oil and gas
1. The process that forms oil requires a lot of time. How long ago did the oil we extract today start forming?
> 200 million years
2. What was the earth like at this time?
> The land was like one big blob and the rest of the area was water.
3. We call it oil now, but what was that slimy black stuff before it became oil?
> Phytoplankton was used to create oil.
4. The video lists several processes or conditions required to change you answer to question three into oil. I can think of five - can you get them all?
> 1. Phytoplankton die and sink into the ocean
2. They mix with other sentiments
3. Rock layers on top of it and generates heat
4. Between 60 and 120 degrees Celsius, oil is formed
5. It boils over 200 million years and creates oil
5. Besides oil, what other fossil fuel can be formed by this process with only one minor variation?
> Over 150 degrees Celsius, natural gas is formed.
Continued Notes
Plants and photosynthesis animals (diatoms)
> matter that make up the fossil fuel
Anoxic environment
> required for chemical energy to be retained, avoiding decomp.
Pressure
> concentrates plant and animal matter & generates heat
Heat
> converts plant and animal matter to fossil fuel
Capping Stone
> traps "lighter" oil
Time
> 100's of millions of years
> 200 million years
