Chemical
The chemical compound responsible for the depletion of the ozone layer is chlorofluorocarbons (CFCs) and other halocarbons. These compounds contain chlorine and bromine atoms that can break down ozone molecules in the stratosphere.
The ozone layer is very important to climate change. It's depletion can cause climate adversity.
Nope... sanding a table top is a physical change
The process of cooking eggs to make an omelette involves a physical change. The heat causes the proteins in the eggs to denature and coagulate, resulting in a change in texture and color, but the chemical composition of the eggs remains the same.
Silver tarnishing is a chemical change. It occurs when silver reacts with sulfur compounds in the air to form a layer of silver sulfide on the surface. This chemical reaction changes the composition of the silver, resulting in the tarnished appearance.
Ozone layer and it's depletion is pure chemistry. It's formation and depletion is due to the chemical bonds.
Depletion of ozone alters ecosystem. This then alters the climate change.

It's a chemical change. A thin layer of silver on the surface reacts with oxygen in the air - to form silver oxide.
I guess it could be chemical, but really- it's a physical change
Ozone layer has undergone various changes. These are the depletion of ozone molecules.
chemical change :-)
CFC's are responsible. They react with ozone to deplete it.
Paneling a room, or in other words applying wood panels to the walls of a room in order to modify the look and feel of the room, would be a physical change and not a chemical change because you are changing the physical properties of the room and not the chemical composition of the room.
Sanding rust off a bike is a physical change because it does not alter the chemical composition of the rust or the metal underneath. It only changes the physical appearance by removing the rust layer mechanically through abrasion.
Making toast is a chemical reaction because you can't change it back into untoasted bread.The drying of the bread is physical but the actual caramelization or darkening of the outer bread layer is a chemical change. The outer edges of the bread are beginning to char. Generally, a color change is an indicator of a chemical change.
