Volcano Flashcards
What is volcanism?
Process by which the maximise from the interior of that surface is known as volcanism
The inner temperature of the volcano is
6000°C
What is magma?
Magma is the molten form of rocks
What is lava?
When the magma is on the edge surface, that is above the crust layer
What is asthenosphere?
The weaker zone of the mantle is known as asthenosphere
What is crater?
The upper part of the volcano where the eruption happens and denunciations found
What is crater?
The upper part of the volcano where the eruption happens and denunciations found
Lonar Lake of Maharashtra is an example of
Crater lake
What is the largest crater lake in the world?
Lake Toba
What is divergent plate boundaries?
To tectonic plates, move apart from each other, so their least of premise leads to the melting of the magma, causing volcanism oceanic crust
What is convergent plate boundaries?
Continental and oceanic slide towards each other to form a subduction zone, so the oceanic plate submerged under the continental plate, forming a deep oceanic range of subducting plate, lowers the melting temperature of the whole mantle and creating magma
What is central volcanic types?
The lava comes out of the narrow pipe that causing an explosion during the action of the magma and the surface, thus forming mountains and islands
What is fissure volcano
In the lava comes from the surface and spread smoothly to a larger area, so they form landscape such as plateaus
The cooling of the lava firms
Igneous rocks.
In the lava cools externally, it is known as exclusive topography when the magma cools internally, then it is called intrusive topography .
What is discordant, intrusivetopography?
When the magma solidifies and disturbed the wrong structure, then it is called discordant intrusive topography
