Primary Economic Activity Flashcards
Renewable Resources
Can be used over and over. Eg. Water
Non-renewable resources
Will eventually run out. Eg. Oil
The water cycle
Evaporation,Condensation,Precipitation,Run-off.
Primary Economic Activity
Farming,Fishing,Forestry,Mining
Oil
Non-renewable resource and we need to try to conserve the oil we gave
Oil producing country

Gas and Oil in Ireland
The is not much yet we are exploring the coastline

Irrigation
Irrigation is used when an area is in drought. It is a supply of water that is piped to the area that needs fresh water.
Over-exploitation
Using to much of a resource.
Depletion
Stocks of fish get used up.
Continental shelf
Area around the coastline
Renewable energy sources
Geothermal energy, tidal energy, solar energy, wind energy, hydro electric power.
Geothermal energy
Created by pumping cold water into the earths crust. Results in steam and hot water.
Tidal energy
The power of the rising and falling tides can be used to turn turbines. This tidal energy creates electricity.
