Model (fig 1)‚ a fluvial model that describes changes in the river channel and flow characteristics between different courses along the river. Based on three factors‚ it is possible to infer information about the processes of river erosion‚ transportation and deposition that occurs along the river. I will use the Bradshaw Model to compare the river at Holford Combe with the characteristics that you would expect to happen and what impact these characteristics have on the formation of landforms along

Carbonate Rocks and Dunham’s Classification Palkowski‚ Daniel N. 245-002 General Geology Dr. Wayne Schlipp 9 December 2007 Abstract The following contains a compendium of research on carbonate rocks. Displayed are a basic description of carbonate rocks‚ depositional environments‚ mineralogy‚ ancient and modern reefs‚ diagenesis‚ facies analysis‚ and classification. Most carbonate rock classification schemes take into account characteristics that may require intensive microscopic

The waves spill over. They are constructive. * The process by which the direction of a wave is changed when it moves in to shallower water. * The energy of water impacting on a cracks and joint. Air is compressed into the space‚ leading to erosion. * When particles of sand or rock further abrade the rock surface. * When the waves wear away at the base of a cliff‚ often forming a notch. * The wearing a way of rocks after they have been removed from the cliff face. * The distance

Valley of Fire and Red Rock Canyon Red Rock Canyon is presently located 5 miles west of Las Vegas‚ Nevada. It is 197‚000 acres within the Mojave Desert. The canyon is one of several in the state with the name Red Rock‚ this one is located on the east side of Spring Mountain‚ the flat land rises to a great colorful escarpment‚ formed along a fault zone (the Keystone Thrust) with several peaks over 8‚000 feet‚ and including huge cliffs and ravines composed of bands of gray Paleozoic carbonates

elevation‚ precipitation‚ and air pollution (Clow‚ & Mast 2003). Studies have shown that air pollution causes higher levels of nitrogen deposition in the Rocky Mountain region‚ which can be a challenge to the local plant community due to the already prevalent lack of variety in vegetation in this region (Burns‚ 2004). Based on this information‚ nitrogen deposition within the Rocky Mountains could be considered a stressor within the alpine biome. The Rocky Mountains‚ which are also known as the

On 4th October 2001‚ I went on geography field trip to Ashdown Forest. We got out of the coach and started to walk towards the river source. Unfortunately due to the lack of weather there wasn’t any water. It was dry rather than muddy. We took some notes of landscape then we started walk towards the waterfall which was also dry. We could see where the drop was and where the hard rock eroded away soft rock. We took some measurement of the fall (width and depth). Secondly we walked toward the V-shaped

Next to water and air‚ soil is most essential to our very existence on the earth. Soils are the basis of support for most life‚ and a source of nutrients for marine life and fresh water. As a natural resource‚ soil is of immense value to man. In the agricultural orient the distribution and density of population have conformed to the persisting patterns of soil fertility and productivity. Soil is basically broken-down rock materials and consists of decomposed rock debris and decayed organic

What is land pollution? Land pollution is the deterioration (destruction) of the earth’s land surfaces‚ often directly or indirectly as a result of man’s activities and their misuse of land resources. It occurs when waste is not disposed off properly‚ or can occur when humans throw chemicals unto the soil in the form of pesticides‚ insecticides and fertilizers during agricultural practices. Exploitation of minerals (mining activities) has also contributed to the destruction of the earth’s surface
