what we call the point of eruption
Answers
The event when necessary conditions are fulfilled inside the volcano and it is ready to start eruption is called the point of eruption.
There are multiple of reason to cause eruption which are complex, diverse and caused due to multiple.
Inside the Earth’s surface and crust layers of molten rock exists.
Because of the high temperatures at the core, and molten rock form magma.
Magma comprise of various gases – mainly carbon dioxide, steam and sulphur dioxide.
It is capitulated in magma chambers which are sealed under a lid of solid rock.Due to its liquid state, the magma is less dense than the rock above it and begins to increase in volume.
It along with water vapor escapes as bubbles, increasing the density of the carbon dioxide and sulfur dioxide.
Within a short time these gases expand to 1000 times their original volume, increasing the pressure inside the chamber to such an extent that it reaches the point of eruption.
When necessary conditions are fulfilled inside the volcano, the volcano is ready to start erupting is called the point of eruption.
EXPALANATION:
Volcanic eruption take place, burning materials from the interior of the Earth's interior are hurled out of the volcano. Rocks, lava, gas and dust compounds are a few of ejecta. Eruptions come from the top of the volcano or its side branches.
When there is an earthquake, little vents are formed where magma is permitted to form. Magma is thrust up by way of these vents and towards the crust of the volcano.
Steam vents are formed when the magma touches a particular level and touches a boiling point that begins the eruption. The eruption may lead to total eruption. This is when gas propelled explosion transmit magma to the crust of the volcano creating lava inundating from the volcano.
