these volcanoes have quiet eruptions and have huge gently sloping sides.
What is a shield volcano
100
this type of plate boundary forms a volcanic arc
What is convergent plate
200
this fast moving body of hot gases and solids tend to follow valleys
What is pyroclastic flow
200
this low viscosity magma is thin runny and erupts non explosively it flows freely and has a high heat
What is basaltic
