Question

What are the types of volcanic eruptions?

Answer 1

There are two predominant types of volcanic eruptions: Effusive eruptions – magma rises through the surface and flows out of the volcano as a viscous liquid called lava. Explosive eruptions – magma is torn apart as it rises and reaches the surface in pieces known as pyroclasts.

Answer 2

Volcanic Eruptions are of two types:- Central eruptions and fissure eruptions

Explanation:

• Volcanic eruptions are broadly classified into two type:-

1. Central eruptions
2. Fissure eruptions

• Central eruption- In central eruption,the emission of lava takes place through a vent.Such a volcano usually exhibits cone-and-crater arrangement. This volcano may have parasitic cones  on the flanks of main structure.
• Fisuure eruption-In this type of eruption,basic lava issue  relatively quietly from linear fissure in the earth's crust. These lavas cover a very large area before solidifying and considerable thickness of a rock is formed from repeated eruptions.
