Plate tectonics describes the movement of very large chunks of land underneath the ground. The continents have moved around due to the plates below us moving, which is caused by the internal flow of gasses and molten metal underneath us.

‘Climate’ is an old idea, but an idea which retains tremendous power, versatility and utility in today’s world. For the Ancient Greeks, climate worked both as index and as agency , and this dual function has recurred throughout human cultural history and it works too in contemporary discourses about climate change. Climates change physically, but climates can also change ideologically. What climate means to different people in different places in different eras is not stable. If culture is concerned with how human meaning, symbolism and practice take on substantive and material forms, then studying climate through culture is likely to be a fruitful activity.
Answer:
This question is actually an English Language question not a Geography question.
The task is to select the option that is most grammatically correct with respect to Subject-Verb agreement and parallelism.
Subject verb agreement simply means the subject and verb must agree in number. This means both need to be singular or both need to be plural.
The Answer therefore is A) <em>core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies of the flow of heat from the inner through the outer planet and of the formation and periodic reversal in direction of Earth's magnetic field</em>
Explanation:
In the line <em>"The discovery is responsible for advancing the studies (1. of the flow of heat 2. of the formation and periodic reversal)"</em>
The first clue is that the subject is the discovery, a singular and therefore the main verb will be "is". So eliminate options C and D.
Option B misses the parallel "of" in the second part.
Option E distorts the parallelism by stating "of how" in the second part
Only option A only maintains the prepositional parallelism
Dusted!
