Managing Our Envoirnment

Question 1

What is the green house effect?

Answer 1

A Natural process whereby heat from the sun is trapped in our atmosphere by “greenhouse gasses”. Without it the earth would be 33 degrees cooler and would never be able to sustain life

Question 2

What is climate change?

Answer 2

Changes in the long term temperature. Precipitation patterns which increasing evidence suggests is caused by human activities

Question 3

What causes climate change

Answer 3

The release of greenhouse gases into the atmosphere that traps more heat in the earths atmosphere

Question 4

Definition of carbon footprint

Answer 4

A measure of the amount of carbon dioxide produced by a person, organization or a country in a given time

Question 5

Advantage and disadvantages of calculating carbon footprint

Answer 5

Consumers can easily grasp the impacts of what they are doing

It is difficult to calculate, especially when goods are imported from other countries

Question 6

Sunspot activity

Answer 6

Darker patches on the sun, these form at the areas where the magnetic field is particularly strong. The energy is so strong that it can keep some of the energy within the dun from reaching the surface

Question 7

The earths orbit

Answer 7

The earths orbit changes slightly between nearly circular and more elongated 100,000 years

Question 8

Volcanoes

Answer 8

Large volumes of sulphuric oxide, water vapor dust and ash into the atmosphere. These gases and dust particles particularly block the incoming rays of the sun, leading to cooling.

Question 9

Cars/human greenhouse effects

Answer 9

The exhaust of cars and lorries emit polluting gases, such as nitrogen dioxide which adds to green house emissions.

Question 10

Coal/human greenhouse effects

Answer 10

When coal, oil or gas is being burned in power stations to generate electricity it releases carbon dioxide which adds to the greenhouse effects

Question 11

Methane

Answer 11

Methane production from large number of cattle’s is increasing very quickly and so is nitrogen dioxide. This adds to the greenhouse effect

Question 12

Consequences of climate change

Answer 12

Sea levels rising - by up to 2m - due to thermal expansion. Could result in sea levels rising
Precipitation changes-rainfall will be more unreliable, could result in some places being wetter and some being drier. Could result in a change of climate in certain places
Tourism - snow in the alps may be less resulting in the reduction of conditions for skiers and having a negative effect on economy

Question 13

Agriculture

Answer 13

Types of crops, grown and their yields will be effected by the increasing of temps

Question 14

Health

Answer 14

Higher temps lead to greater risk of heat stroke and death

Question 15

Economy

Answer 15

Expensive flood protection. Schemes to protect coastal cities. Defend low lying cities and safeguard ports and hrbours

Question 16

What is a resource

Answer 16

A resource is anything that is useful to us

Question 17

What is waste management

Answer 17

Waste management is what we do with the waste society generates

Question 18

Waste hierarchy

Answer 18

Reduce
Reuse
Recycle
Dispose

The waste hierarchy shows how reducing, reusing and recycling materials can help prevent waste, increased reusing and recycling are good for the environment

Question 19

Ways to reduce waste

Answer 19

Turn off the tap when brushing your teeth
Read the newspaper online
Choose products with less packaging

Question 20

What is renewable energy

Answer 20

Energy from a source that is not depleted when used

Question 21

Examples of renewable energy

Answer 21

Solar energy
Wind energy
Hydro power
Ocean energy
Bio energy

Question 22

How is wind power captured

Answer 22

Turbines use blades to collect the winds kinetic energy

Question 23

Benefits of wind power

Answer 23

Good for the environment, doesn’t produce any carbon emissions
The wind farms use inexhaustible energy
Helps the uk be less dependent on non-renewable energy sources
Will produce energy relatively cheaply

Question 24

Disadvantages to wind farms

Answer 24

Can hard wildlife as wind turbines create their own electrical fields
Some people find wind turbines ugly and could potentially deter tourists as the do not want to see these from the coast line
Turbines take a lot of money to set up, walney wind farm cost over 10000000 to set up. However, it should give a constant return for over 20 years after with minimal maintenance
There has to be backup systems in case there is too little wind or the wind is too strong to operate safely

Question 25

Mass tourism

Answer 25

Mass tourism is large scale movements of people to tourist destinations and can have a negative impact on the relationship of the locals and the visitors

Question 26

Time

Answer 26

Increased leisure time lead to people having longer holidays

Question 27

Money

Answer 27

Increased disposable income along with shortened working week meant more money for less time

Question 28
