What natural events can occur when crustal plates move over each other?
earthquakes and tsunamis
How have crustal plates moved over time?
Molten magma from the mantle rises at the top oceanic ridge, cools and solidifies, continually forming a crustal plate. Hundreds to thousands of miles from the ridge the plate moves downward into the mantle at the contact with another plate and melts. The continuous process resembling a large "conveyor belt" moves the crustal plate a few centimeters each year.
What is the boundary between plates where relative motion can cause a quake called?
the large sections of the earth's crust that move relative to each other
Is the earth getting larger and wider when plates drift away from each other?
No, the relative sizes of the oceans change.
How is crustal rock heated inside the mantle?
Crustal rock is heated inside the mantle during divergent boundaries where new crust is generated as the plates pull away from each other. In mid-ocean, this movement results in seafloor spreading and the formation of ocean ridges; on continents, crustal spreading can form rift valleys.
Major mountain ranges are formed when crustal plates are what?
push into each other
What is formed when crustal plates move toward each other?
when tectonic plates move toward each othe forms
What natural events can occur when crustal plates move over each other?
earthquakes and tsunamis
Forms when two crustal lithospheric plates slide past each other?
Sliding Boundaries
What happens to the Earth's crust when a strike slip fault happens?
Crustal plates are grinding past each other in a strike-slip fault.

What happens when crustal plates slide past each other?
Earthquakes occur and faults are created. (Next: transform boundary) no crust is created or destroyed.
What is the boundary between plates where relative motion can cause a quake called?
the large sections of the earth's crust that move relative to each other
What are the crust and lithosphere?
It consist of large sections called tectonic plates, which move relative to each other.
Is the earth getting larger and wider when plates drift away from each other?
No, the relative sizes of the oceans change.

Are the pacific plates and the antarctic plates moving towards each other or away from each other or past each other?
the plates are moving away from each other.
