Geography Flashcards
Evaporation
Process of liquid water becoming water vapour due to heating. Normally the sun
Condensation
Process of water vapour becoming a liquid water again. Occurs due to cooling, often at altitude to form clouds.
Precipitation
Any form of water falling from the sky. Most commonly rain but can be snow, hail or sleet
Weather
The climatic conditions of a place right here and right now. Varies very quickly
Climate
The average weather conditions for a particular place over 30 years or more
Microclimate
The climate of a small area which is different to its general surroundings
Water surplus
When an area has more water available than it actually needs to use
Water deficit
When an area has less water available than it actually needs to use
Tidal power
Way of generating electricity renewably by using the power of rising and falling tides
Hydroelectric power
Turbines in a dam generate electricity as water is released from the reservoir behind
Kielder water
Large reservoir in Northern England from which water is transferred to the south where there is water deficit
Cholera
A water born disease which is common in areas which lack a clean water source
Transpiration
Water vapour released by plants as they respire. This can rise and form clouds
Saturated ground
Soil which is already full of water and therefore cannot absorb any more if further rainfall occurs
Population density
A measure of how crowded somewhere is, expressed as people per km2
Sparsely populated
An area with a low population density
Densely populated
An area with a high population density
Birth rate
The number of babies born per 1000 people
Death rate
The number of deaths per 1000 people
Population pyramid
A graph that shows the percentage of males and females within different age groups
Economically active
People who work
Young dependents
