Question

The theory of plate tectonics helps scientists explain

A. how ocean currents move over Earth’s surface.
B. why hurricanes occur.
C. how earthquakes and volcanic eruptions occur.
D. why Earth’s mantle is more dense than its crust

Answer 1

C. how earthquakes and volcanic eruptions occur.

Step-by-step explanation:

• The plate tectonic theory of the origin of the continent of the earth states that the activities of the tectonic plates ion different phases and cycle lead to the development of the various zone of the volcano and the thereby lead to the earthquakes and the other forme that was created over the earth surface.

• Thus the formation of the earthquakes and the volcanic and the island arc and the festoons on the water is an example of the transformation of the earth oceanic crust more than once and thus due to this alignment of rocks on the seabeds got their properties due to the movement of the plates to form beneath.

Answer 2

The correct option is C.
Plate tectonic theory explains the structure of the earth's crust and the many phenomena that are associated with it. This theory enables the scientists to know that there are movements in the interior of the earth which are responsible for volcanic eruptions and earthquakes.
