Question

Which best states the theory of plate tectonics?

A. Earth's surface is made of different sections of rock that move apart and collide.

B. Earth's continents were once joined together as one land mass.

C. Earth's layer consists of the crust, the mantle, the outer core, and inner core.

D. Earth's most active volcanoes and earthquakes occur in the ring of fire.

Answer 1

"A" Would be the best answer. Although "C" is technically correct. the theory of plate tectonics is based on the fact that rock sitting on the mantle is shifted around, pulled apart, and consumed back into the mantle.
