Examine the diagram and decide which of the following statements is a logical conclusion for this diagram.
- A.
Peat is an altered organic matter, possibly from a historical swamp region.
- B.
The formation of anthracite takes time and pressure to convert once plant matter into a hard, dense energy source.
- C.
All forms of coal are excellent sources of industrial types of energy.
- D.
All forms of coal are black, dense forms of fossil fuels.
Correct Answer
B. The formation of anthracite takes time and pressure to convert once plant matter into a hard, dense energy source.Explanation
The diagram suggests that the formation of anthracite, a type of coal, requires time and pressure to convert plant matter into a hard and dense energy source. This conclusion is supported by the statement that peat, an altered organic matter, is possibly from a historical swamp region. It implies that over time and under pressure, the plant matter in the swamp region transformed into peat, and further transformation resulted in anthracite. Therefore, the given conclusion aligns with the information provided in the diagram.Rate this question:

Which of the following is NOT true about the formation of fossil fuels?
- A.
The formation of fossil fuels takes millions of years.
- B.
Heat and pressure allow organic matter to undergo change and carbonization to form fossil fuels.
- C.
Coal, oil, and natural gas are the remains of old, dead, organic matter buried and deposited in sedimentary rock.
- D.
The formation of fossil fuels is keeping up with the current rate of burning of these fossil fuels.
Correct Answer
D. The formation of fossil fuels is keeping up with the current rate of burning of these fossil fuels.Explanation
The formation of fossil fuels takes millions of years due to the process of heat and pressure allowing organic matter to undergo change and carbonization. Coal, oil, and natural gas are the remains of old, dead, organic matter buried and deposited in sedimentary rock. However, the formation of fossil fuels is not keeping up with the current rate of burning of these fossil fuels, as they are being consumed at a much faster rate than they can be formed.Rate this question:

If the amount of phytoplankton in the surface ocean water increases, what would happen to the amount of carbon in the atmosphere?
- A.
Increase
- B.
Decrease
- C.
No change
Correct Answer
B. DecreaseExplanation
When the amount of phytoplankton in the surface ocean water increases, it leads to an increase in photosynthesis. Phytoplankton absorbs carbon dioxide from the atmosphere during photosynthesis, thereby reducing the amount of carbon in the atmosphere. Therefore, if the amount of phytoplankton increases, the amount of carbon in the atmosphere would decrease.Rate this question:

Carbon in the atmosphere could eventually become a fossil fuel through land-based and water-based processes.
- A.
TRUE
- B.
FALSE
Correct Answer
A. TRUEExplanation
The statement is true because carbon in the atmosphere can be absorbed by plants through the process of photosynthesis, and over time, these plants can become fossil fuels such as coal, oil, and natural gas. Additionally, carbon can also be dissolved in water bodies and eventually become trapped in sedimentary rocks, forming fossil fuels through geological processes. Therefore, both land-based and water-based processes can contribute to the formation of fossil fuels from carbon in the atmosphere.Rate this question:
