The Ring of Fire is the result of tectonic plates, huge slabs of Earth's crust that fit together like pieces of a puzzle. The plates are constantly moving atop a layer of solid and molten rock called
the mantle. Sometimes these plates collide, move apart or slide next to each other.

(A) It helps the reader to imagine how large and heavy they are.
(B) It helps the reader to consider their exact shapes and curves.
(C) It helps the reader to visualize how their edges meet and align.
