Oil Formation Video Notes
1. The process that forms oil requires a lot of time. How long ago did the oil we extract today start forming?
About 200 million years ago
2.What was the earth like at this time?
One mass continent (Pangaea) and one mass ocean.
3. We call it oil now, but what was that slimy black stuff before it became oil?
Phytoplankton
4. The video lists several processes or conditions required to change your answer to question 3 into oil. Can you list them all?
-Accumulates on ocean floor
-Mixes with other sediments & doesn't decompose
-Heat is generated from the pressure of new rock layers
-60-120 degrees Celsius = crude oil
150 degree Celsius & up = natural gas
-Dense sediment causes oil reservoir
5. Besides oil, what other fossil fuel can be formed by this process with only one minor variation?
Natural gas
