yes deforestation is also one of the main reason in formation of deserts some more reasons WEATHERING processes as large variations in temperature between day and night put strains on the ROCKS, which consequently break in pieces. Although rain seldom OCCURS in deserts, there are OCCASIONAL downpours that can result in flash FLOODS.

Ozone depletionMan-made compounds such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) and halons destroy ozone in the upper atmosphere (stratosphere). The stratospheric ozone layer makes life possible by shielding the earth from harmful ultraviolet (UV-B) rays generated from the sun. Decreased concentration of stratospheric ozone allows increased amounts of UV-B to reach the earth's surface.Stratospheric ozone loss can result in potential harm to human health and the environment, including:increased incidence of skin cancer and cataractsimmune system system damagedamage to terrestrial and aquatic plant lifeincreased formation of ground-level ozone (smog)Most stratospheric ozone depletion is caused when chlorine or bromine reacts with ozone. Most of the chlorine entering the stratosphere is from man-made sources (84%), such as CFCs and HCFCs with the remaining 16% from natural sources, such as the ocean and volcanoes. About half of bromine entering the stratosphere is from man-made sources, mostly Halons.Climate changeWhile acting to destroy ozone, CFCs and HCFCs also act to trap heat in the lower atmosphere, causing the earth to warm and climate and weather to change. HFCs, which originally were developed to REPLACE CFCs and HCFCs, also absorb and trap infrared radiation or heat in the lower atmosphere of the earth. HFCs, CFCs and HFCs are a subset of a larger group of climate changing gases called greenhouse gases (GHGs). Taken together greenhouse gases are EXPECTED to warm the planet by 2.5 to 8 degrees Fahrenheit by the end of century.HFCs, CFCs and HFCs contribute an estimated 11.5% to present-day effect of GHGs on climate and climate change. Some effects of global climate change include:Rising sea levelsLocal natural species extinctions and habitat lossMore frequent heavy rainfall and floodingHigh heat stress in summerIncreasing health risk from insect and water-borne diseasesThe production of CFCs in the United Stated or their import was prohibited as of January 1, 1996. Use of CFCs is restricted to equipment PLACED into use prior to 1996. The production or import of HCFC-22 and HCFC-142b for use in new units or applications was banned in the US as of January 1, 2010, although production and import for use in existing equipment is allowed through 2019. The production or import of HCFC-141b for any purpose were prohibited as of January 1, 2004.Most HFC uses in new units or applications are being phased out under USEPA Rules over a staggered schedule that begins in 2016 and stretches through 2024. Under these Rules, most HFC uses in polyurethane and other foams and in new retail food refrigerated cases will be phased out between January 1, 2016 and January 1 2020. Use of HFCs in MOBILE air conditioning will end with Model Year 2020, while prohibitions on HFC use in new fire suppression systems, cold storage, residential refrigeration, and building chillers go into place on January 1 of 2018, 2021, 2023 and 2024, respectively.Use of HFCs in existing equipment is unaffected by EPA regulations. Minnesota has an estimated 12 million residential appliances and car air conditioners that contain a total of about 13,000 tons of CFCs, HCFCs and HFCs.Regulations are in place to HELP prevent the release of CFCs, HCFCs and HFCs into the environment. In addition to the various production bans, servicers and disposers of appliances and motor vehicle air conditioners are required to obtain technician certification, proper refrigerant recovery or recycling equipment, and keep records.Explanation:hope you are satisfied with the answer

An electric fuse is an electric device which interrupts the flow of CURRENT in an electric circuit. ... A fuse is USUALLY a SHORT PIECE of wire. The fuse is made up of a material which has high resistivity and low MELTING point, so that it melts down due to overheating of the wire during high current flow.

______, the amount of DISSOLVED oxygen is reduced in the WATER body.Elevation- the amount of oxygen in elevation increases. Since streams get MUCH of their oxygen from the atmosphere, streams at higher elevations will GENERALLY have less oxygen. Salinity (saltiness)- Salty water holds less oxygen than fresh water. Temperature- cold water holds more dissolved oxygen than WARM water.

he table is a circular table and so the FRICTIONAL force is EQUIVALENT to the centripetal force of the table as it moving with a constant angular VELOCITY.A centripetal force is a force that makes a body follow a curved path. Its direction is always orthogonal to the velocity of the body and TOWARDS the fixed point of the instantaneous center of curvature of the path.The equation for centripetal force using angular velocity is:F =mω^2Rwhere, m = mass, ω = angular velocity, and R = RADIUS of path of motion.Hence, the friction force between block and table is mω^2R.

tion:FRIENDSHIP is the most treasurable relation in one’s life. A friendship develops between people when they share the same wavelength with each other. A person cannot survive on own without any friends in life. Friends are a trust worthy person with whom we share all our secrets. They stand with us in our difficult times.A true friend never DESERTS us when we are in need for their company. There is a saying that goes ” You are known by your company, the people you move with”. Therefore, being cautious in choosing real friends are vital in one’s life. It may become easy to fall as a prey to bad people and get spoiled.True friends always guide us in the right PATH. At the same time it BECOMES our responsibility to be loyal and helpful to our friends.
