Here are just some of the things we get from them. Because some lava from many years ago has broken down, it makes the soil very rich is some places such as Indonesia, India and Italy. From areas in Montana, USA and Chile. Sometimes in places like New Zealand, the gases and magma don't always erupt. Lot's of things we use at home are made from crushed stone from the volcano, such as toothpaste, cleanser, make up and other things.
Roadways also contain material from the crushed stone.
When I returned, I visited with my friend from the third grade to talk about volcanos and wanted to share with you what my friend had to say about them. They can burn anything in their path. If you pour a lot of water on the lava, it will turn to stone. If you get close to volcanos, you have to be careful if they are going to erupt. Volcanos are mountains with lava inside and they have a big hole in the middle at the top.
