The theory of Plate Tectonics can explain the global distribution of continents and ocean basins (first-order landforms), mountain ranges (second-order landforms), and individual volcanoes (third-order landforms. Volcanoes are produced by molten rock (magma) rising from the mantle through the Earth’s crust, flowing or exploding from vents in the crust and solidifying. Many volcanoes are subsequently eroded by running water and glacial ice.Required:Use the names of continents, oceans, or countries, and modifiers such as "eastern coast of...," or "northern boundary of," etc., to describe six general regions (e.g. "eastern coast of North and South America": obviously, this is merely an example, and is not correct).
