1

Explain how latitude influences a climate

The Distance North or south of the equator
In general, the higher the latitude, the colder it will be

2

Explain how distance from the sea or ocean influences a climate

Water in the sea absorbs heat very slowly in the summer and loses it slowly in the winter. Therefore, areas of land close to the water will be cooled in the summer and warmed in the winter and has a very small temperature range. Land absorbs heat quickly in the summer and loses it quickly in the winter so inland areas are warmer in the summer and cooler in the winter.

3

Factors that influence a climate

Latitude
Distance from the sea/ocean
Prevailing winds and air masses

4

Explain how prevailing winds and air masses influence a climate.

Winds can make and area colder, warmer,wetter or drier
Their influence will depend on the direction from which they come and whether they pass over wind or water. (Winds and air masses)

5

Northerly winds

Cold
Generally dry

6

Easterly winds

Warm in the summer
Cold in the winter
Usually dry

7

Southerly winds

Warm
Some rain

8

South-westerly winds

Cool in summer
Mild in winter
Rain bearing

9

What is a local climate?

The climate experienced by a small region

10

Factors which influence a local climate

1.Aspect
2.Altitude

11

How does aspect affect a local climate?

Aspects refers to the different direction in which a slope is facing eg.North/South
In the northern hemisphere, south-facing slopes are warmer. why?
1.The sun shines directly on them
2.Warm,southerly winds blow against them
3.protected from cold northerly winds

12

Explain how altitude is a factor affecting local climate

Altitude refers to height above sea level
In general,the higher the altitude, the lower the temperature
The temperature drops 7°C every kilometer you go up.Why?
1.air is thinner and can hold less heat
2.Upland areas are more exposed to heat 'wind chill factor'

13

What is a natural region?

An area of the word which has its own unique characteristics that make it different to other areas:
Climate,Natural Vegetation,Wildlife,Human activities

14

The 3 groups of world climates

Hot climates
Temperate climates
Cold climates

15

Climates in the group 'hot climates'

Equatorial
Savanna
Hot desert

16

Climates in temperate climates

Cool temperate
Warm temperate

17

Climates in cold climates

Boreal
Tundra

18

Where are Hot climates found?

Near the equator, from 30°N to 30°S

19

Explain Equatorial climate briefly

Hot all year (28°C)
One season
Rain every afternoon
Rainfall of 2000mm/yr
Rainforest/Jungle

20

Explain Savanna climate briefly

Hot all year (25-35°.)
Two seasons
Wet in the summer
Dry in the winter
Scattered trees/grassland

21

Explain Hot Desert climate briefly

Day (30-50°C)
Night (5°C)
Rainfall is 100mm/yr
Long droughts
Followed by downpours of rain

22

Why is difficult for plants and animals to survive in the desert?

Because of the lack of water

23

Explain how the cactus have adapted to the hot desert

Thick bark prevents loss of moisture
Can store water inside of it
Roots spread a long distance to reach nearest available water
The needles protect it from wild animals

24

Explain how the camel has adapted to the hot desert

Eyelashes to protect their eyes
Nostrils that can open and close
Thick skin on legs to protect from hot sand
Can store fat in humps for when food is scarce

25

What is oasis?

A fertile area in a desert where water is found close to the surface

26

Temperature in a cool temperate oceanic climate

Warm summers (15-17°C)
Mild winters (4-6°C)

27

Cool temperate oceanic climate rainfall

Rainfall throughout the year, mostly in winter
(800-2000mm)

28

Cool temperate oceanic climate vegetation

Deciduous forest:oak,ash,elm,willow
Most are removed for farming, transport and settlement

29

Warm temperate oceanic climate summer

Summer's are hot and dry, 30°C. Dry and some drought
-close to the equator, so the sun is high in the sky
-cloudless skies allow long hours of sunshine
-trade winds that blow over dry land masses

30

Warm temperate oceanic climate is aka?

The medetaranian climate
