Answer:

Two possible reasons for the massive extinction at the end of the Paleozoic Era are an asteroid collision and massive volcanic eruptions.

Explanation:

The massive extinction that occurred at the end of the Paleozoic Era is the biggest extinction from what is known so far. The majority of the species died out, and whole families of animals and plants were wiped out of the face of the Earth. It was only small and highly adaptable organisms that managed to survive and give rise to the later life-forms.

The two possible reasons for this massive extinction are an asteroid impact and massive volcanic eruptions. An asteroid collision would have created drastic changes in a matter of minutes and hours, with effects lasting for a long period of time, thus eliminating the majority of the life. Massive volcanic eruptions, with the Siberian super-volcano being the prime candidate, may have caused enormous amounts of carbon dioxide and sulfur dioxide to end up in the atmosphere, thus rapidly changing the living conditions on the planet.

What is the importance of the atmosphere for man​
Gnom [1K]
The atmosphere is important for many reasons. Before we talk about why it is important we should define what the atmosphere is. The atmosphere is the layer of air that surrounds a planet. Earth has an atmosphere that is just right for humans, animals, and plants to live in. The gases in the atmosphere act like a blanket keeping our planet warm plus the atmosphere contains oxygen something we (humans and animals) all need to breathe.

Many planets in our solar system have a atmosphere. Venus for example has such a thick atmosphere most of the sun's energy gets trapped making the surface of Venus 864 degrees Fahrenheit! That is hotter than an oven! Mars also has an atmosphere but it is too thin making the surface of Mars -80 degrees Fahrenheit! Plus the atmospheres of Venus and Mars do not contain the oxygen we all need to breathe.

Our atmosphere allows just enough of the sun's energy back into space so that we do not get to hot like Venus or too cold like Mars. If Earth had no atmosphere, apart from having no air to breathe, the surface of the Earth would be 0 degrees Fahrenheit.

These are just two of the reasons why are atmosphere is important. The atmosphere contains the warmth we all need to survive, the oxygen we all breathe, and carries the rain we all need. Without our atmosphere life as we know it would cease to exist.
