This document discusses plate tectonics and describes the distribution of active volcanoes, earthquake epicenters, and major mountain belts. It explains that places where most earthquakes and volcanic activity occur mark the boundaries between lithospheric plates. As the plates slowly move relative to each other along these boundaries, geologic events like earthquakes, volcanoes, and mountain formation take place. The objectives are to describe this distribution and determine the scientific basis for dividing the lithospheric plates.

1. Let’s Mark the Boundaries

28. Plate
Boundaries

29. Remember:
 Places on earth where most of the
earthquakes originated or some
mountains and volcanoes were
formed mark the boundaries of each
lithospheric plate.
 Each plate is slowly moving relative to
each other, causing geologic events
to happen along their boundaries.

30. Remember:
 Plates are large pieces of the upper
few hundred kilometers of Earth that
move as a single unit as it floats
above the mantle.
 As plates interact along their margins,
important geological processes take
place,
such as the formation of mountain
belts, earthquakes, and volcanoes.
