Hydrologic Cycle
The field of Hydrology is primarily concerned with how water falls from the atmosphere, to the Earth; rolls downhill via gravity eventually out to the ocean and then back up into the atmosphere starting all over again. Biological processes of animals and plants have evolved over millions of years to adapt to, and depend on, when the right amount of water is available (Lutgens & Tarbuck, 2014, p. 83). The hydrologic cycle goes through many processes; This continuous cycle of water releases up into the air, forms into a cloud, rains down to the Earth and then evaporates again, repeating this continuous process. Some amount of groundwater also releases back into ...view middle of the document...

Glacial Landscape
A glacier is made up of a mass snow fall over many years that become solid ice. Glaciers can move in a downhill direction and flow on oceans and land. Glaciers are not landforms however; the action of glaciers creates landforms. It is a process known as glaciation, which is the slow wearing of the Earth surfaces through the action of wind and water. Because glaciers can move, they create landforms by picking up rocky earth creating even more fantastically natural features.
There are many types of features that these glacier landforms leave behind; cirque, arête, col, horn, tarn, paternoster lake, hanging valley, v and u shaped valleys, fjord, and truncated spurs.
Several winters ago, my family and I traveled the Rocky Mountain National Park in Colorado. The magnificent views capture obvious glacial landmarks many of which are "U-shaped" valleys, and Rocky Mountain National Park is full of them. The downhill weight and pressure of the glacier tends to "flatten" or broaden the valley -- hence, it creates the characteristic U-shape (Network of Conservation Educators & Practitioners [NCEP], n.d., p. 5). We were also able to hike to the summit of Flattop Mountain which provided an amazing view of what is called a bergschrund glacier. A bergschrund is a glacier that pulls away from the headwall forming a crevasse. In winter, it is often filled...

This supports the continental drift theory because it shows that although once one super continent, the convection currents pushed the continents apart and they began moving across the Earth. Some landforms also help support the plate tectonic theory such as Fold Mountains and rift valleys. Fold Mountains form on compressional plate margins (where two

1542 words - 7 pages mountainous areas where ice can survive all year (Marshak, 2009). Glacial landscapes involve a variety of sediment types that have been collected and deposited through the glacier movement (Stephenson et al, 1988). As glaciers flow, the erosion and deposition of collected sediments can create new landforms, some unique to the glacier type of either mountainous or continental (Marshak, 2009). As well as this, glaciation is accompanied with other

Congenital moraines can be a great deal larger and a good example of this is the Bloomington Moraine in Illinois, which is more than 300 km long. There are several other landforms that
