- Plate Boundaries: The questions revolve around plate tectonics, focusing on the different types of plate boundaries and their associated features.- Convergent vs. Divergent: Convergent boundaries occur when plates collide, leading to mountains, volcanoes, and earthquakes. Divergent boundaries occur when plates move apart, forming rift valleys and oceanic ridges.- Subduction: Subduction is a process where a denser plate slides beneath a less dense plate, leading to volcanic activity.- Fault: A fault is a fracture in the Earth's crust where rocks have moved past each other.- Volcanic Island Arcs: Volcanic island arcs are chains of volcanoes that form along convergent plate boundaries, often parallel to trenches.- Mantle Plume: A mantle plume is a column of hot rock that rises from the Earth's mantle, creating volcanic activity.- Earthquakes: Earthquakes are caused by the sudden release of energy when rocks along a fault break.
