Question 2

non renewable energy form continuously but slowly. what are some examples

Answer 2

fuels (coal, oil, natural gas)
metals (iron, copper, uranium, gold)

Question 3

what is an oil trap

Answer 3

a geologic environment that allows economically significant amounts of oil and gas to accumulate underground

Question 4

what is a reservoir rock

Answer 4

a porous and permeable rock that contains petroleum and natural gas

Question 5

whats a cap rock

Answer 5

impermeable to oil and gas, prevents it from escaping

Question 6

hydraulic fracturing – also called fracking. what is this

Answer 6

• huge quantities of oil can be trapped in impermeable rock
• fluids (mixture of water, sand and chemicals) are pumped into the impermeable rock at high pressures
• opens cracks and keeps them open for gas and oil to flow up to the surface
• can trigger minor earthquakes and cause groundwater contamination
