Answer 2

Had there been no volcanoes, no new landforms would have been formed.

All of the land in the Hawaiian Islands was created due to volcanic eruption.

Volcanic material mixed in with the soil provides a lot of important nutrients.It gives us really fertile soils, which are great for farming and crops.

Volcanoes also provide a good environment for the formation of new habitats for animals, plants and insects.

Hot springs and geothermal energy are additional benefits.

Sulfur, copper and gold are produced from volcanic activity. Diamonds are also brought up to the surface from the mantle from a rare kind of magma, called kimberlite.

Volcanoes also provide a lot of building materials. Volcanic material can be made into blocks, and lot of the materials are mined, especially in places like Indonesia, where it’s used for conglomerate building blocks.

The volcanic material can be ground down to help make cement.
