Is the moving portion of earth's crust and upper mantle called a ridge?

Not quite. These are known as tectonic plates. A (mid ocean) ridge is a type of boundary between differing tectonic plates which are diverging or moving away from each other..

What states that the earths lithoshere is broken into huge moving slabs of rock driven by motions in the mantle?
The theory of plate tectonics states that the lithosphere is broken into moving pieces of earth driven by convection currents located inside the mantle.
When land masses on earths crust are moving what is it called?
earthquake
Are most volcanoes on land caused by the earths plates moving away from each other or moving toward each other?
all volcanoes are caused by the earths plates moving toward each other and that is called convergent boundaries.
What are moving pieces under the earths surface that form the earths crust?
The answer is tectonic plates floating on the lithosphere. Does that answer your question? LOL :)
What is a number of rigid but moving pieces of earths surface?
Lithospheric plates are a number of rigid but moving pieces of earths surface.
What is the moving portion of earths crust and upper mantle?
a moving portion of earths crust and upper mantle is called a ridge that's when the ocean floor has underwater volcano that erupts
What are oceans current are formed by what?
Moving plates in the earths mantle.
How does the earths crust move?
It gets a free ride on the moving surface of a mantle convection current.
What would happen to the earths plates if the mantle completely cooled down?
They'd stop moving.
Why is the earths crust always moving?
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.
What states that the earths lithoshere is broken into huge moving slabs of rock driven by motions in the mantle?
The theory of plate tectonics states that the lithosphere is broken into moving pieces of earth driven by convection currents located inside the mantle.
What process causes earths plates to move?
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
Which process is currently accepted explanation of the movement of drifting continents?
the convection currents in the mantle under the earths curst is moving the broken plates in earths lithosphere causing the plates slide across the lithosphere. this process is called tectonics. (jon lay wrote this,)
The activity of the earths moving plates is called?
tectonics
When land masses on earths crust are moving what is it called?
earthquake
Earths lithosphere is broken into huge moving slabs of rock driven by motions in the mantle?
The motion in the mantle is known as convection currents which helps move earth's slabs, known as plates. Convection occurs in the upper mantle known as the asthenosphere.
What is the activity of the earths moving plate called?
ok i can help u with this, the moving of the techtonic plates is called faulting or fault :]
