2. The relationship between climate and
vegetation
Characteristics of the major types of natural
vegetation in the world
Describe and compare the sub types of
vegetation
Benefits of natural vegetation to people
3. Plants which are grown naturally and not
done by man.
Forests, Grasslands & Desert Vegetation
13. Remember: Rainfall and Temperature, and
differences between amount of sunlight.
Climate Vegetation relationship
14. Large areas of land that consist mainly of trees
and a variety of other plants
Types of forests differ according to different
climates
Geog. Textbook pg. 159
15. Thrives in warm tropical climates, with
temperatures of 20°C to 30°C. Also has rainfall
ranging from 1000mm to 2000mm
16. Characteristics of tropical rainforests
Evergreen
Trees have waxy drip tip leaves
Trees have broad leaf surfaces to absorb as muh
sunlight as possible.
Trees grow very close to one another, making it
dense in nature
17. Three layers of tropical rainforests
Emergent, Canopy, Undergrowth
18. Undergrowth
Made of shrubs, grasses, ferns, mosses and fungi
Plant growth is sparse because very little sunlight
reaches this layer.
19. Canopy
Tall trees reaching a height of 15 to 30 metres
Crowns of trees interlock to form a continuous
leaf cover
Canopy blocks out 70 to 100 percent of sunlight.
20. Emergent
Height of 40 to 50 metres
Trees receive more sunlight at this layer and have
buttress roots for support
21. Occurs largely in temperate regions
Two main types:
Temperate Deciduous Forests
Temperate Coniferous Forests
22. Vegetation thrives in temperatures from -2°C
to 18°C and rainfall ranging from 750mm to
1800mm
Vegetation has leaves where it falls off to
prevent water loss, in times where there is
little water
23. Properties
Nature of layers change across the seasons.
Read pg. 167 (Questions will be asked from
there!!!)
24. Found in places where temperatures range
from -12°C to 10°C. Rainfall at 300mm to
750mm
Called coniferous due to it’s conical shape.
Questions will be asked from textbook pg. 168
25.
26. Two types of Grasslands
Tropical Savannah
Temperate Grasslands
Occurs in areas where rainfall is seasonal in
nature.
27. Found in places in the tropics
Characterised with tall grasses along with
scattered trees.
Trees have large trunks to help store water.
28. Trees have small leaves to prevent water loss
through Transpiration
29. Found in seasonal climates, which can be very
hot in summer and cold in winter.
Dry climate with strong winds
Temperatures range between -20°C and 10°C
30. Grasses tend to be shorter due to lack of
rainfall.
Trees are scarce.
31. Hot Desert Vegetation and Cold Tundra
Vegetation
Desert Vegetation has very little leaves
Can occur at temperatures of -30°C to 45°C
depending on climate
32. Vegetation tend to have fleshy stems like for
example cactus
Hot desert plants have long roots
Desert plants have shorter life cycles
33. Temperature rarely rises above 0°C, with little
rainfall all year round.
Mostly snowing rather than rain.
