Yes. The theory of plate tectonics is very broad, and it covers seafloor spreading, continental drift, plate boundaries and so on.
Uranus doesn't have any active plate tectonics. Uranus is made out of gas and does not contain any solid surfaces.
yes
Oceanic and continental.
yes
Continental crust and continental crust are made of different types of rock. The rocks in the continental crust do not contain as many of the heavier elements as the ones in the oceanic crust do.
The Oceanic plate denser than the continental plat because it contain magnesium,which is denser than aluminum found in continental plates.
The presence of magnetic domains of alternating orientation parallel to the plate boundaries.
No continental lithosphere contains more felsic rocks than oceanic lithosphere.
gas and petroleum
none they all contain some oceanic crust
because they can grow on the ocean floor and most life is concentrated near the continental shores. Hoped i helped :)
yes. very high amount of water vapor.
