Sequence the following sentences in a coherent passage.
: This fortuitous geological event generated a colossal amount of energy and heat that resulted in the rocks rising to an average height of across the contact zone.
: Thus, the geophysicists tend to think of the Himalayas as an active geological event rather than as a static geological feature.
: The natural process of the cooling of this massive edifice absorbed large quantities of atmospheric carbon dioxide, altering the earth's atmosphere and making it better suited for life.
: Many millennia ago, a breakaway chunk of bedrock from the Antarctic Plate collided with the massive Eurasian Plate.

Answer: C
To find the correct sequence, we can analyze the logical connections and referents between the sentences:
- Opening Sentence (S): Sentence S introduces the primary historical event—the collision of a breakaway chunk of bedrock from the Antarctic Plate with the Eurasian Plate. This serves as the natural starting point of the passage.
- Connection between S and P: Sentence P begins with "This fortuitous geological event...", which directly refers back to the collision described in S. Therefore, P must immediately follow S (S P).
- Connection between P and R: Sentence P mentions that the rocks rose to an average height of . Sentence R then refers to "this massive edifice" (the newly formed mountain range) and its cooling process. Thus, R follows P (P R).
- Concluding Sentence (Q): Sentence Q starts with the transition word "Thus", drawing a conclusion about the Himalayas being an active geological event based on the processes described. This naturally concludes the passage.
Combining these links, we get the coherent sequence: S P R Q (SPRQ).
