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 is a natural process in which rocks or soil are moved from one location to another by wind or water. Material may move through erosion for distances ranging from a few feet to thousands of miles. Erosion often is most noticeable along shorelines, but it occurs in a variety of areas throughout the world.Full Answer >
Soil erosion is caused when elements such as wind and rain remove surface soil. The eroded soil is then carried away and deposited by the wind or rain.Full Answer >
Although both are methods by which liquid water transitions into a gas, evaporation describes the process in which heat changes standing water into water vapor, while transpiration refers to the process plants undertake that draws water from the ground and releases it into the air.Full Answer >
Avalanches occur when masses of snow, often with ice and debris, slide down mountain sides. They are triggered by overloading, snow pack conditions, slope angle, vibration and temperature. They gain speed and power as they draw nearer to the bottom of the slope.Full Answer >
