Description:

The correct answer is:

✅ Cooling of objects

Why?

Dew forms when:

Surfaces (like grass or cars) cool overnight by radiating heat into space.

Moist air contacts these cold surfaces, causing water vapor to condense into liquid droplets.

Key Conditions:

Clear skies: Maximizes radiative cooling.

High humidity: More water vapor available to condense.

Calm winds: Prevents mixing of warm air.

Why Not the Others?

❌ Accumulation of dust: Dust may provide nucleation sites but doesn’t cause condensation.

❌ Absorption of sunlight: Dew forms at night when there’s no sunlight.

Fun Fact: Dew can provide critical water for plants in deserts! 🌱💧

Bonus: "Dew point" is the temperature at which dew forms. 🌡️
