what are a shield volcanoes features
broad with gently sloping banks erupts runny lava, produces quite eruptions, forms over hotspots
300
what is seafloor spreading
new lava makes the new crust and pushes the other crust away

whats the theory of plate tectonics
magma moves and that movement moves the continents

what are the lithosphere
the lithosphere is the top part of the mantle and more solid

what is categorized as catastrophic earthquake
Total destruction, objects are thrown into the air, rivers and topography altered

what are the districts of a composite volcano
large mountain with steeply sloping banks erupts thick lava ash and cinders. produces highly explosive eruptions, forms along convergent plate boundaries
