In class today, Mr. Greg FINALLY was able to come in and show us a presentation on oil. He lectured and asked questions for several minutes, and then gave out worksheets for us. Down below is our work.
Oil Formation Video (My Cheat Sheet)
1) The process that forms oil requires a lot of time. How long ago did the oil we extract today start forming?
Two hundred million years ago.
2) What was the earth like at this time?
The continents had shifted around and turned out to be a big glob o' land. The rest of the earth was covered in water, but in the water, there was much, much more life forms than today, than now.
3) We call it oil now, but what was that slimy black stuff before it became oil?
Phytoplankton was used to create oil. They are plants with "bonds" of light. When you break that bond, you'll get that 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?
4.1) When phytoplankton die, they sink to the bottom.
4.2) They mix with other sediment and breaks down.
4.3) Other rock layers form on it, makes pressure and creates heat. (Heat is very vital to create this oil.)
4.4) Between 60 and 120 degrees Celcius, the oil is formed.
4.5) It "cooks" over two hundred million years to create oil.
5) Besides oil, what other fossil fuel can be formed by this process with only one minor variation?
If the heat goes up to / over 150 degrees Celcius, natural gas is created.
Bonus: But wait, we call oil a non-renewable resource. If we can just make more oil by this process, why do we call it "non-renewable"?
I'm thinking it's a non-renewable resource because you can't reuse it again. Once you've used the oil, you can't use it again for something else. It's just... against the laws of..... life.... and... nature... and possibly science..(?)
4) Continued: (More notes on this matter - Mr. Greg's words on creating oil)
Plants and Photosynthetic animals (diatoms)
The matter that makes fossil fuel.
Anoxic Environment
Required for chemical energy to be retained, avoiding decomposition.
Pressure
Concentrates plant and animal matter and generates heat.
Heat
Converts plant and animal matter to fossil fuel.
Capping Stone
Traps "lighter" (less dense) oil.
Time
Hundreds of Millions of Years

Some More Random Notes: (Thanks to Dasia's notes.)
Sedimentary Rock 1) Mud 2) Anoxic Environment 3) Heat 4) Time 5) Tada! You get Sedimentary Rock! |
Natural Gas 1) Biological Material Mud 2) Pressure 3) A LOT of Heat 4) Anoxic Environment 5) Capping stone 6) Time 7) Tada! You get Natural Gas! |
