What causes the ozone hole to grow?

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), referred to as ozone-depleting substances (ODS).

How can we stop the ozone hole from getting bigger?

How can we protect the ozone layer?

  1. Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process.
  2. Minimize the use of cars.
  3. Do not use cleaning products that are harmful to the environment and to us.
  4. Buy local products.

What is the cause and effect of ozone hole on the environment?

The destruction of the ozone layer is primarily caused when the amount of gases that contain chlorine begins to increase in the environment. As these gases rise upwards, they are exposed to UV light. These affect the atoms of ozone and cause ozone depletion.

What causes the ozone layer to be thinner?

The ozone layer is getting thinner. Chemicals called chlorofluorocarbons (CFCs) are a reason we have a thinning ozone layer. A chlorofluorocarbon (CFC) is a molecule that contains the elements carbon, chlorine, and fluorine. But the CFCs start eating away at the ozone layer once they get blown into the stratosphere.

Is the sun in Australia stronger?

UV radiation is the strongest around noon; the sun gives off its strongest light from 10:00 a.m. to 3:00 p.m. When it comes to seasons, the sun is strongest during the summer, as this is when Australia is closer to the sun (due to the earth’s orbit).

What is the function of ozone which is present in the upper level of atmosphere?

Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation.

What are the causes of ozone?

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).
