  • condensation
  • sublimation
  • saturation

  • 2. 
    What is the energy required to change water's state or phase, without changing its temperature called?

  • Latent heat of the Earth
  • Latent heat of the water
  • Latent heat of the rock
  • Latent heat of the atmosphere

  • 3. 
    ______ is frozen raindrops and refrozen melted snow-water.

  • Sleet
  • Frost
  • Cloud
  • Mist

  • 4. 
    When air containing water reaches its saturation point, then

  • No more water evaporates from the ground
  • It leads to evaporation above sea and precipitation above land.
  • Water vapour forms droplets
  • The droplets fall out of the clouds

  • 5. 
    The percentage of moisture present in the atmosphere as compared to its full capacity at a given temperature is known as the

  • Relative humidity
  • Specific humidity
  • Absolute humidity
  • Saturated air

  • 6. 
    The air can only contain a certain amount of water vapour before it is saturated. This amount is dependent on

  • the temperature of the air
  • whether the air is above sea or land
  • the wind speed
  • the amount of dust particles in the air

  • 7.

  • plains
  • valleys

  • 8. 
    The alto clouds are found at

  • mid-levels
  • low levels
  • low, mid, and high levels

  • 9. 
    When the water containing air becomes saturated, then

  • it will be calm
  • it will be windy above sea and rainy above land
  • it will start to rain
  • clouds will be formed

  • 10.
