Answer:
Explanation:
Abyssal plain : very level area of the deep-ocean floor typically lying at the foot of the continental rise G
Guyot: A submerged flat-topped seamount H
Deep-ocean basin: portion of the seafloor between the continental margin and oceanic ridge; comprises 30 percent of Earth's surface C
Continental Volcanic Arc: Mountains are formed in part by igneous activity associated with the subduction of oceanic lithosphere beneath a continent A
Deep-Ocean Trench: Long, relatively narrow crease in the seafloor that forms the deepest parts of the ocean. D
Oceanic Plateau: extensive region of the ocean floor with thick accumulation of pillow basalts and other mafic rock E
Seamounts: An isolated volcanic peak that rises above the deep-ocean floor
Volcanic island arc: A chain of volcanic islands generally located a few hundred kilometers from a tench where active subduction of one oceanic slab beneath another is occuring; some trenches run parallel to an arc shapes row of active volcanoes
Answer: The process of reducing or removing minerals from water is called desalination.
Explanation:
The most commonly involved in this process is seawater, which by its nature contains large amounts of salt. This process makes it possible to remove salt from the water and obtain drinking water. The coastal and island regions often have great difficulty in supplying drinking and process water. As a result, permanent or occasional shortages of water and all the resulting consequences are becoming increasingly frequent.
Furthermore, in the future, due to a possible lack of water, this process could be crucial in supplying humanity with drinking water. Today, some countries (such as Saudi Arabia) that have a water scarcity problem are actively using this technique to supplement the required quantities of water.
