What type of volcano produces Rhyolite?
Regional SpecificsRhyolite usually forms in continental or continent-margin volcanic eruptions where granitic magma reaches the surface. Rhyolite is rarely produced at oceanic eruptions. What is a rhyolitic volcano? Rhyolite caldera complexes are the most explosive of Earth’s volcanoes but often don’t even look like volcanoes.

What type of rock reacts with acid? carbonate rocks Some sedimentary rocks are bound together with calcite or dolomite cement. Sandstone, siltstone, and conglomerate sometimes have
How does a lava lamp relate to plate tectonics?
Regional SpecificsHeat within the asthenosphere creates convection currents (similar to the currents that can be seen in the lava lamp). 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?
Regional SpecificsLava 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
