QUES: Sunlight may be stored as gravitational potential energy after it strikes the Earth, as (for example) water evaporates from oceans and is deposited upon mountains (where, after being released at a hydroelectric dam, it can be used to drive turbines or generators to produce electricity). Sunlight also drives many weather phenomena, save those generated by volcanic events. An example of a solar-mediated weather event is a hurricane, which occurs when large unstable areas of warm ocean, heated over months, give up some of their thermal energy suddenly to power a few days of violent air movement.

This drives many weather phenomena, save those generated by volcanic events.
What is the answer?
ANS: Sunlight
QUES: Central, Western, and Balearic differ in the lexical incidence of stressed /e/ and /ɛ/. Usually, words with /ɛ/ in Central Catalan correspond to /ə/ in Balearic and /e/ in Western Catalan.
