Which of the following factors primarily determines the type of fossil fuel (coal, oil, or natural gas) that forms from ancient organic matter?
A
The altitude at which the organic matter is buried
B
The type of organic material, temperature, pressure, and length of time buried
C
The amount of sunlight the area receives
D
The presence of volcanic activity nearby
Verified step by step guidance1
Understand that fossil fuels are formed from ancient organic matter that undergoes chemical and physical changes over time due to environmental conditions.
Recognize that the type of organic material (e.g., plant matter or marine organisms) plays a key role in determining the type of fossil fuel formed. For example, coal typically forms from plant material, while oil and natural gas often form from marine organisms.
Learn that temperature and pressure are critical factors in the formation process. Higher temperatures and pressures can lead to the formation of oil and natural gas, while lower temperatures and pressures favor coal formation.
Consider the length of time the organic matter is buried. Longer burial times allow for more extensive chemical transformations, which can influence the type of fossil fuel produced.
Understand that external factors like altitude, sunlight, and volcanic activity are not primary determinants of fossil fuel type. The correct answer focuses on the type of organic material, temperature, pressure, and burial time as the main factors.
