@thesciencestandards: Volcanic Eruption The absolute coolest thing about volcanos is magma buoyancy. The magma is less dense (you already know what that means) than the rock surrounding it. Magma "climb" up a conduit due to a free Bouyant thrust. So many wonderful lessons from this beautiful graphic representation of a volcano. #ngss4ESS32 #ngssmsess32 #ngssmsess32 #ngsshsls26 The elementary school standard revolves around solutions to reduce the impacts of natural Earth processes. Pretty cool stuff!
