What atoms are in the stratosphere?

In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone.

Why are chlorine atoms so destructive to atmospheric ozone?

When the chlorine atom breaks apart it travels freely around the atmosphere trying to find a partner to bond with. It often meets with ozone molecules, or oxygen atoms, and steals oxygen atoms from others. This causes a chain reaction and causes chlorine atoms to steal ozone atoms for a very long time.

What happens when chlorine reacts with ozone?

When present together in the stratosphere, chlorine (Cl) and ozone quickly react to produce chlorine oxide. Bromine can also act as a catalyst to destroy stratospheric ozone.

What can fly in the stratosphere?

PSCs are also called nacreous clouds. Air is roughly a thousand times thinner at the top of the stratosphere than it is at sea level. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere.

What is the strongest evidence that Hcfcs are in the stratosphere?

What is the strongest evidence that CFCs are in the stratosphere? Measurements of CFCs in air samples from the stratosphere. What compounds have the highest ozone depletion potential? May be fined.

Why CFCs destroy the ozone layer?

An ozone hole is really not a hole but rather a thinning of the ozone layer in the stratosphere that changes seasonally. Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules.
