Sedimentary Rocks and Fossil Fuels

Front

What is sediment?

Back

Sediment is small pieces of rock, minerals, and organic material that are carried by wind, water, or ice.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form from the accumulation and compaction of sediments over time.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of sediments from one location to another, often caused by water, wind, or ice.

Front

What are fossil fuels?

Back

Fossil fuels are natural resources like coal, oil, and natural gas formed from the remains of ancient plants and animals.

Front

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume.

Front

What is cementation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together to form rock.

Front

What role do plants and animals play in the formation of fossil fuels?

Back

Plants and animals that die and are buried under layers of sediment can transform into fossil fuels over millions of years.

Front

What is the significance of the striped pattern in sedimentary rocks?

Back

The striped pattern indicates that the rocks formed in layers over time, showing the history of sediment deposition.

Front

How does pressure contribute to the formation of sedimentary rock?

Back

Pressure from overlying sediments forces the layers together, helping to form solid rock.
