Describe the distribution of major biomes across the planet

Battle for the Biosphere Part 1:
What is the value of the Biosphere?
Tropical Rainforests: In a band north and south of the Equator as the sun’s rays
are concentrated here and there is heavy rainfall.

Battle for the Biosphere Part 1: What is the value of the Biosphere?
I know the distribution of major biomes across the planet
I understand How climate (temperature and precipitation)
influences the distribution and types of biomes
I know how Local Factors effect vegetation
I know How the biosphere provides important good and
services to humans.
I know How goods and services support human life on
Earth
I am okay
with this,
some work
needed
Definitely
need
more
revision
How the biosphere provides important good and services to humans.
SERVICES = things that satisfy our needs
1. Regulating the composition of the
atmosphere – forests remove carbon
dioxide from the atmosphere reducing
global warming. Forests give out oxygen –
purifying the atmosphere
2. Maintaining the health of the soil –
forests provide leaf litter which forms
humus. This makes the soil more
fertile for growing crops
3. Regulating water within the hydrological
cycle – forests protects watersheds from
soil erosion and intercepts precipitation –
preventing flash flooding. They also trap
silt therefore keeping the water pure.

GOODS = things of value to us
Food
fish and meat
Sustainable harvesting of fruits, nuts and
berries
Raw materials
Timer
Bamboo – used in Hong Kong for scaffolding
wood pulp makes paper
Medicine
Vitamin C is found in oranges
St John’s Wort is a plant used to help treat
depression
the periwinkle plant is used to treat
Hodgkin’s disease
How goods and services support human life on
Earth

 In Britain, deciduous forest wood helped
make and fuel the factories that drove
the industrial revolution.
 Tropical rainforests are vital for poor
countries in South America where wood
is used in many ways to help build local
incomes.
 Coniferous forests in North America
provide much of the world’s softwood
which is used to make paper
