LAVA FLOW

Different liquids flow at different speeds. Think about water and chocolate sauce; even when we compare equal amounts, the water flows faster, and covers the surface more quickly. The same goes for different volcanic eruptions. The lava that flows from the volcano can be very runny or very thick. The thickness (or viscosity) and temperature of the lava released during an eruption both determine the shape of the volcano. In this activity we will investigate the thickness of different fluids and predict what shape volcano they would make.
