These convection currents cause the tectonic plates to move several centimeters per year relative to each other. How does a lava lamp relate to mantle convection and plate tectonics? The Earth’s mantle has convection currents because

How do lava rocks work in a fire pit?

Lava rocks work well in a fire pit because they disperse the flames, spreading the heat and giving the pit an appealing look. Heat coming from the burner goes straight upwards, but if you add a layer of lava rocks to the fire pit, the heat will spread out around the burner. How do you
