Answer:
The answer is Option B: plate tectonics.
Explanation:
Plate tectonics is a theory about the structure of the earth's crust. In plate tectonics, the continents are viewed as a part of a system of rigid lithospheric plates which move slowly over the underlying mantle of the Earth. The model for plate tectonics builds on the concept of continental drift, which is an idea developed during the first decades of the 20th century. In continental drift theory, all the world's continents were once joined into a land mass that geologists have called Pangea during the late Paleozoic and early Mesozoic eras. It began to break up about 175 million years ago. In the beginning in the late Triassic, the continents began to break up with Laurasia comprising with what is North America and Eurasia and Gondwanaland which was South America and Africa, India, Arabia, Antarctica, and Australia. The shift in plates and their movement create mountain ranges and continents form and move to different latitudes that change the climate as these land masses moved.

A substance that cannot be broken down into simpler substances by chemical or physical means is called <u>an element. </u>
Explanation:
An element is the ‘purest and simplest’ form of matter or a substance.
An element is considered pure because all of its atoms are of a similar kind with a unique set and same defined number of protons. The atoms of an element exhibit the same set of properties. They can neither be broken down further into simple components nor can be converted to another element. Similarly, elements also cannot be destroyed or created by a chemical reaction. There are around 118 elements like oxygen, hydrogen, carbon, gold, iron, copper, platinum etc.
