Yes, it does. It is not constant.
It didn't. The ozone layer permitted plants and animals to move from the deep water to the water's surface, and eventually to land.
Ozone layer contains ozone in it. Therefore, it is named so.
Earth has a layer of ozone. It is present as the ozone layer.
Ozone is a layer which protects us. Actually ozone is just a gas, ozone layer is the layer.
the ozone layer is the the part of the atmosphere that screens out harmful radiation from the sun.
Yes, ozone layer gets colder as you move forward. This is the sign of ozone layer in atmosphere.
CFCs release chlorine and fluorine move to the ozone layer. There these elements react with ozone to form compounds and the ozone layer is depleted.
Winds and diffusion.
It didn't. The ozone layer permitted plants and animals to move from the deep water to the water's surface, and eventually to land.
Ozone is the only compound present in ozone layer. Westerly winds are the ones that move along.
The ozone layer is just a layer of gas, so while the ozone might get "stirred up" a bit, it does not form a hole. An ozone hole is not a physical hole; it's only an area in the ozone layer where the ozone levels are very low because of decomposition by chemicals. Consider this: If you move your hand through the air, does it leave a vacuum behind? No. The air around it fills in the space almost instantly. Same thing with the spacecraft going through the ozone layer.
Ozone layer contains ozone in it. Therefore, it is named so.
Ozone layer is formed of ozone. It is a gas.
Earth has a layer of ozone. It is present as the ozone layer.
damage to ozone layer is called ozone depletion. It is thinning of ozone layer.
Ozone is a layer which protects us. Actually ozone is just a gas, ozone layer is the layer.
The layer of gases that surround the atmosphere is ozone. It is present as the ozone layer.
