Sunlight can pass through atmosphere. But not the part containing UV rays.
Ozone
The sky is actually black but the reflections of sunlight on the sea causes it to appear blue. There are also other causes of the sky colouration. Dust in the upper atmosphere can make it turn red or purple. The last few seconds of the sunset when passing through the waves of the ocean can make it appear green. A grey sky can be from storm clouds. A white sky can be ice in the upper atmosphere.
day and night
The speed of light is constant in a given medium.
They reflect sunlight into the upper atmosphere to counteract global warming. It would however delay the recovery of the ozone by decades.
The ozone layer is a part of the Earth's stratosphere and is not physically damaged or removed by rockets passing through it. However, some rockets emit gases that can contribute to ozone depletion, such as chlorofluorocarbons (CFCs) or other ozone-depleting substances. These substances can accumulate over time and have a long-term impact on the ozone layer health.
it is the ozone layer in the atmosphere because it is what keeps the atmosphere in check of what is happening in the atmosphere.
The planet is heated from the surface upwards, so the higher you go, the farther you are from the heated surface and thus, the cooler it gets. Even though sunlight passes through the upper parts of the atmosphere, it doesn't warm them as much as it warms the surface.
It is a good thing for the ozone to be in the upper atmosphere. It is due to the fact that ozone in upper atmosphere forms the ozone layer.
The ozone is formed in the upper atmosphere due to the UV radiations. These radiations help to create ozone due to the high energy they posses.
it is the ozone layer in the atmosphere because it is what keeps the atmosphere in check of what is happening in the atmosphere.
Ultraviolet radiation from the sun passes through the atmosphere and reacts with plants, animals and the soil and water - unless it is absorbed by chemical reactions that it initiates in the upper atmosphere.
