Natural Systems A Level Geography AQA CCP p5 The Water Cycle(2)

..................... occurs when water vapour changes state to become a liquid and loses energy to its surroundings.

• Condensation

• Evaporation

• Sublimation

At what point does air containing water vapour change from a gas to a liquid?

• Change point

• Dew point

• Due point

When temperature drops at night heat is lost to space.

• True

• False

Water droplets can stay in the ................... by forming dew on leaves or other surfaces; or form part of a cloud which will float off with the winds.

• atmosphere

• cryosphere

• geosphere

The magnitude of the condensation flow depends on two factors

• the amount of water vapour in the atmosphere

• specific gravity

• the temperature

• the wind speed

.................. is the main flow of water from the atmosphere to the ground.

• condensation

• evaporation

• precipitation

When warm air cools down, water vapour condenses into water droplets and .............. are formed in the atmosphere. As the droplets get bigger they fall as precipitation.

• clouds

• dew points

• snowflakes

What are the three factors that cause warm air to cool and fall as precipitation?

• Other air masses

• Relief (topography)

• Convection

• Conduction

What form of precipitation is caused when warm air meets cool air and the warm air is forced above the cool air?

• Convective precipitation

• Frontal precipitation

• Orographic precipitation

When warm air meets mountains it is forced to rise, causing it to cool. This is known as ..........................

• convective precipitation

• frontal precipitation

• orographic precipitation
