Answer:Like other oceanic areas, the water column in the Indian Ocean also contains mid-depth O2 concentration minima, maintained by a combination of relatively high O2 demand by microbes that decompose organic matter sinking from the surface, and restricted O2 supply as a result of sluggish deep-water circulation and mixing.

Answer:
Global Sound (SGS) is the digital archive project of the Smithsonian Center for Folklife and Cultural Heritage (SCFCH), launched in 2005 by Smithsonian Folkways, the nonprofit record label of the Smithsonian Institution.
The statement is - True.
The solvent do contains chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) which evaporate and enter the atmosphere. Because they are very light, the CFC and HCFC manage to get very high into the atmosphere, reaching the ozone layer in the stratosphere. They are actually the two substances that are the most damaging to ozone layer, as once they get in touch with it, they break down its structure, thus creating the ozone holes.
The ozone is crucial for the survival of the living organisms on the Earth as it is the layer that manages to stop most of the ultraviolet rays form the Sun to reach the surface. Because of that, these two substances have to be replaced quickly as the ozone layer is becoming more and more damaged, and that can eventually lead to a tragedy.
A globular cluster is a collection of stars in the form of a sphere that orbits a galactic core. Global clusters are generally tightly bound by gravity, making the stellar density higher toward the center, and giving them their spherical shapes. Globular clusters are usually found in the halo of a galaxy.
The fact that the gravitational pull of a globular cluster is rather weak means that a single supernova explosion can blow the interstellar gas out of a globular cluster. This would mean that the gas left is not dense enough to form new stars. After the first generation, globular clusters cease to form new stars because they lack material due to their deficiency in heavy elements.
Sedimentary rocks because any rock would wear down and become sedementary.
