For dew formation, the surface temperature should reach near what?

Answer and explanation

Correct answer: Dew point

Correct answer: A, the dew point. Dew forms when a surface, such as grass, leaves, or a roof, loses heat and cools to the temperature at which the nearby air becomes saturated with water vapour. At this point, some vapour changes into tiny liquid water droplets on the surface. This process is condensation. The boiling point is related to rapid vaporisation, not dew formation. Sea level is a height reference and does not describe the temperature needed for dew. An earthquake focus is the underground origin of an earthquake and has no connection with atmospheric moisture. Remember: dew point plus a cool surface produces dew; if the temperature falls below freezing, frost may form instead.
