The video tutorial explains the processes of evaporation and condensation, which lead to rainfall. It describes how water changes into vapor due to heat and forms clouds through condensation. The water cycle is highlighted as a continuous journey of water from the earth to the sky and back. The sun's role in this cycle is emphasized, showing how it drives evaporation and rainfall, replenishing water bodies.

What are the two main processes involved in the formation of rain?

• Evaporation and Precipitation

• Precipitation and Transpiration

• Condensation and Transpiration

• Evaporation and Condensation

What happens to water when it is heated by the sun?

• It remains the same

• It turns into ice

• It evaporates

• It condenses

Why do wet clothes dry faster in summer than in winter?

• Because of wind

• Because of higher humidity

• Because of lower temperature

• Because of higher temperature

In the towel drying experiment, why does the unfolded towel dry faster?

• Because it is exposed to more sunlight

• Because it is thinner

• Because it is lighter

• Because it has a larger surface area exposed

What is the process called when water vapor cools down and changes into tiny droplets of water?

• Evaporation

• Precipitation

• Condensation

• Transpiration

What happens to water vapor when it rises up into the sky?

• It meets cool air and condenses

• It evaporates further

• It disappears

• It turns into ice

What causes clouds to become heavy and eventually release rain?

• Too much sunlight

• Too much evaporation

• Too much wind

• Too much collection of water droplets

What is the continuous journey of water from the land to the sky and back called?

• Water cycle

• Evaporation cycle

• Condensation cycle

• Precipitation cycle

What role does the sun play in the water cycle?

• It cools down the water

• It evaporates water from the earth's surface

• It forms clouds

• It condenses water vapor

What happens to water after it falls as rain?

• It disappears

• It turns into ice

• It evaporates immediately

• It fills up oceans, rivers, lakes, and ponds
