The final exam will cover all lecture and lab topics from the semester. In lecture, we will focus on the concept of volcanism, and on hot-spots in particular. A mountain built from erupted material is also called a volcano. Relatively quiet, though lava can fountain at the vent. May get rivers and pools of lava.
Volcano explodes and emits huge cloud of ash.
Typically, a crater at the top. A crater is a small depression formed because eruptive material builds up around it. The lava armors the volcano so it doesn't erode away. Typically, a crater at the top. A large circular depression formed after explosive eruption.
