1. Volcanoes can be helpful because 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.
Volcanoes are harmful because:
They release poisonous sulphuric gases into the air, which also cause acid rain.
They make lava, which can be extremely hot, which kills plants and animals, including humans.
They throw out dust and ash, which can block out sunlight, for the surrounding area.
They can cause an incredibly hot cloud, which races down the steep slope, at 100s of mph, and burns everything in its path.
Volcanoes are harmful because: * They release poisonous sulphuric gases into the air, which also cause acid rain. * They make lava, that can be 1000s of degrees Celsius (extremely hot!), which kills plants and animals, including us. * They throw out dust and ash, which can block out sunlight, for the surrounding area. * They can cause an incredibly hot gas-cloud, which races down the steep slope, at 100s of mph, and burns everything in its path. Volcanoes are helpful because: * They are popular tourist attractions. * They stop the Earth from exploding. * They throw out tonnes of ash, which fertilises the soil, in the area, really well.
When valcanoes erupt they force out lava from the earths mantle we all know that but after the lava cools down it forms into igneious rock forming land. So valcanoes can create islands, thats how valcanoes are helpful.
They make the ground more fertile. They keep the temperature on earth regulated.
The only thing they do good is not erupt and cause deaths to people and other living things.
Volcanoes that form underwater or near Coastlines can contrubute to the formation of ne land. Volcanic ash helps vertilize soil, making it excellent for crops.
Volcanoes are harmful because of lava.
