Question

The following lists the steps between the Siberian traps and mass extinction. Choose the answer that puts the steps in the correct order. [1] As hydrogen sulfide accumulated in the ocean, the poisonous gas escaped into the atmosphere. [2] Carbon dioxide in the atmosphere trapped heat, causing global warming. [3] Hydrogen-sulfide producing bacteria thrived in the anaerobic oceans. [4] Mass extinction occurred on the land and in the water due to hydrogen sulfide poisoning. [5] Ocean waters lost oxygen as the oceans warmed up. [6] Volcanoes released mass quantities of carbon dioxide into the atmosphere.

Answer 1

The correct order is: 6, 2, 5, 3, 1, 4

Step-by-step explanation:

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.
