Olaf in the atmosphere

The movement of matter and energy in the atmosphere causes atmospheric

phenomena, such as:

• air , condensation, water vapour and precipitation

• wind, condensation, water vapour and precipitation

• wind, fog, water vapour and storms

Wind...

• is a cloud which is

  near the Earth’s surface It occurs when low

  temperatures cause water

  vapour to condense near the ground.

• occurs when water

  vapour condenses on a

  surface such as a leaf.

  It occurs at night when

  temperatures are lower.

• form when

  water vapour rises and

  condenses into water

  droplets or ice crystals

  that are light enough to stay in the sky.

• occurs when

  dew freezes because

  temperatures are below

  0 °C. It often occurs on

  cold, clear4 nights

• is the

  movement of air from areas where

  the air is colder and denser to areas

  where the air is warmer and lighter.

Clouds...

Precipitation....

• is a cloud which is

  near the Earth’s surface It occurs when low

  temperatures cause water

  vapour to condense near the ground.

• Water (liquid or solid) falling from the atmosphere.

  Droplets of water vapour inside clouds collide and join together forming

  larger drops. When they’re too heavy to stay in the air, the drops fall to

  the ground.

• form when

  water vapour rises and

  condenses into water

  droplets or ice crystals

  that are light enough to stay in the sky.
