Climate Change Flashcards
The deliberate planting of trees on otherwise bare land. Afforestation can create new habitats for wildlife, stabilise souls and prevent surface run-off.
Afforestation
The growing of both trees and agricultural/horticultural crops of the same piece of land.
Agroforestry
An organic compound.
Chlorofluorocarbons (CFCs)
The long-term alteration of weather patterns.
Climate change
An area where people are charged to take their cars into a city centre.
Congestion charge zone
The practise of growing different crops in succession on the same land chiefly to preserve the productive capacity of the soil.
Crop rotation
The cutting down of trees and forests to allow a different land use.
Deforestation
A river landform made of deposited sediment at the mouth of a river.
Deltas
A long period of low rainfall that creates a major shortage of water.
Drought
People who work towards or advocate the protection of the environment from destruction and pollution.
Environmentalists
The rise in the average temperature of the Earth’s surface.
Global warming
The retention of heat in the atmosphere caused by the build up of greenhouse gases.
Greenhouse effect
The gases responsible for global warming - carbon dioxide, methane, nitrous oxide and CFCs.
Greenhouse gas
An organisation set up between government to monitor the causes, effects and management of climate change.
Intergovernmental Panel on Climate Change
At the United Nations conference in Kyoto, Japan 1997, MEDC governments pledged to reduce emissions of greenhouse gases.
Kyoto Protocol
The quality of land and soils are lower in quality.
Land degradation
To move from one area, country or region to another.
Migrate
Over farming which can cause a lack of nutrients in the soil, fertilisers are often required.
Over cultivation
Huge areas of land cleared for cattle.
Overgrazing/cattle ranching
A layer of gas in the atmosphere that protects the Earth from harmful radiation from the sun.
Ozone layer
Moisture that falls from the air to the ground. Includes rain, snow, hail, sleet, drizzle, fog and mist.
Precipitation
Rather than a whole area of trees being cleared, only single may require trees are felled leaving young trees to grow.
Selective tree felling
The energy received from the sun.
Solar energy
Energy from the sun - consisting of visible light, heat or infra-red radiation, ultra-violet and other forms of radiation.
Solar radiation
The successor of the League of Nations, the UN was established in 1945 as an international organisation designed to keep peace, uphold international law and set standards in human rights.
