Q: Which of the following is the outer layer of the Earth that is made of plates which fit together like a jigsaw puzzle ?
  • A. Mesosphere
  • B. Biosphere
  • C. Lithosphere
  • D. Asthenosphere
Correct Answer: Option C - The lithosphere is the outer solid portion of Earth that includes the crust and the uppermost part of the mantle. The theory of plate tectonics proposes that the lithosphere is divided into a series of plates that fit together like the pieces of a jigsaw puzzle. These plates are mobile, moving in constant, slow motion measured in rates of centimeters per year. The movements of plates over millions of years resulted in the opening and closure of oceans and the formation and disassembly of continents. it is significant that, most earthquakes are caused by large-scale movements of the Earth's lithospheric plates and occur at the boundaries between the plates.
