The nature of a volcanic eruption is determined largely by the of the magma.

Chemistry

Explanation:

The composition of magma, the temperature of magma and the amount of dissolved gasses in the magma are all responsible for the nature of eruption.

Magma could be composed of dust, blocks, bombs, cinders and other gases.

The nature of eruption also depends on the temperature as magma could erupt at varying temperatures from 700C to 1300C and even at higher temperatures reaching 1600C.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
