5.1 The DTM describes a
sequence of changes over
a period of time in the
relationship between birth
and death rates and
overall population change.
6.1 Tin is a heavy metal and it is found in igneous rocks. It is
recyclable and can be found in Cornwall, China and Indonesia.
6.2 Tin declined because of the high const of
extraction and low world prices making
extraction unprofitable. Tin deposits became
part of general resource stock.
6.3 In 2004, prices soared. Cornwall attracted
mining companies. 2007, south Crofty

7 Wind Energy
7.1 Wind energy is
increasing because it
is carbon neutral and
7.2 The best locations to harness this
energy is Rhane in France, Ebro in
Spain, Greece and Turkey.
7.3 The negatives of wind energy is that
manufacturing, transportation and
construction of turbines releases
8.1 Provides raw material for nuclear weapons.
Uranium 235. It was first used to colour
glass. We can control nuclear fission inside a
nuclear reactor to generate electricity. 17% of
world's electricity is powered through the
use of uranium.
9.1 Substitution: the use of
resources in place of
9.2 Beneficiation: upgrading of a resource
that was previously too costly eg.
9.3 Maximisation: use of a
variety of methods that
avoid waste and increase
production of a resource.

11.2 The Colordao River: source in Colorado,
mouth in Mexico. Divided into upper and
lower course in 1992.
11.3 The problems arising about the river's

11.4 CAP was the Central Arizona
Project. $4 billion investment to
divert water from the river.
Completed in 1992.
11.5 Stregies used to conserve water:
recycling water in industry, more
efficient toilet systems, changing from
highly water dependent crops to less
12.1 MEDC: low population growth but high
standard of living. Resource use
increases but technological advances and
recycling provide resource efficiencies.
12.2 NIC: rate of population
growth is declining but
to rapidly rising rates
of resource use.
12.3 LEDC: high rate of
but poverty is a
severe constraint on
13.1.1 Population increase -> demand for food -> increased mortality ->
decreased fertility -> decrease in population growth.
13.2 Anti- Malthusian's
13.2.1 Population increase -> demand for food -> improvement in
technology -> population growth continues.

fishery industry in the
commercial, social and

ownership of a resource leading to
over-exploitation. TACs have solved

14.4 Total allowable catches is a set
maximum quantity of fish that can be
caught each year.
15 Common Agricultural
15.1 Was introduced in the early
1960s, following a time when
Western Europe's agriculture
had been heavily damaged by
years of war and food supplies
could not be guaranteed. CAP
guaranteed minimum crop
prices and quotas on certain
15.2 2003 - The new "single farm
payments" are subject to
relating to environmental, food
safety and animal welfare
standards. The aim is to make
more money available for
environmental quality or animal
15.3 10 new countries joined the EU - they have a
greater dependency on farming as a source of
income and employment.
15.4 World trade organisation: heavily criticised CAP.
External tariffs denies LEDCs fair access to the
large EU food markets.
