The major types of plate tectonic boundaries are:
Divergent Plate Boundary: The area where two plates are moving in relatively opposite directions and new crustal material is being created. Examples would be the mid-ocean ridges, and the East African Rift.
Convergent Plate Boundary: The area where two tectonic plates are moving toward each other and one of two things happens; either the more dense plate subjects under the lighter plate and heads toward the mantle, or, if the plates are of similar density, they cause uplift and mountain forming events. Examples would be the oceanic to continental crustal collision creating the Andes Mountains, and the continental to continental crustal collision creating the Himalayan Mountains.
Transform Plate Boundary: The area where two plates are grinding past each other, snapping into place from elastic rebound as they go, causing numerous earthquakes. The San Andreas Fault is an example of a transform plate boundary between the North American and Pacific plates.

What are in constant motion and change the forms of the earth crusts?
tectonic plates
Why is the earth's crust in constant motion?
Convection currents of heat underneath the earth's crust in the mantle (magma) cause the tectonic plates of the earth's crust to move.
What is the motion of earths plates?
Slow and constant.
What would happen if the continents were moving?
The continents are moving. The tectonic plates that make up the continents are always in constant, but miniscule, motion. Often this movement results in earth quakes along the tectonic fault lines due to collisions between them.
What concepts is part of the theory of plate tectonics?
the tectonic plate theory is....when the tectonic plates move together to make a theory

Are in constant motion and change the forms of the Earth's crust?
Tectonic Plates ----APEX ;D
Where do plates float?
The Earth's tectonic plates are in constant motion. This movement is possible because they lay on top of the asthenosphere which is the outer mantle.
The Earth's tectonic plates are in constant motion due to several factors Temperature and density differences in the plates cause push and pull forces that move the plates?
The volcanic activey under the crust causes the tectonic plates to move

mantle convection
How does the motion of the tectonic plates relate to continental drift?
Continental drift is the theory that "plates" on the Earth are constantly in motion and have been for millions of years. Tectonic plates are the actual moving plates.
