geologically important - showing characteristics of a specific tectonic environment 2. allowing tectonic reconstitutions II. The second type is sedimentary rock which is formed by small particles or sediments. A. Formation 1.sediments - sand‚ mud‚ dead sea animals‚ weathered rock 2. sediments deposited in layers & become solid rock over millions of years as squeezed by the weight of other deposits B. Importance 1. covering three quarters of the mass of continents 2. important resources

energy and the sediment trapped behind the seawall often decrease the sediment supply near the seawall‚ causing erosion on adjacent beaches. Therefore‚ alternatives to these hard structures are strongly encouraged and actively sought by the NPS.” Breakwaters -“Dunes not directly disturbed‚ increases area of dry upper beach‚ may allow new fore dunes to stabilize. Unlimited structure life.” -Low maintenance -“Visually intrusive‚ alter upper beach morphology‚ may cause fine sediment‚ seaweed or debris

Special habitats in hydrosphere include bottom sediments‚ biological and non-biological surface‚ and interface (between atmosphere and hydrosphere or lithosphere and hydrosphere). There are at least five factors that affect the hydro-ecosphere: light intensity‚ temperature‚ pressure‚ dissolved gases and

Great Barrier Reef system covers an area of 348 000km2. This makes the reef system larger than the United Kingdom‚ Switzerland and the Netherlands Combined. 3 Sections of the Reef 1. Southern Section The inshore waters are frequently turbid with sediments brought by the river systems and resuspended by wave action generated by the southeast trade winds 2. Central Section The central section extends northward from 21˚30’S to approximately 14˚30’S. The continental shelf and the inshore lagoon become

Key Point • Why does ocean water circulate? • How does the topography of the ocean floor change from a continental margin to the mid-ocean ridge? How are the oceans mapped? • How do ocean waves and breakers form? • How sediments are moved along a shore line and what coastal features are formed? • Be able to recognize both depositional and erosional coastal landforms Why should we study the oceans? • 70% of Earth’s surface • Source for food‚ energy

The Hudson River and PCB Pollution The Hudson River and PCB Pollution The Hudson River is a body of water that stretches for 315 miles from the Adirondack Mountains to the Battery in Manhattan‚ reaching its deepest point of 216 feet in the Highlands near Constitution Island and West Point and reaches its widest point of 3 miles across at Havestraw. This river is one of the most beautiful and scenic of the Tri-State area. Unfortunately‚ it happens to be New York ’s most polluted river. The river

rounded pebble would be a type of particle found in a conglomerate. 2. Salt and other minerals that form when a body of water dries up are called evaporites. 3. Sands are the size of detrital sediments larger than mudstones and smaller than conglomerates and breccias. 4. Coals are chemical sediments formed from trees that lived in coastal swamps. 5. Dynamothermal metamorphism develops from increased heat and pressure in an area of plate convergence. 6. Contact metamorphism takes place

Wayne County Ground Moraine (14‚000 to 24‚000 years old)- Ground Moraines often show up as rolling‚ strangely shaped land covered in grass or other vegetation. They don’t have the sharp ridges of other moraines. A ground moraine is made of sediment that slowly builds up directly underneath a glazier by tiny streams‚ or as the result of a glazier meeting hills and valleys in the natural landscape. When a glazier melts‚ the ground moraine underneath is exposed. Ground moraines are the most common
