Document Summary
Barrier islands: are coastal landforms and a type of dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. Basalt: is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Base level: of a river or stream is the lowest point to which it can flow, often referred to as the "mouth of the river" Body waves: is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth"s surface. Caldera / supervolcano: volcanic eruptions sometimes empty their stores of magma so swiftly that they cause the overlying land to collapse into the emptied magma chamber, forming a geographic depression.
