plate tectonics
plate tectonics is a theory that explains how significant land - forms are created due to earths subterranean movements. the theory of plate tectonics explains many geological phenomena, including mountain building, volcanoes, and earthquakes.
in plate tectonics, earths outermost layer is broken into large rocky plates, which sit on top of a partially molten layer of rock. these plates move relative to each other at different rates, from one to six inches per year. this movement is responsible for many formations, such as the himalayan mountains in asia and the san andreas fault in california.
a german scientist named alfred wegener published an article in 1912 about continental drift. he suggested that 200 million years ago, a supercontinent, called pangaea, began to break into pieces. the parts that moved from each other are the fragments we see today as separate continents. to support his theory, wegener pointed to similar fossils found in brazil and west africa. additionally, south america and africa looked as if they could fit together like puzzle pieces.

Explanation:

For Question 1, the text focuses on how plate tectonics explains geological formations, so C is correct as it summarizes the overall purpose. For Question 2, the continents today are fragments of the super - continent Pangaea as stated by Wegener's theory. For Question 3, "phenomena" in this context means occurrences like mountain - building, volcanoes, and earthquakes.

Answer:

Question 1: C. to explain how plate tectonics caused several of Earth's geological formations
Question 2: C. the supercontinent Pangaea
Question 3: B. occurrences
