attacked‚ decomposed‚ and eroded by various chemical and physical surface processes. Weathering is the first step for a number of other geomorphic and biogeochemical processes. The products of weathering are a major source of sediments for erosion and deposition. Many types of sedimentary rocks are composed of particles that have been weathered‚ eroded‚ transported‚ and terminally deposited in basins. Weathering also contributes to the formation of soil by providing mineral particles like sand‚ silt

(detritus) to settle and accumulate or minerals to precipitate from a solution. Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited‚ sediment was formed by weathering and erosion in a source area‚ and then transported to the place of deposition by water‚ wind‚ mass movement or glaciers which are called agents of denudation. The sedimentary rock cover of the continents of the Earth’s crust is extensive‚ but

Atmospheric Issues Anita Curcio SCI / 275 04/27/2013 Maria West Atmospheric Issues "Acid rain" is a broad term referring to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. The precursors‚ or chemical forerunners‚ of acid rain formation result from both natural sources‚ such as volcanoes and decaying vegetation‚ and man-made sources‚ primarily emissions of sulfur dioxide (SO2) and nitrogen oxides

Hurricane a Natural Ocean Disaster The ocean has been shaping our land as we know it for millions of years. It is a beautiful part of our Earth‚ nonetheless it has the greatest influence on some of the deadliest natural disasters to us and these disasters alter our shorelines and lives as we know it. Hurricanes are among the deadliest natural disasters known‚ those that live near the Gulf or eastern coast know of and prepare for the damages it can cause. Many have heard of the devastation hurricanes
