The theory that suggests continents are in constant motion is called the (a) theory. This theory was made by (b) but was not proven until long after his death. (c) , which is the process by which new oceanic crust forms along a (d) provided scientists with the "how" and "why" the continents moved.
Rising mantle material at mid ocean ridges creates the potential for plates to move away from the ridge is called what?
Ridge push
Slab pull
Convection currents
Gravity nudge
As a plate sinks, it pulls on the rest of the plate with this force?
Ridge push
Slab pull
Reversed polarity
Why do continents move?
Centrifugal force from the Earth's rotation
Continents pushing through the mantle
Seafloor spreading along mid-ocean ridge
Global warming from rising CO2 levels
Theory that states the Earth's surface is made of rigid slabs of rock/plates that move in respect to each other.
(a)
What is the force behind the plate tectonic theory
Convection currents
