Physical Geology - Essay Example The landscapes we see around us have many different and varying features, many of which have been fashioned by a number of external forces. Erosion is probably the major force in this respect and it can come from a number of sources, such as wind, water and ice. While these sources can be seen to be unique, in fact in the majority of cases they usually combine within the erosion process that shapes our landscapes. Wind is forceful creator of particular land features, especially in areas where deserts exist, normally close to the equator. In this instance as the warm air rises, forming clouds, the winds blow these away from the equator, both north and south, leaving a dryer condition. As a result, these areas receive significantly reduced rainfall, limiting the amount of vegetation, which would bind the earth’s surface together. The wind also carries particles of plants and rocks with it to create a build up of vegetation and chemical deposits in other areas. The power of the w ind, for example in the form of hurricanes, can have a significant effect on the landscape, as well as destroying human habitats.
