Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. evaporation.
Context: The sentence refers to the process where water from oceans, lakes, and rivers is heated by the sun and turns into water vapour.
Meaning of the words:
Evaporation – the process of liquid water turning into water vapour due to heat.
Condensation – the process of vapour turning back into liquid.
Sublimation – the process where a solid turns directly into gas, skipping the liquid state.
Liquefaction – the process of turning something into a liquid (often used in geology or refrigeration).
Correct word: Evaporation
Reason: The sun heats the water and turns it into vapour — this is called evaporation.
Final Sentence: At the heart of the water cycle is the process of evaporation. This is where water from oceans, lakes, and rivers is heated by the sun and turns into water vapour.
Hence the chosen option is correct.
