A column of air mass extend from surface to a height of 10 km moving eastward along 30 °N isobars a north-south oriented mountain range. While crossing the mountain range, the air mass acquires a relative vorticity of −3.65 × 10⁻⁵ s⁻¹ at the top. If the air mass maintains the same latitude and potential vorticity, the height of the mountain range is ______ km. (Round off to the nearest integer.) [Assume the angular velocity of the Earth is 7.3 × 10⁻⁵ s⁻¹ and initial relative vorticity is zero.]

Sequence the following sentences in a coherent passage.

P: This fortuitous geological event generated a colossal amount of energy and heat that resulted in the rocks rising to an average height of 4 km across the contact zone.

Q: Thus, the geophysicists tend to think of the Himalayas as an active geological event rather than as a static geological feature.

R: 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.

S: Many millennia ago, a breakaway chunk of bedrock from the Antarctic Plate collided with the massive Eurasian Plate.
