When you think of a volcano, you probably think about how they can be very destructive. they are, after all, natural disasters. however, volcanoes can have constructive consequences. one example of volcanoes as a constructive process would be a volcano eruption a) spewing hot lava. b) forming an island. c) starting an avalanche. d) covering the land with ash.

B) Forming an island  

Explanation:

Volcano is an opening in the Earth's crust (surface layer of Earth) through which materials originating from the mantle are expelled to the surface. These materials, in general, appear in a liquid-paste and incandescent state are called magma. It is a material present in the layer immediately below the earth's crust - the mantle. However, from the crevice of the volcano, gaseous materials, dust and solid rock can also be emitted.

Volcanoes may appear at the bottom of the oceans. After successive eruptions and the consequent cooling and consolidation of the magma, this volcano can reach the surface and form an island or sets of islands. This is the case of the islands of Fernando de Noronha in Brazil and the archipelago of Hawaii in the Pacific Ocean. The islands formed by extrusion of magma are called volcanic islands.

The formation of islands is an example of the constructive consequences of volcanoes.
