What happens if a plate tectonic broke?

Answer 1

Strength Activator Plate Movement

The movement of tectonic plates can occur because of the relative density of oceanic lithosphere and asthenosphere is relatively weak character. The release of heat from the mantle has been found, the original source of energy that drives plate tectonics. Approved view now, though still quite debatable, is that the excess density of oceanic lithosphere that makes infiltrate downward in subduction zones is the most powerful source of plate movement.

At the time of its formation in mid-ocean ridge, oceanic lithosphere initially have a lower density than the surrounding asthenosphere, but this density increases with aging due to cooling and thickening. The magnitude of the density of old lithosphere relative to the underlying asthenosphere allows the infiltration into the mantle at subduction zones so that the source of most of the driving forces-the movement of plates. Weakness of the asthenosphere allows the plates to move easily towards a subduction zone [19] Although subduction is believed to be the strongest force driving plate-movement, there is another driving force plate as evidenced by the North American plate, Eurasian plate is also moving but did not experience subduction anywhere. Driving source is still a topic of intensive research and discussion among scientists of Earth Sciences.

Two and three-dimensional imaging of the Earth's interior (seismic tomography) shows a heterogeneous density distribution throughout the mantle laterally.Variations in density may be material (from rock chemistry), mineral (from variations in mineral structure), or thermal (through thermal expansion and contraction from heat energy). Manifestation of the lateral density heterogeneity is mantle convection from buoyancy forces (buoyancy forces) [20] How mantle convection relates directly and not by movement of the planet is still a field that is being studied and dealt in geodinamika. With one way or another, this energy must be transferred to the lithosphere that the tectonic plates to move. There are two main types of styles that influence the movement of planets, ie friction and gravity.

Answer 2

an earthquake would not happen without plate tetonics

Answer 3

I think our continents would not be in their present-day locations and we would be living on the supercontinent Pangaea.

Answer 4

The earth would explode because there wold be no openings to release pressure.
