Geophysicists use seismic defraction and reflection techniques to identify changes in the composition and density of the earth's interior.
The base of the crust is marked by a region of significant change in the velocity of seismic waves. This region is known as the Moho (Mohorovičić discontinuity) and is cuased by the change in compostion of the materials forming the interior of the earth.
Geophysiciscst can measure the travel time of seismic waves through the earth and can use this to estimate the depth of this region and hence the thickness of the crust in different areas.

What are the large thin plates that move relative to one another on the outer surface of earth called?
They are called tectonic or lithospheric plates.
The lithosphere is broken up into sections called?
Tectonic plates
What is the difference between Continental plates and Tectonic plates?
Continental plates are tectonic plates. They are tectonic plates upon which continents rest, and they move as do all tectonic plates. Basically, there is no difference, other than the fact that oceanic plates are another type of tectonic plate.
What is the difference between a tectonic hazard and a tectonic event?
a tectonic hazard is a disaster caused by the moving of tectonic plates.....anda tectonic activity is the moving of tectonic plates........
What causes friction on tectonic plates?
the movement of tectonic plates
Why is the thickness of the tectonic plates not the same all over?
because the thickness of the crust is different

They are called tectonic or lithospheric plates.
What are the plates that make up Earth's crust?
Tectonic plates
The lithosphere is broken up into sections called?
Tectonic plates
I am part of lithosphere but you move around on top of the asthenosphere?
The answer is Tectonic Plates

What causes friction on tectonic plates?
the movement of tectonic plates
Earthquakes occur mainly allong the edges of?
Tectonic plates and fault lines created by the movement of tectonic plates.
What can tectonic plates also be called instead of tectonic plates?
Tectonic plates are also "Continental Crust" and "Oceanic Crust". Also lithospheric plates.
Can tectonic plates known as crustle plates?
Yes, tectonic plates are also known as crustal plates.
Who named the tectonic plates tectonic and why?
harry hess named the tectonic plates but I'm not sure why =/
