Worked practice questions

When water vapour condenses directly into solid form, the process is:

  1. Precipitation
  2. Evaporation
  3. Sublimation
  4. Condensation
Show answer and solution

Correct answer: C. Sublimation

1. Normally vapour becomes liquid first. 2. Direct change to solid is sublimation. 3. Frost is an example of ice deposition. _Source: syllabus Fundamentals of Physical Geography, Chapter 11, Water in the Atmosphere._

Dew forms only when the dew point is:

  1. Below freezing point
  2. At zero exactly
  3. Above boiling point
  4. Above freezing point
Show answer and solution

Correct answer: D. Above freezing point

1. It needs clear sky, calm air and long cold nights. 2. The dew point must be above freezing. 3. Below freezing, frost forms instead. _Source: syllabus Fundamentals of Physical Geography, Chapter 11, Water in the Atmosphere._

Frost forms on cold surfaces when condensation occurs:

  1. Below freezing point
  2. Above freezing point
  3. Only at the dew point
  4. Only in free air aloft
Show answer and solution

Correct answer: A. Below freezing point

1. Moisture is deposited as ice crystals. 2. Frost needs condensation below 0 C. 3. Other conditions match those for dew. _Source: syllabus Fundamentals of Physical Geography, Chapter 11, Water in the Atmosphere._
