Hydrogenous sediments are produced when dissolved minerals solidify by chemically reacting with seawater. Common examples of hydrogenous sediment are evaporites, manganese nodules and oolites.Know More
Marine sediments are accretions of loose materials transported and deposited on the ocean floor. The different types of marine sediments include hydrogenous, lithogenous, cosmogenous and biogenous. Hydrogenous sediments are valued for their economic importance.
Sedimentation of hydrogenous components may occur where they are deposited, rather than having been transported to the ocean floor. Evaporites are created when ocean water evaporates and crystallizes, which typically occurs in dry, shallow-water aquatic areas.
Halites, gypsum and calcium are primary examples of evaporites. Manganese nodules are mainly composed of iron and manganese oxide, nickel, chromium and cobalt. Oolites are formed from the precipitation of calcium carbonate in seawater.Learn more about Erosion & Weathering
Erosion occurs as a result of wind and water moving across earth and picking up part or all of dirt or rocks. By definition, erosion only requires earth to be moved, but in most cases, rocks or land are also worn down or broken into pieces.Full Answer >
Acid rain contaminates water and soil, killing microbes, insects, fish, and other aquatic wildlife and vegetation. It corrodes stone and metal, and it damages automotive paint. Although contact with acid rain is not directly harmful to people, it can indirectly cause health problems.Full Answer >
Also called a shore platform, a wave-cut notch is a narrow flat area that is normally found at the base of a sea cliff or the shoreline of a sea, lake or bay. It forms by the action of waves hitting against the face of the cliff. Wave-cut notches are mostly obvious during low tides when they become visible as huge, flat rocks.Full Answer >
Wild Again states that deforestation can contribute to soil erosion, flooding and droughts. In many countries, there has been a marked increase of flooding in areas that have experienced deforestation.Full Answer >
