Depressions

Depressions

Depressions

  • Depressions are low pressure areas which are caused when air rises.
  • The air rises because it is warmer than air around it or it can be forced up by high land.
  • As the air rises it cools and clouds form.
  • This causes unsettled changeable weather.
  • Depressions are often associated with fronts.
  • A front is where hot air is next to cold air.
  • The warm air is forced upwards, it cools and condenses causing clouds and rain.
