"The wearing away and redistribution of the Earth’s soil. It is caused by the action of water, wind and ice, and also by unsustainable methods of agriculture (and deforestation)" is the definition for which key term?
Desertification
Soil erosion
Deforestation
Run off
"Destruction of forest for timber, fuel, charcoal burning, and clearing for agriculture and extractive industries, such as mining. It causes fertile soil to be blown away or washed into rivers, leading to soil erosion, drought, flooding and loss of wildlife" is the definition for which key term?
Deforestation
Desertification
Pollution
Climate change
Is soil renewable?
Yes it can be made over and over again
It is infinite
No it is considered finite as it takes much longer than human lifetimes to form any depth.
It is renewable
Which of these are causes of soil erosion?
Deforestation
Agricultural mismanagement
Urbanisation
Overpopulation
What is "sustainable development"?
People meeting their needs through economic development
Conservation of resources
Economic development in LICs
A carefully calculated system of resource management which ensures that the current level of exploitation does not compromise the ability of future generations to meet their own needs.
How does terracing prevent soil erosion in agriculture?
They are for growing rice.
The growing area/field is levelled off and stone or other barriers stop soil running downhill.
There are water buffalo that hold the soil in place.
They move left and right to maintain a constant altitude, which reduces runoff.
What is causing enhanced global warming?
Solar flares
Release of too many greenhouse gases into the atmosphere from economic activities
It is natural climate change
Ozone layer depletion
Which of these are NOT greenhouse gases
Methane
Ozone
Particulate matter
CO2
Oxygen
Tick all of these that are impacts of global warming:
Melting of glaciers and polar ice caps
Running out of oil
Sea level rise
Spread of tropical diseases to higher latitudes
Increasing ocean acidity
How many people died in 2016 from outdoor air pollution?
70 million
7 million
700,000
700
What does "transboundary pollution" mean?
Ozone layer depletion
Air pollution
Pollution of boundaries
Pollution which crosses international borders
Tick all of the following that are air pollutants:
Soil
Carbon monoxide
VOCs
Ozone
Nitrogen dioxide
Tick all of these that are major sources of water pollution:
Sewage
Particulate matter (PM)
Agricultural runoff
Chemical and oil spills
Nitrogen dioxide
What is resource conservation?
Protected areas
Landfilling everything
The protection and rational use of our resources
Installing incinerators to turn waste into energy
What are the three major environmental problems in the Pearl River Delta?
Air pollution, water pollution, deforestation
Running shoes, artificial Christmas trees and microwaves
Overpopulation, agriculture and sewage
Urbanisation, runoff and particulate matter
