natural gas

Question 1

occurence and extraction

Answer 1

• formed from decaying animal and plant matter that lived millions of years ago
• found underground, trapped in deep shale formations
• wells are drilled and due to the pressure of the pumped water the gas comes up to the surface and is pumped through pipelines
• refined to removes unwanted chemical impurities and then shipped in tankers
• Russia, Iran and Qatar have the largest reserves of natural gas

Question 2

uses

Answer 2

• industrial
• electric generation
• residential
  -commercial

Question 3

advantages

Answer 3

• cleaner fuel producing fewer carbon emissions than coal or oil
• does not produce waste and disperses quickly in case of leaks
• allows quick results and precise control
• more abundant than other fossil fuels
• easy to distribute and transport

Question 4

disadvantages

Answer 4

• produces greenhouse gas emissions that contribute to enhanced greenhouse effect
• finite resources - cannot become reliant on it
• if inhales, the gas is toxic and colorless so cannot be easily detected
• storing gas is more expensive due to larger volume
• pumping of gas and fracking increases tectonic activity

Question 5

peru

Answer 5

• Camasea project was launched in 2004 to extract natural gas in the Amazon
• predicted to save Peru $4 billion in energy costs
• this came at the expense of the lives of indigenous tribes who lived in the area
