On Level: Formation of Fossil Fuels

A student is building a model to demonstrate how fossil fuels form over millions of years. The model includes a container filled with layers of sand and dead plant material, sealed with a lid. A weight is placed on top of the lid. Which process is being demonstrated by the weight on top of the container?

• The pressure that helps change the plant material into coal

• The heat that causes the sand to melt and turn into oil

• The time it takes for the plant material to decompose into gas

• The movement of fossil fuels into underground reservoirs

A student is investigating the formation of fossil fuels. She simulates the accumulation of organic material, burial under sediment, and exposure to heat and pressure over time. At which stage in her experiment are fossil fuels most likely to form?

• Immediately after the organic material accumulates

• Right after burial under sediment

• After prolonged exposure to heat and pressure

• Before any processes begin

Based on the timeline, which statements describe what likely happened to the dead plants over millions of years? Select TWO correct answers.

• The plants were quickly buried by a thin layer of soil.

• The weight of layers above created pressure on the plant remains.

• Heat from the Sun dried out the buried plants and turned them into coal.

• Pressure from the layers above caused the plants to change.

• Decomposition occurred quickly due to the presence of air in the rock layers.

A student builds a model by filling a clear container with alternating layers of organic matter and sediment. The student wants to modify the model to simulate the natural processes that lead to the formation of fossil fuels. Which modifications should the student make to the model to more accurately represent fossil fuel formation? Select TWO correct answers.

• Submerge the container in water to represent oceanic conditions.

• Place a heavy weight on the top layer of organic matter and sediment to simulate pressure.

• Illuminate the container with bright light to represent sunlight.

• Heat the container gently to simulate geothermal heat.

• Shake the container vigorously to represent tectonic activity.

A student is creating a model that demonstrates how the formation of sedimentary rocks contributes to the formation of fossil fuels. What phase in the formation of sedimentary rocks is most critical for trapping the organic matter that can eventually become fossil fuels?

• Weathering of rock into small sediment particles

• Deposition of layers of sediment on top of organic matter

• Compaction of sediment layers by the weight of overlying rock

• Cementation of sediment grains to form solid sedimentary rock
