Question

what is the process of volcanic eruption​

Answer 1

$\huge{\bf{\red{\underline{\underline{Answer}}}}}$

This molten rock is called magma when it is beneath the surface and lava when it erupts or flows from a volcano. Along with lava, volcanoes also release gases, ash, and rock. It's a super hot mix that can be both incredibly destructive and creative. Volcanoes form at the edges of Earth's tectonic plates.

Before a volcano erupts, there is normally an increase in earthquakes and tremors near and under the volcano. These are caused by magma (molten rock) pushing upward through the rock under the volcano. The ground may crack open and allow steam to escape.

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. ... If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises.

Answer 2

Answer:

When a volcano releases magma, it causes a volcanic explosion. Volcanic eruptions can be violent or fairly quiet and expansive. Lava flows are created by effusive eruptions, whereas ash and pyroclastic density currents are created by explosive eruptions.

Explanation:

what is the process of volcanic eruption​:

When it rises to the surface from below, this molten rock is known as magma, and when it pours out of a volcano, it is known as lava. Volcanoes also spew forth gases, ash, and rock in addition to lava. This explosive mixture has the power to be both tremendously destructive and constructive. The margins of the tectonic plates on Earth are where volcanoes occur.

The frequency of earthquakes and tremors in the area around and under a volcano often increases before it erupts. These are brought on by magma (molten rock) pushing through the volcano's base rock and rising to the surface. Steam might escape from the earth if it splits apart.

When magma, or molten rock, rises to the surface, volcanoes erupt. When the earth's mantle melts, magma is created. Where tectonic plates are separating or being driven beneath one another, melting may occur. Gas bubbles cannot easily escape from thick magma, which results in pressure building as the magma rises.
