This is how natural gas is formed:
1) At one time Alberta was covered by water.Over time millions of tiny plants and animals died and were slowley covered by layers of sand and silt.
2) Over millions of years the dead plants and animals are buried deeper and deeper, then the heat and pressure of the sand and silt turned them into natural gas.
3) Today we remove the natural gas, to learn how go to the page "How is natural gas removed from the ground"
