Volcanoes on the Earth's Crust
My name is Kim Allen and I'm a second grade teacher at Augusta Prepratory
Day School and this web page lesson helps teach my second graders about
A volcano erupts when molten rock and gases-called magma- flow through
a crack in Earth's crust. Volcanos mostly happen where the Earth's
moving plates open up cracks and weak spots in the crust. When a
volcano erupts, the gases escape into the air and lava pours out.
Around the volcanoes opening a cone is formed. These cones can turn
into mountains over time.
