The answer is plate tectonics theory.

The idea that earth’s lithosphere is divided into large, moving sections is called the Plate Tectonics Theory.

The Plate Tectonics Theory is not attributed to any single person or geologist. In fact, it developed over a number of years due to scientific exploration and the research of the Earth's crust.

The theory explains how the Earth is divided into large sections of plates, that are always moving, leadint to changing shape of the landmass on Earth. The movement of these plates is what casues earthquakes.

It is based on the theory of continental drift and was widely accepted in the scientific community by the 1950s.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
