Answering the question, according to the theory of plate tectonics, <u>the lithosphere is divided into plates</u>. This implies the correct answer is B.
The lithosphere, the outer shell of the earth is composed of nine major different plates. These plates are named based on the landforms that are found on each of them. Also the crust and part of the upper mantle join together to form the lithosphere.
<h2>Further Explanation</h2>
All the important major plate include
- Australian
- North American
- Indo Australian
- South American
- African
- Indian
- Pacific
- Antarctic
- Eurasian
Out of all the major plates, the Pacific plate is the largest and has 39,768,522 square miles and also equivalent to 103,000,000 square kilometers. Most of this plate can be found below the ocean.
The evolution of the theory of plate tectonics is one of the recent major discoveries by scientists.
According to the theory, the earth’s crust or the outer layer is made up of a series of plates consisting of lithospheric material that floats over the denser asthenosphere on the upper mantle across the Earth’s interior.
In other words, the outer layer, or the earth’s crust along with the upper mantle is splits into different sections and that the Earth is composed of plates.
