UV light does interact with earth surface. But only in areas where there is absence of ozone layer.
The ozone interacts with UV. Since UV is coming from sun, it interacts with ozone.
It means that either the Sun is not making as much UV light, there is something between the Sun and the Earth absorbing it, there is an increase temperature where the ozone is located (increasing its decay rate), or compounds that destroy / consume ozone are increasing. Additional UV radiation can get through to the surface of the Earth if diminshed UV light arriving at the Earth is *not* the cause of ozone loss.
The nitrogen and oxygen protects Earth's surface from UV-C and more energetic radiation. The ozone uniquely protect Earth's surface from UV-B.
No, Earth's atmosphere does not block all UV radiation from space. It does absorb a portion of the UV radiation, particularly the most harmful UV-C rays. However, UV-A and UV-B rays are able to penetrate the atmosphere to some extent and reach the Earth's surface.
The ozone hole allows some radiations to reach the earth's surface. These radiations are high energy UV radiations.

Ozone in the high atmosphere absorbs light in the UV wavelengths - thus protecting plants and animals (and people) down on the surface of the earth from the effects of excessive UV exposure.
UV light are of threee types: UV A UV B UV C( it doesn't reach earth's surface). UVA and UVB rays can damage your skin causing sun burns, tanning and even skin cancer.

When UV reaches earth, it interacts with ozone. It both creates and depletes ozone.

Two consequences there are if UV-B reaches the earth. It can cause skin cancer in beings and global warming too.

It partially absorbs it
UV and infra-red rays are deflected by the earth.
Ozone layer. I think it's the UV light that the ozone stops. I think X rays are prevented from reaching Earth's surface by the lower atmosphere.
