur every 2 to 6 years. Deep ocean circulation of cold water from the poles towards the equator and movement of warm water from the equator back towards the poles. Without this movement the poles would be colder and the equator warmer. The oceans play an important role in determining the atmospheric concentration of CO2.
), the warming of climate change as well as industrialization of people. None of these impacts are possible without one key human event and that is globalization. Globalization is the way in which people are able to make connections throughout the world and change different areas depending one who has the greatest amount of influence. Without globalization there wouldn’t be as much pressure on the melting of glaciers. Glacial melt is a direct impact of human ways through globalization and a borderless world.
Another source is the release of salts as rocks weather. Another possible cause could be ancient drainage basins or inland seas that evaporated during dry periods, leaving behind salt deposits that still remain today making that land infertile and useless for any agricultural purpose. However, rising groundwater levels are bringing previously stored undisturbed salt to the surface where it affects soils, streams, vegetation and farming. Rising groundwater levels can be caused in two different ways. The first is the naturally changing Australian landscape.
What the Mountain Environment is like? (Weather) The climate is not the same throughout the biome (community) because there are places nearer to the equator than others. The Andes are separated into three natural regions: the southern, central, and northern regions. In the northern region, it is hotter because it is closest to the equator. There are rain forests in this region, due to the more humid, rainy climate.
Furthermore, more and more ice from glaciers and polar ice caps is melting during summer, and not being balanced back out in winter months. During the summer, these formations will naturally melt a little, however, due to the increase in temperatures, more of the ice is melting during this time, and less is being replenished as snow over these ice formations during the winter months, in which
The Earth’s average temperature has risen 0.6°C, while areas in the Arctic have risen up to 3.0°C in the last 20th century (Gardiner, 2008). Increasing temperatures have already caused changes in the Arctic such as; sea ice covering the Arctic has decreased in area and thickness due to melting of ice and snow, the warming of permafrost, snow cover area has also decreased, and ice on the rivers will freeze later during fall and break up earlier in spring. But why are these Polar Regions more vulnerable to climate change? This is due to the light colour of snow and ice and high albedo, which reflects the solar energy back into space. Due to the increase in greenhouse gases less solar energy is reflected back into space and more solar radiation is absorbed by the Earth causing the increase in ice and snow melting (Main & Ahlenius, 2011).
Second, the process of the two natural events is different than each others. The volcano usually happens and forms near the plates boundaries of the ground. First, the crust is moving a little bit and causing melt because of decreasing the
