5.7A STAAR Review Sedimentary Rock and Fossil Fuel Formation

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock that is formed by the accumulation and compaction of mineral and organic particles, often in layers.

Front

How do fossil fuels form?

Back

Fossil fuels form from the remains of dead plants and animals that are buried under layers of sediment for millions of years, where heat and pressure transform them.

Front

What is coal?

Back

Coal is a solid fossil fuel that forms underground from decayed plant material due to heat and pressure over millions of years.

Front

What are non-renewable resources?

Back

Non-renewable resources are natural resources that cannot be quickly remade or replaced, taking millions of years to form.

Front

Where is natural gas formed?

Back

Natural gas is formed at the bottom of oceans from the remains of marine organisms that are buried and subjected to heat and pressure.

Front

What is the primary source of coal?

Back

The primary source of coal is decayed plant material, primarily from ancient forests.

Front

What role do decomposers play in the formation of fossil fuels?

Back

Decomposers break down dead plants and animals, but for fossil fuels, the remains must be buried and undergo heat and pressure instead of being fully decomposed.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished quickly, while non-renewable resources take millions of years to form and cannot be replaced in a human timeframe.

Front

What is the process of compaction?

Back

Compaction is the process by which sediments are pressed together under pressure, leading to the formation of sedimentary rock.

Front

What is the significance of sediment in fossil fuel formation?

Back

Sediment helps to bury the remains of plants and animals, providing the necessary pressure and heat for fossil fuel formation.
