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

Answer:
increases, angle, 10 parsec
Explanation:
d=1/p
d: distance in parsec
p: parallax in arcseconds
One parse is defined as distance at which angle subtended by an astronomical body from earth's equator is one arcsceond.
Answer:
Explanation:
The three main types of volcanoes are as follows:
1. Composite volcanoes: These are also called as strato volcanoes. These are steep and formed by the layers of ashes and lava. The eruption from these volcanoes is in the form of pyroclastic flow. The pyroclastic flow is in the form of superheated mixture which consists of rock dust, ash, and hot steam. These volcanoes can rise above the 8000 feet. These are found in the destructive plate margins. Example of these volcanoes include the Mount Fuji in Japan.
2. Shield Volcanoes: These volcanoes are low and they have gentle sloping sides. These are formed by the layers of lava. Their eruption of lava is non-explosive. These produces the fast flowing fluids that can flow to many miles. These can destroy the nearby surrounding regions can cause injury and even death. These volcanoes are found in the region of constructive boundaries and also at the volcanic hotspots. The examples of shield volcanoes include the Maunaloa on Hawaii.
3. Dome volcanoes: These are also called as acid lava cones as these emit acid which is much thicker than that of the lava. These have steeper sides as compared to the shield volcanoes. The lava is thick and sticky as a result of this it cannot flow to far region and it cools and solidifies. The example of dome volcanoes include the Puy de Dome of Auvergne, France.
