Worked practice questions

Which energy source mainly powers the water cycle?

  1. Pull of the Moon
  2. Winds of the tropics
  3. Heat of the Earth's core
  4. Heat from the Sun
Show answer and solution

Correct answer: D. Heat from the Sun

1. The Sun heats water in oceans, lakes and rivers. 2. This heat drives evaporation, which starts the cycle. 3. Wind, the core and the Moon do not power the cycle itself. _Source: Wikipedia, Water cycle, Overall process_

Which process turns water vapour into droplets that form clouds and fog?

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

Correct answer: D. Condensation

1. Condensation changes water vapour into liquid droplets. 2. These droplets gather as clouds and fog. 3. Evaporation and transpiration add vapour instead of removing it. _Source: Wikipedia, Water cycle, Overall process_

What do we call the release of water vapour from plants into the air?

  1. Advection
  2. Precipitation
  3. Percolation
  4. Transpiration
Show answer and solution

Correct answer: D. Transpiration

1. Plants lose water vapour through their leaves. 2. This release is called transpiration. 3. Precipitation is falling water, percolation is downward seepage and advection is movement in air. _Source: Wikipedia, Water cycle, Overall process_
