What does ozone depletion mean?
ozone depletion, gradual thinning of Earth’s ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities.
What is ozone layer in Filipino?

What is the simple definition of ozone?
Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth’s upper atmosphere. (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad ways.
What causes ozone depletion?
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons).
What is ozone depletion and its effects?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. UV rays also affect plant growth, reducing agricultural productivity.
What is ozone depletion causes and effects?
The main effect of ozone depletion is an increase in UV-B rays reaching the earth’s surface. Causes : chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer. CFCs and halons break down into chlorine and bromine which in turn destroy the ozone layer.
What are the effects of ozone depletion in the Philippines?
Damaging effects of ozone-depleting substances allow increased ultraviolet or UV rays to reach Earth, increasing incidents of skin cancer, eye cataracts, compromised immune systems and harm to agricultural lands and forests.
What is the Tagalog of recycle?
1.) resiklo – [noun] recycle; recycling more… 2.) pagrerecycle – [noun] recycling; the act of recycling more…
What causes ozone?
Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.
Which is most harmful for ozone depletion?
Chlorofluorocarbons (CFCs) and other halogenated ozone-depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.
