What does the crustal plates movement causes?
Earthquakes. Pressure in the Earth's core.
How do crustal plates interact with earthquakes?
sometimes they slide around and that movement creates earthquakes
What is the cause of the Italian earthquake 2009?
All earthquakes have the same cause, which is the movement of the Earth's crustal plates resulting from convection currents in the magma upon which they float.
What are the two theories on the continental divide?
The main theory on the continental divide is that they relate to the plate techonics theory of the Earth's crust. The other theory is the continental drift theory where lighter rocks float on heavier crustal material.
When the ocean floor collides with a crustal plate what happens?
it subducts underneath the crustal plate
When is the last movement of the crustal plate?
The crustal plates are in constant motion, there is no last movement
What is the relationship between earthquakes and crustal movement?
Crustal movements cause earthquakes because of the sound waves and the movement underground.
Why movement of crustal plates depend on heat?
The heat in the Earth's core makes the magma more liquid and allows the movement of the crustal plates.
What are the movement of crustal plates?
due to textonic movement of earth and valconic erosion
What is deformation that doesn't involve crustal movement?
epeirogeny
What is the behavior of the crustal plates in relation to the asthenosphere?
Crustal (or lithospheric) plates are pulled or pushed by the movement of heated rock in the asthenosphere.
Where does crustal place movement occur?
hi their people of this earth
What is primary causes of crustal movement?
Convection currents in the mantle.
What may happen due to movement of crustal plates?
earthquakes
What is crustal movement that doesn't involve deformation called?
epeirogeny
What may happen due to the movement of crustal plates?
earthquakes
The best evidence of crustal movement is?
marine fossils found on a mountaintop (: this is what i have
