Introduction Metamorphism is defined as the mineralogical‚ chemical and structural adjustments in solid rocks to physical and chemical conditions which have been imposed due to changes in pressure and temperature or both. Metamorphism occurs below the surface zones of weathering and cementation. Conditions of metamorphism differ from the conditions under which the rocks in question were originally formed. Metamorphism produced as a result of the progressive increase in temperature and pressure‚

fish habitat characteristics include sediment type‚ type of bottoms (sand‚ silly and clay)‚ structures underlying the water surface‚ and aquatic community structures. These habitats and environments are essential for fish and a fisheries health in an ecosystem. Sediment in relation to essential fish habitat is a place where essential habitat begins; primaryproductivity takes place here because benthic photosynthetic algae provide food‚ nutrients and help stabilize the sediment from erosion in aquatic environments

Excess amount of sediments -many large rivers along the coast of the ecoregion carry vital nutrients and sediments that are important to plankton‚ mangroves‚ and seagrass beds. 2. Climate change and its serious impacts -changes to the coastlines caused by human activity have exacerbated the effects of climate change

for creationism has been discredited throughout the years by ‘simple’‚ evolutionary explanations‚ but neither evolutionists or creationist have the closest thing to a proof. The first evidence for creation is the fact that there is very little sediment‚ or mud‚ on the sea floor. According to many evolutionist the ocean has been around for three billion years. On the other hand creationists think it has only been here for about 3‚000. Every year

The New Madrid Fault Zone History The largest earthquake sequence the United States has ever experienced happened east of the Rocky Mountains starting out in Northeast Arkansas on December 16‚ 1811. On the Richter scale‚ it was ~7.7 and five hours later AK experienced an aftershock of a magnitude of ~7.0. A little over a month later on January 23‚ 1812 New Madrid‚ MO experienced an earthquake with a magnitude of ~7.5‚ and again on February 7‚ 1812 reaching a magnitude of ~7.7. By March 15

expression It has been documented that there are facies tracts from past basinal marine all the way to shallow marine as well as nonmarine in this area. In addition to this‚ the oldest confirmed Mesozoic sediments classified as marine in the province of the basin also include basinal facies Sediments in the Upper Jurassic comprise a placid mixture of carbonates and clastics (Winker & Buffer‚ 1988). Structural deformation of the Upper Jurassic is studied through seismic profiles and has been said (Winker
