The short answer is: Earth molten iron core!
This on its own is a wrong answer, but looking at the "big picture" you will see why:
The Earth is in actually protected by the magnetosphere, which is a magnetic field radiating out from the north- and south-pole of the globe.
This magnetic field deflects the deadly ray from the sun, also called Solar Wind.
Without it Earth would be as deserted and seemingly lifeless as Mars.
The magnetosphere, is more teardrop shaped, rather than round as the name suggest, with the flat side toward our Sun.
This magnetosphere is actually made in the Earth molten iron core, with the interaction between the layers the friction actually produces a magnetic field, this field stretches 70,000 km out in space toward the sun, and roughly double as long away from the sun.
The ozone layer in the Earth's stratosphere acts as a shield by absorbing a significant amount of the Sun's ultraviolet (UV) radiation. Without this protective layer, UV rays would reach the Earth's surface in much higher levels, causing harm to living organisms and leading to increased rates of skin cancer, cataracts, and other health issues.
Ozone layer protects us. It is present in the stratosphere.
The triatomic form of oxygen that is ozone protects us from the harmful rays of the sun. These rays are called ultraviolet rays and are very harmful for living organisms.
The ozone layer, found in the stratosphere, helps protect the Earth from the harmful effects of ultraviolet (UV) rays from the sun. It absorbs and scatters a significant portion of the UV radiation, reducing the amount that reaches the Earth's surface.
The layer that protects the Earth from ultraviolet rays is called the ozone layer. It is located in the stratosphere and absorbs most of the sun's harmful UV radiation.
The layer of gas that protects the Earth from harmful rays of the sun is the ozone layer. It absorbs most of the sun's ultraviolet (UV) radiation, preventing it from reaching the Earth's surface and causing damage to living organisms.

Ozone protects earth from UV rays. This is present as ozone layer.
Ozone layer protects the earth from UV rays. These are fatal for life on earth.
It protects the Earth from ultraviolet rays or U.V rays.
Ozone layer protects us. It is present in the stratosphere.
Ozone layer protects us. It is present in the stratosphere.
Ozone layer protects us from UV rays. It is present in stratospere.
The thing that protects the earth from ultraviolet rays given off by the sun is called the ozone layer. The ozone now has a large hole in it.
Ozone layer protects us. It does so by blocking UV rays.
The ozone layer of atmosphere protects us from the sun's ultraviolet radiations. This ozone layer is present in the stratospheric region of the earth.
The triatomic form of oxygen that is ozone protects us from the harmful rays of the sun. These rays are called ultraviolet rays and are very harmful for living organisms.
Ozone is the vital gas that protects the earth from the sun's harmful ultraviolet radiations.
