Chapter 10: Water in the Atmosphere — Important Questions & Answers
What is the water vapour present in the air called?
- A. Atmospheric moisture
- B. Precipitation
- C. Condensation
- D. Evaporation
Answer: A. Atmospheric moisture
Water vapour in the atmosphere is known as atmospheric moisture. It is an important component of weather and climate.

Which process changes water from liquid state into water vapour?
- A. Condensation
- B. Evaporation
- C. Precipitation
- D. Freezing
Answer: B. Evaporation
Evaporation is the process by which liquid water changes into water vapour. It mainly occurs from oceans, rivers, lakes and moist land surfaces.

In the hydrological cycle, what is the main source of water vapour in the atmosphere?
- A. Melting of glaciers
- B. Evaporation from water bodies and land surfaces
- C. Formation of clouds
- D. Rainfall on mountains
Answer: B. Evaporation from water bodies and land surfaces
Most atmospheric water vapour comes from evaporation from oceans, seas, lakes and other moist surfaces. This is a key part of the hydrological cycle.

A city near the coast has high humidity throughout the year. Which outcome is most likely?
- A. Very rapid evaporation all the time
- B. Air can hold more water vapour than usual
- C. Slower evaporation compared to dry regions
- D. No cloud formation
Answer: C. Slower evaporation compared to dry regions
High humidity means the air is already close to saturation, so evaporation slows down. Coastal regions often experience moist air and cloud formation.

Which statement is most accurate about the relationship between humidity and the possibility of rain?
- A. Low humidity always causes rain
- B. High humidity alone is enough for rain to occur
- C. High humidity increases the chance of condensation, but additional cooling and uplift are needed for rain
- D. Humidity has no role in rainfall
Answer: C. High humidity increases the chance of condensation, but additional cooling and uplift are needed for rain
High humidity means air contains a lot of moisture, which supports condensation. However, rain usually needs cooling, uplift and cloud development before precipitation occurs.
