What is the difference between weather and climate?


Climate is the overall pattern of weather, usually based

on an average over 30 years.

What is the difference between weather and climate?


The types of climate can be classified into 6 major zones.

World climate zones


What climate zone do you live in?

What other climate zones have you visited?

Climate can make a big difference to people’s holidays.

European climate


Anna, the travel agent at Travelstar

is having to deal with a difficult

customer. Mr Strattle is very keen

to go away on a city break in Europe.

However, Mr Strattle is very fussy

about things, especially the weather.

He does not want to travel to travel

anywhere where it might be cold and he

really dislikes rain when he is on holiday.

European climate


the holiday must take place in October.

he doesn’t want to visit a city where there

will be a high risk of rainfall.

he wants to visit a city with a reasonable

temperature–not too cold.

Mr Strattle has narrowed his choices down to four different

cities. Can you help Anna find a suitable destination for him?

Mr Strattle has decided that:

At first Anna looks at London.

However there is quite a lot

of rain in London during October.

Next Anna looks at Oslo. However,

Oslo has even more rain than London.

Warsaw does not seem to have much rain in October,

but the temperature might be too cold for Mr Strattle.

Eventually Anna finds a city that has a warm average

temperature in October and does not have too

much rainfall. Did you reach the same answer? Madrid

70% of the Earth’s surface is covered by water.

Store %

Oceans and seas 97

Snow and ice (mainly in the Arctic and Antarctic) 2

In the atmosphere or on the land as rivers and lakes 1

Water is neither created nor destroyed. It is cycled round

over and over again.

This recycling of water is called the water cycle.

Draw a graph to show where the Earth’s water is stored.

Precipitation is water from the atmosphere.

It can be in solid or liquid form.

There are three main types

of rainfall – relief,

convectional and frontal.

In all three situations, rainfall

occurs because air rises. Air

contains water vapour and

as the air rises it cools and

condensation can occur.

This means that the water

vapour returns back into

minute droplets of water and

falls as rain!

Why does it rain?


Convectional rain


Relief rain


Frontal rain

Weather and Climate Bingo!


Geographers study the weather because it has an impact on

people’s daily lives and the activities that they do.

Weather is the day to day changes in the atmosphere.

Climate is the overall pattern of weather, usually based on an

average over 30 years.

The British Isles has a temperate climate. This means that it is

not too hot, not too cold, not too dry and not too wet!

Water is neither created nor destroyed. It is cycled round over

and over again. This recycling of water is called the water cycle.

Precipitation is water from the atmosphere. It can be in solid or

liquid form.

There are three main types of rainfall – relief, convectional and

frontal. In all three situations, rainfall occurs because air is

forced to rise.
