Hint: We are asked what the plates that makeup the crust of the earth are known as. First understand the meaning of earth crust. Recall the name used for plates present in the earth crust. Then check each option and select the correct option.

Complete answer:
The word planet means ‘wanderer’. This is because the planets do appear to wander listlessly across the night sky. The stars also move across the sky east to west but relative to each other, they appear fixed. The planets, on the other hand, seem to move relative to the fixed stars in backward and forwards directions. This is why they were called Wanderers.

We are asked what the plates that makeup the crust of the earth are known as.First let us understand what is the crust of the earth. The earth crust is the outermost layer of the earth.And the blocks that makeup the crust of the earth are called tectonic plates.

Hence, the correct answer is option C.

Note:There are major, minor and micro tectonic plates. There are seven major tectonic plates which are African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The world’s largest tectonic plate is the Pacific Plate and the smallest tectonic plate is the Juan de Fuca Plate which is now disappearing.
