Volcanoes are helpful, because when a volcano erupts it spits out lava, after a while the lava dries out and hardens, sometimes the dried out lava forms a new island. Also, because some people live near volcanoes for heat. When it's very cold outside the lava heats the volcano also heating any residents that live around the volcano.

∙ 12y agoAs the cooled lava (usually called basalt) breaks down, it tends to form soil that is particularly rich in minerals and thus can be quite fertile. The soil is rich because the volcanic tephra released in eruptions is easily weathered by rain. This process breaks down nutrients in the ash and rock delivering it slowly to the plants.
Volcanoes also create brand new islands.
Another volcano benefit are the many precious gems and building materials that can only come from volcanoes. Opals and obsidian are produced in volcanoes. Hardened volcanic ash, called tuff makes a strong, lightweight building material. The ancient Romans used tuff to make a strong, lightweight concrete for walls, and buildings. The roof of the Pantheon in Rome is made of pumice concrete because it's so lightweight. Volcanic eruptions also produce pumice stones, which people have used to remove excess skin.

Why are studies of volcanoes helpful to scientists who wish to understand the greenhouse effect?
Volcanoes, like the burning of fossil fuels, are also a source of the primary greenhouse gas, carbon dioxide.
Are shield volcanoes and volcanoes the same?
Not necessarily. Shield volcanoes are volcanoes, but not all volcanoes are shield volcanoes.
What type of vocanoes are there?
composite volcanoes shield volcanoes cinder cone volcanoes spatter cone volcanoes complex volcanoes
What are three types of volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.
What 2 types of volcanoes are there?
There are three. From smallest to largest, they are: Cinder Cones, Composite Volcanoes (also called Strata Volcanoes), and then Shield Volcanoes.
Why is thermal imagery helpful when studying volcanoes?
Thermal imagery is helpful when researchers are studying volcanoes because it allows them to see the volcanic heat and identify new lava flows. Thermal imagery help analyze heat patterns of volcanoes.
Are volcanoes harmful?
Volcanoes can be usually considered harmful, but in some cases, volcanoes can actually be helpful, so this is a win-win situation. Or a lose-lose. Who knows.
What is the surface condition on Venus?
very mountainouse and has some volcanoes hope this was helpful
What are helpful thing volcanoes do?
They provide ash for crops which helps them grow and nourish.
How volcanic eruptions can be be helpful?
Vocanoes can be helpful because the earth's first oceans and atmosphere were formed from the gases given off by volcanoes. Volcanoes have also shaped the earth's landscape, many of our mountains, islands, and plains have been built by volcanic eruptions.

Are volcanoes helpful?
yes. Volcanoes can be helpful because: 1. The volcanic soils are the richest and you can earn a farmland. 2. It can bring diamonds from deep under the earth. 3. Lava and tuffs can be use for building. 4. Engineers use steam by rocks of the volcano to make electricity.
Are shield volcanoes and volcanoes the same?
Not necessarily. Shield volcanoes are volcanoes, but not all volcanoes are shield volcanoes.
What are three types volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.
What type of vocanoes are there?
composite volcanoes shield volcanoes cinder cone volcanoes spatter cone volcanoes complex volcanoes
What are the two type of volcanoes?
there are three and they are Active Volcanoes, Dormant Volcanoes, and Extinct Volcanoes.
Do volcanoes need lava to be known as actual volcanoes?
No, volcanoes do not need lava to be volcanoes.
