In History we learned about the Mayans. They were a city-state society. We read six poems, a lot from Germany. The thickness of lava determines who much gas it can trap. Thick lava can trap more so the pressure builds up. It also moves slower down the volcano and makes the sides steep. Runny lava lets gas escape almost right away and volcanoes with runny lava frequently erupt in small amounts. It also runs down the volcano fast so the slopes are shallow.
