Question

13. What are two of the processes that move tectonic plates over the surface of the Earth?

Answer 1

1. The plates in the planet’s surface move because of intense heat in the Earth’s core, that causes molten rock in the mantle layer to move.

2. This one is simple: The gravity and the rotation of the planet causes the plates to shift and move. 

Answer 2

Answer choices are:

A. Slab pull and crust conversion

B. Plate movement and convection currents

C. Connection and convection

D. Ridge push and slab pull

Correct answer choice is:

D. Ridge push and slab pull

Explanation:

Ridge Push: The process that occurs when magma arises at a mid-ocean ridge and drives oceanic plates in two separate ways apart from the ridge.

Slab pull: The process that occurs if a thick oceanic plate settles underneath a more resilient plate with a subduction zone, drawing the excess of the plate that pursues following it.
