About Geomorphology: Earth's Interior, Rocks & Landforms

This quiz starts right at the centre of the Earth itself, working outward through the core, mantle, and crust, the several key discontinuities that separate them, and the seismic and other evidence scientists actually use to study a layer no one has ever directly seen.

It then covers the two great theories that explain why continents and oceans sit where they do, Alfred Wegener's continental drift and the modern theory of plate tectonics, along with the volcanoes and earthquakes that these same moving plates actually produce.

A large part of this quiz is then devoted to rocks themselves: the three major rock families, igneous, sedimentary, and metamorphic, how each one actually forms, and the continuous rock cycle that turns one into another over geological time.

It closes with the considerable forces of weathering, mass wasting, and folding and faulting that break rock down and reshape it, and the many distinctive landforms, river valleys, glacial troughs, desert dunes, karst caves, and coastal cliffs, that erosion and deposition actually carve across the surface of the Earth.
