The ozone layer is a layer of ozone gas. The layer is present in stratosphere. It helps in protecting earth.
CFC chemical
The CFC's form a hole in ozone layer. They are highly reactive with ozone.
A hole is formed in the ozone by CFC's. It is not actually a hole but less concentration.
The ozone hole is formed due to the ozone depleting substances. These substances contain CFC which deplete the ozone layer.
The ozone hole in formed in the stratosphere region of the atmosphere. It is because most of the ozone is present in that layer.
The ozone hole forms over Antarctica. It is because of low temperature.
The main reason behind ozone hole is the reaction of the chlorine molecules from CFC's. These molecules initiate a chain reaction which then destroy the ozone molecules to form the ozone hole.
The ozone hole forms in late winters. It is because depletion happens in cold weather.

The name of the hole is ozone hole. It is the thinning of ozone layer.
Unrelated. Ozone holes form annually at each pole.
The Space Station doesn't form holes in the Ozone. Pollution on Planet Earth does that.
Ozone hole allowed to make many important decision. Main was to limit the production of CFC's.
