Level 1 Geography (Weather)

Which direction does air move?

• West - East

• High pressure to low pressure

• East - West

There are three main elements that make up weather. What are they?

• Heat, water and wind.

• Temperature, rainfall and air pressure.

• Wind, air pressure and precipitation.

• Air pressure, temperature and precipitation.

Air pressure is measure in millibars (mb). What is considered low air pressure?

• Below 1300 mb

• Below 1005 mb

• Below 1013 mb

• Below 1003 mb

Synoptic charts show us the air pressure an area is experiencing. These have lines on them that look similar to contour lines and show the pressure gradients. What are these lines called?

What happens to air pressure at high and low altitudes.

• Low air pressure at high altitudes and high air pressure at low altitudes.

• High air pressure at high altitudes and low air pressure at low altitudes.

• Air pressure is not affected by altitude so nothing happens.

• Areas near sea level experience high air pressure and mountainous areas experience low air pressure.

How is wind named?

• By the direction is travels towards

• By the direction it travels from

• By the area it travels over

• It is named randomly by weather presenters

What is that best description of a prevailing wind?

• A type of wind that can produce huge amounts of damage.

• Winds that always happen in the same way in the same place.

• Another name for a westerly wind.

• Winds that blow in a consistent direction over a particular region of the earth.
