The atmosphere. Weather and Climate

Fill in the Blank

The Earth's atmosphere reaches an altitude of approximately ___ km.

Multiple Select

Elements of the climate

• Atmospheric pressure

• Temperature

• Rainfall or Precipitation

• Wind

• Weather

Multiple Choice

The areas of high pressure are called

• Depressions

• Anticyclons

• Isotherms

• Isobars

Multiple Choice

Isobars are lines on a weather map joining together places of equal atmospheric pressure

• TRUE

• FALSE

• Not only do isobars tell us whether there is high or low pressure but they also tell us about wind:

• When the isobars are closer together the wind is stronger.

• When the isobars are further apart the wind is calmer.

Multiple Choice

Name one city in the UK experiencing high pressure

• Glasgow

• Rome

• Madrid

• London

Multiple Choice

Name one city in the UK experiencing low pressure.

• Glasgow

• London

• Rome

• Madrid

Multiple Choice

Which city on the map is experiencing the highest pressure?

• Glasgow

• London

• Madrid

• Rome

Multiple Choice

The atmospheric pressure in Lyon is

• 1016 mb

• 1028 mb

• 976 mb

• 1024 mb

Low pressure and depressions

An area of low pessure is called a depression:

• The low pressure or a depressions causes clouds and rainfall to form.

• Depressions therefore bring unsettled weather and rain.

• Winds are normally stronger, shown by the isobars being closer together.

• Depressions usually form over the Atlantic Ocean and move in an anticlockwise direction.

Low pressure and depressions

• You can recognise a depression on a weather chart:

• the isobars are below 1013mb and are packed closer together

• a warm front (red line) is followed by a cold front (blue line)

Multiple Choice

Low pressure is shown on an isobar map when the numbers are 1000mb or below.

• TRUE

• FALSE

Multiple Choice

Depressions will bring rain.

• True

• False

High pressure and anticyclones

A high pressure system is called an anticyclone.

• Air falls in an anticyclone so no clouds are formed.

• In summer, high pressure usually results in clear skies, gentle breezes and fine weather.

• In winter high pressure leads to clear skies and colder conditions.

• There is less wind as the isobars are further apart

• Anticyclones tend to move in a clockwise direction.

Multiple Choice

Anticyclones will bring rain.

• True

• False

Multiple Choice

High pressure is shown on an isobar map when the numbers are 1013 mb or below.

• True

• False

Multiple Choice

Winds will be calmer in an anticyclone.

• True

• False

Multiple Choice

Anticyclones move in an anticlockwise direction.

• True

• False

• You can recognise an anticyclone on a weather chart as the isobars are above 1013 mb and spread further apart.

• Anticyclones tend to last longer than depressions. For example, an anticyclone can last for two weeks whereas a depression lasts 2-3 days.

Multiple Choice

The air goes from the high pressure to low pressure zones

• TRUE

• FALSE

Multiple Choice

¿Cuál es la diferencia principal entre el clima y el tiempo atmosférico?

• El clima es el estado promedio de la atmósfera durante largos periodos, mientras que el tiempo es el estado momentáneo.

• El clima solo ocurre en las zonas tropicales y el tiempo en las zonas polares.

• El clima se refiere solo a la temperatura y el tiempo solo a la lluvia.

• El clima es más importante que el tiempo.
