Siberian traps refers to the moment when the volcanoes of Siberia expelled a large amount of CO2 and HCl gases that are highly toxic and that promoted a mass extinction, that is, it caused the death of several living beings in a short period of time. This happened over 250 years ago and was caused by the steps:
It all started when volcanoes expelled large amounts of carbon dioxide into the atmosphere, which contaminated the atmosphere and caused a rise in temperature, creating strong global warming. This caused a great warming of the surface of the seas, which caused them to evaporate in great intensity and lose large amounts of oxygen and become anaerobic environments, conducive to the growth of bacteria producing hydrogen sulfide, which is a very toxic gas. This gas was released into the atmosphere, killing several living beings intoxicated with the contaminated air.
Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
