Quizplus · Accepted Answer

Shield volcanoes have the most gently sloping sides due to the low viscosity of the basaltic lavas that form them. Stratovolcanoes have steep sides due to the high viscosity of their lava, while cinder cones are typically smaller and have steeper sides due to the explosive eruptions that form them.
