Volcano, everyone hate volcano. What is lava. Lava is made up of crystals , volcanic glass, and volcanic gases. As “magma” get closer to the surface and cools, it begins to crystallize minerals like olivine and from volcanic gases. When lava erupts it is made up of a slush of crystals, liquid. The liquid “freezes” to from volcanic glass. “Magma” is hot fluid or semifluid material below or within the earth’s crust from which lava and other igneous rock is formed on cooling. Why we have volcanoes. Volcanoes are just a natural way that the Earth have have of cooling off and releasing internal heat and pressure. Volcano erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks cause it to rise. How many volcanoes are in the world. There are probably millions of volcanoes that have been active during the whole lifespan of the Earth. Guring the past 10,000 years there are about 1,500 volcanoes

Graffiti
A lot of people do graffiti, mainly young people. They paint on the wall and under the bridges at night and in a quiet area, where there are no police and not a lot people because it’s an unsafe area. Some people like graffiti and some people don’t like it. I think all graffiti is bad because it is ugly and a mess. Some walls have swear words on them. People do graffiti because their families don’t have time to sent the children to school and they don’t have work to do so. Some children paint on walls, it’s very good. I think they can be a painter or artist. They can get a job to spray paint for people who like graffiti. Good graffiti Bad graffiti
