The landmasses,
floating slowly on gigantic tectonic
plates, have inexorably moved across
the surface of the globe, sometimes
crashing into each other and throwing
up huge mountain ranges like the
Himalayas, and at other times drifting
away to isolate whole regions from the
rest of the world. Volcanic eruptions,
earthquakes, ice, wind, rain and the
other forces of erosion have also
played a part in forming, distributing
and redistributing the rocks and
minerals and shaping the Earth.
