3. WHAT IS A TECTONIC
PLATE?
 A tectonic plate (also called lithospheric plate) is a massive,
irregularly shaped slab of solid rock, generally composed of both
continental and oceanic lithosphere. Plate size can vary greatly,
from a few hundred to thousands of kilometers across; the
Pacific and Antarctic Plates are among the largest. Plate
thickness also varies greatly, ranging from less than 15 km for
young oceanic lithosphere to about 200 km or more for ancient
continental lithosphere (for example, the interior parts of North
and South America).

5. 
The Main Features Of Plate
Tectonics Are:
 The Earth's surface is covered by a series of crustal plates.
 The ocean floors are continually moving, spreading from the center,
sinking at the edges, and being regenerated.
 Convection currents beneath the plates move the crustal plates in
different directions
 The source of heat driving the convention currents is radioctivity
deep in the mantle
.

Creates Three Types of
Tectonic Boundaries:
 Convergent Boundaries
 Divergent Boundaries
 Transform Boundaries
