P5 Water Cycle

Name the process when water is heated in the ocean and turns into water vapour.

• Condensation
• Evaporation
• Melting
• Freezing

Name the process when water vapour is cooled to form water droplets

• Evaporation
• Condensation
• Melting
• Freezing

If water was heated by a hot plate to model the water cycle, the hot plate represents...

• Wind
• Moon
• Sun

Which one of these statements about evaporation is correct?

• Seawater evaporates into water vapour which is invisible
• Water from the river evaporates into water droplets
• Water from the sea evaporates to form water vapour
• Evaporation only takes place at high temperatures

How are clouds formed?

• Water vapour accumulated in the sky to form clouds
• Water droplets lost heat to cooler surrounding air & condensed into clouds
• Water vapour lost heat to cooler surrounding air & condensed into clouds
• Water droplets gain heat from the cool surrounding air & condensed into clouds

The increase in the amount of heat, wind and exposed surface area are factors that speed up which process? 

• Evaporation 
• Condensation
• Freezing
• Melting

With greater difference in temperature between the water vapour & the cooler contact surface...

• the rate of evaporation will increase
• the rate of condensation will increase
• the rate of condensation will decrease

The water cycle has no start or end

• True
• False
