Specific objectives 1. Define crustal plates A crustal plate is a rigid layer of the Earth’s crust that is believed to drift slowly. 2. Name and locate the Caribbean adjacent plates. Plates adjacent to the Caribbean plate are South American plate which is located south of the Caribbean plate‚ North American plate which is located north of the Caribbean plate‚ Nazca plate which is locate west of the Caribbean plate and the Cocoa plate which is located south west of the Caribbean plate. 3. Distinguish

ENVIRONMENTAL PROBLEMS BIODIVERSITY LOSS Biodiversity - refers to the number and size of populations in a community; variability of species in an area In general‚ there are three categorical levels of biodiversity: 1. Genetic biodiversity - involves populations‚ individuals‚ chromosomes‚ genes and nucleotides 2. Taxonomic biodiversity - include kingdoms‚ phyla‚ orders‚ families‚ genera‚ species‚ subspecies and populations - for practical reasons‚

Premium Sediment Bald Eagle Forest
The layers are composed of sediments such as sand‚ silt‚ and clay that have been cemented to form sedimentary rocks. The sedimentary rocks in this area were deposited during the late Cretaceous Period which was 67 to 75 million years ago. Deposition and erosion are geologic process that created the formation of The Badlands. Some of the formations that took place at the Badlands National Park are: • The Sharp formation is light in color and deposited by wind and water in the dry and cool climate

is a meander‚ this is to do with the river trying to take the path with the least resistance and occurs inside the rivers channel so does not require flooding to create them‚ yet despite this when there is high discharge it increases the rate of erosion and the meander is created quicker and creates centripetal force towards the banks which causes undercutting to create the outer concave

process mainly at work is vertical erosion. Further it has got a lot of interlocking spurs. There is less lateral erosion taking place. So the bed load is composed of bigger rock particles with irregular size. When it reaches the middle course‚ the river is quite near to its base level. So it uses its surplus energy to erode sideways. Hence the processes like abrasion‚ attrition‚ hydraulic action smoothens the rough edges making the shape circular. The lateral erosion and transportation may give rise

geometric organization. These geometries and their bounding surfaces are closely associated with changes in accommodation (space available for sediments to fill). Thus the simple sequence stratigraphic framework is based on surfaces of erosion and non-deposition (sequence boundaries)‚ and flooding (trangressive surfaces and/or maximum flooding surfaces [mfs]). In addition there is an implicit but sometimes unstated connection between the external and internal surfaces of a sequence and base level

Beach Erosion on Long Beach Island and the Grand Strand Earth 111 ------------------------------------------------- Abstract Long Beach Island is a barrier island located approximately one mile off of the southern coast of New Jersey. The island in some areas is only a half-mile wide‚ with some areas‚ which are even narrower. Therefore‚ coastal erosion and flooding are both major concerns for the residents. Most of the island’s eighteen miles of beaches have experienced significant damage

Past the Puget Sound lie the Olympic Mountains. Seattle owes its specific structure due to glacial scouring and deposition and tectonic activity‚ subsequently modified by landsliding‚ stream erosion and deposition‚ and human activity. Geological hazards Seattle is threatened by several geological hazards‚ such as earthquakes‚ flooding‚ volcanos and landslides and shore erosion. Perhaps one of the most prominent hazards to Seattle is the Massive volcano‚ MT. Rainier‚ which lies 54 miles southeast
