Volcanoes And Earthquakes Questions
A volcanic dome is a mound or steep-sided mass of hardened lava that accumulates around the vent of a volcano. It is formed when highly viscous lava erupts and piles up near the vent, rather than flowing away like more fluid lava. Volcanic domes are often associated with explosive eruptions and can be composed of various types of lava, such as dacite or rhyolite.
