The phase of matter where particles at extremely high temperatures become ionized.

Plasma

Explanation:

There are four states of matter

Solid state : It is a state in which the particles are closely packed and does not have any space between them. This state has a definite shape and volume.

Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. This state has a definite volume but does not have a fixed shape.

Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them.This state has indefinite volume as well as shape.

Plasma is the state of matter in which the gas is present in ionized form and is at high temperatures. Thus due to the presence of charged particles, they allow electric current to pass through them and are good conductors of electricity.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
