Question

Which option tells the forces that influence the movement of earth's plates?

1) convection and gravity
2) fluids and temperature
3) gravity and solar heat
4) magnetism and convection

Answer 1

The movement of Earth's tectonic plates is influenced by convection in the mantle and gravity. These forces are central to the theory of plate tectonics which explains various geological features and movements of the Earth's crust.

Step-by-step explanation:

The forces that influence the movement of Earth's plates are convection in the mantle and gravity. This process is central to the theory of plate tectonics, which explains how the slow motions within the Earth's mantle move large segments of the crust.

These movements can cause the continents to gradually "drift" and lead to the formation of mountains and other geological features.

The power to move tectonic plates comes primarily from the slow convection of the mantle, a process that involves the upward flow of warmer material and the sinking of cooler material.

This occurs because heat escapes from the Earth's interior through convection, which also serves as a cooling system for the planet. So, the correct options that tell the forces influencing the movement of Earth's plates are convection and gravity.
