Making geographical descisions Flashcards
What are the three energy resources?
non renewable
renewable
recyclable
What is recyclable energy resources?
for example, biofuels and nuclear power
What are the negatives of hydroelectric dams?
They flood all the land behind the dams
What are the negatives of recyclable energy resources like nuclear power and biofuels?
- nuclear waste cant be easily disposed of
- risk of accidents and nuclear meltdowns
- biofuels take up a lot of room to be grown where food could be grown instead
- deforestation occurs because biofuels are grown instead
Why does distribution of the amount of energy used per person vary?
- Some countries have a high amount of natural resources which can be used for energy. e.g. Iceland has access to geothermal energy, Saudi Arabia has access to high amounts of oil
- some countries are more developed than others and hence have more money, richer people tend to use more energy for technology and manufacturing.
- some countries people cant afford to have cars or gas cookers
Why is oil consumption rising?
- increasing population
- as countries get richer, people buy more things which require increasing amount of energy
- as new technology is developed e.g. iPhones, people want the latest one and the companies want you to buy the newest product
- increased manufacturing/consuming
- increased amount of people with cars
What are 3 examples of renewable energy?
- solar
- wave
- wind
- water
- HEP
- Geo power
- tidal
What are natural sources of carbon emissions?
- respiration
- decomposition
- volcanoes
- some combustion
What are the negative environmental impacts of Wind turbines and solar panels?
- non renewable energy used to make them
- wind turbines could affect marine life
What are the negative environmental impacts of open cast coal mining?
- destroys habitats
- scars landscape
- non renewable
- produces carbon emissions
- chemical leaks
- deforestation
What are the negative environmental impacts of drilling for oil at sea?
- oil leaks kills animals
- non renewable
- increases carbon emissions
- carbon emissions produced in shipping
- oil rigs are expenisive
What are the negative environmental impacts of HEP?
- floods land:
- destroys villages, crops, habitats and spreads disease
- deforestation
- changes fish habitats
How is coal formed in the UK?
Most of the coal was formed in the carboniferous period when giant tropical plants in swamps decomposed and over time, the pressure turned it into coal
What are the advantages of exploiting coal in the uk?
- lots of coal in the uk that can be sold or used for energy
- create lots of jobs
- boosts the economy
- income for the government
- less imported energy stores
What are the negative impacts of exploiting coal in the uk?
- very deep coal, expensive and energy consuming to mine
- non renewable so will run out
- carbon emissions
- damage the environment and wildlife
