geography unit 1 Flashcards
Kyoto protocol
-climate change
A international agreement that aims to reduce the carbon dioxide
Carbon credits
Climate change
Selling the the amount of co2 left over
Emissions trading
Climate change
Trading their co2
Carbon sinks
Climate change
Planting tress to absorb the co2 eg Amazon rainforest
Greenhouse effect
Climate change
The warming of the earths atmosphere by the releases of gasses eg Meghan carbon dioxide
Green house gases
Climate change
Any of the gases that contribute to the greenhouse eg methane ch4,carbon dioxide co2,water vapour and nitros oxide no2
Global warming
Climate change
The increase of the average temperature due to carbon dioxide and other gases due to burning fossil fuels
Long wave radiation
Climate change
Heat reflecting from the earths surface
Short wave radiation
Climate change
Energy from the sun
Keeling curve
Climate change
A graph showing the co2 in the earths surface since 1958
Ippc
Climate change
International panelon climate change
Climate
Climate change
The average weather conditions over a period of time
Weather
Climate change
The state of the atmosphere
Storm surge
Climate change
Rapid rise of sea level
Drought
Climate change
Long period of dry weather
Water stress
Climate change
Fresh water resources
Sustainability
Climate change
Meeting the needs of today’s population without the needs of further generations
Biofuels
Climate change
Any kind of fuel manufactured from living things or waste
Clean energy
Climate change
Also known has renewable energy
Energy that comes from resource which are naturally replenished eg rain,tidal
Carbon neutral
Climate change
Removing co2 from the atmosphere as we put it in
Collision margin
Hazards
Plates moving towards eachother
Both plates pushed up forming fold mountains eg Himalayas
Conservative margin
Hazard
Plates slides passed eachother
Friction overcomes and plate slip past in a sudden movement
Causing earthquake
Constructive margin
Hazards
Plates move apart
Volcanoes are formed as magma fills the gap and eventually new crust is formed
Destructive boundary
Hazards
Two plates move together Heavier plate gets pushed underneath and plate melts due to high temperatures Lots of friction causing earthquake Magma rises to form a volcanic eruption Land forms like volcanic island eg Java
Crust
Hazards
The thin outer layer of the earths surface made of rock
Earthquake
Hazards
The shaking of the earths surface caused by rock movement
Epicentre
Hazards
The point on the ground directly above the focus of an earthquake
Fold mountains
Hazards
Formed when 2 tectonics plate that move towards eachother
Geothermal energy
Hazards
Energy from the hot rock,water is pumped down to the rock and turned into steam. Can be used to heat homes or make electricity. A lot of pollution
Island arc
Hazards
A group of volcanoes usually situated in a curving arch
Lahar
Hazards
Hot or cold mixture of water and rock fragments that flow down a volcano slopes
Lava
Hazards
Melted rock that erupts from a volcano
Magma
Hazards
Melted rock below the earths surface
When reaches the surface it’s called lahar
Mantle
Hazards
The middle layer of the earth between the crust and core
Metamorphic rock
Hazards
Formed from outer rocks that are changed because of heat or pressure
Plate margin
Hazards
When oceanic and continental plates move together
Plate tectonics
Hazards
The structure of the earths crust
