Which of the following is not a correct statement of ideas from the theory of plate tectonics?A. Earth’s crust is broken into plates. B. Most earthquakes occurr at plate boundaries. C. Plates are destroyed at subduction zones. D. All volcanic activity occurs at subduction zones. E. Plates are created at mid-­-ocean ridges.

D. All volcanic activity occurs at subduction zones

Explanation:

Earth’s crust is broken into plates.

The theory of plate tectonic states that earth crust are broken or separated into tectonic plates. These plates are constantly moving relative to one another.  The plates collides, diverge or even move past each other as they move.  This theory is true.

Most earthquakes occurr at plate boundaries.

Most earthquakes occur at plate boundaries where plate collides, diverge or move past each other. Ring of fire is a known place where plates collides leading to subduction. This area is known for volcanism and earth quake occurrence. This statement is true.

Plates are destroyed at subduction zones

Plates are destroyed at subduction zones. Subduction zones are area where plate converge. These plates collides leading to the subduction of the less buoyant plate. Subduction usually occur when their is a collision between an oceanic crust and a continental crust. The oceanic crust is usually subducted after the collision. The subducted plate sinks into the aesthenosphere and are destroyed in the process. It is true plates are destroyed at subduction zone.

All volcanic activity occurs at subduction

Volcanic activity does not only occur in subduction zones . But it can also occur in hot Spot and mid oceanic ridges where plates diverge.

Plates are created at mid-­-ocean ridges.

Plates are created at the mid oceanic ridges. when plates diverge, at the mid oceanic ridge aesthenospheric material like magma are introduce to the surface. The magma solidifies to form new crust. The statement is true.
