Ok serious question this time,
The movement of tectonic plates is inferred by many scientists to be driven by
A) solidification in the lithosphere
B) density differences in the troposphere
C) convection currents in the asthenosphere
D) tidal motions in the hydrosphere

Answers

Answer:

c

Explanation:

layers of the earths crust

The movement of tectonic plates is inferred by many scientists to be driven by convection currents in the asthenosphere. Option (c) is correct.

What do you mean by Asthenosphere?

The asthenosphere is a solid portion of the upper mantle that is so heated that it can flow and behave like plastic. The asthenosphere supports the lithosphere. The asthenosphere can flow like toothpaste despite being solid. The topmost concentric layers of our globe are the asthenosphere and lithosphere.

Convection currents are created by the intense heat and pressure that exists within the earth. The tectonic plates that make up the earth's crust move as a result of these currents.

Therefore, Option (c) is correct. The movement of tectonic plates is inferred by many scientists to be driven by convection currents in the asthenosphere.
