Hydrogenous sediments are produced when dissolved minerals solidify by chemically reacting with seawater. Common examples of hydrogenous sediment are evaporites, manganese nodules and oolites.
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
Corrosion leads to the degradation and weakening of the affected material. It is caused by materials reacting with the surrounding elements, such as oxygen or water.Full Answer >
Corrosion is a process by which a chemical reaction eats away at a metal. An example of a chemical reaction that causes corrosion is the oxidation of iron by water in an electrolytic process. The product of this reaction is rust.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 >
Sinkholes are depressions or holes that form on the Earth's surface when the ground below erodes away. Sinkholes often indicate the presence of tunnels or caverns below the ground.Full Answer >
