Gulf Coast. The formation of the barrier islands is not fully understood. There have been many theories about their formation‚ but the current one states that barrier islands were formed about 18‚000 years ago at the end of the last Ice Age. As the glaciers melted‚ the sea level started to rise and flooded areas behind the beach ridges at that time. The rising waters carried sediments from those beach ridges and deposited them along shallow areas just off the new coast lines. Waves and currents continued

Global Warming By Abhijit Naik/30/11/2011 Global warming is one of the most serious environmental issues threatening the very existence of various plants and animal species on the planet. Over the last 100 years‚ the global near-surface temperatures has increased by 0.32SF as a result of various natural as well as anthropogenic causes of global warming. That being said‚ one also needs to take into consideration that the natural causes of global warming play a crucial role in stabilizing 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

oblivious to the consequences that may come. Wetlands are essential resources for the environment. Wetlands provide homes for many animals especially for birds and fishes; it also provides benefits for humans such as flood prevention‚ protection from erosion‚ and provides food. Four hundred years ago around 220 million acres of wetland existed across the 48 states in America by the year 1993‚ 110 million acres remain 50 percent of wetlands have been destroyed due to various reasons some include drainage

Weathering- the physical and chemical disintegration of rock that is exposed to the atmosphere. Mass-wasting- the short-distance down slope movement of weathered rock under the direct influence of gravity; also called mass movement. Erosion- detachment‚ removal‚ and transportation of fragmented rock material. 3. Openings in the surface and
