<span>The correct answer is: Chlorofluorocarbons (CFCs)
Explanation: In simple words, CFCs are the chemical compounds made up of the following three elements: 1. Carbon 2. Chlorine 3. Fluorine
When CFCs compounds reach the upper atmosphere, the ultraviolet rays coming from the Sun break those compounds into individual elements, which then react with one of the oxygen atom of the ozone (O3) to form new compounds like chlorine monoxides. That way the ozone molecules get destroyed, resulting into the ozone depletion. Hence, the correct answer is Chlorofluorocarbons (CFCs).</span>
The chlorofluorocarbons (CFCs) were being used in air conditioners, aerosol spray cans, and industrial cleaning products since 1960s. These CFCs are inflammable, but once they are into atmosphere they move to the upper stratosphere and there they enter into a never ending chain reaction thereby releasing chlorine . The free chlorine react with ozone and destroy its molecule.
Answer: Acted on by equal forces in opposite direction
Explanation:
Newton's First Law says that every body continue in its state of rest or constant speed on a straight line unless being acted upon by an external force.
