A sedimentary rock composed of silt-sized particles, larger than clay but smaller than sandstone.

Front

What are the main components of sedimentary rocks?

Back

Sedimentary rocks are primarily composed of minerals, organic materials, and sediments.

Front

How is sedimentary rock formed?

Back

Sedimentary rock is formed through the accumulation and compaction of sediments over time.

Front

What is the difference between sandstone and siltstone?

Back

Sandstone is composed of sand-sized particles, while siltstone is made up of silt-sized particles.

Front

What is the significance of fossils in sedimentary rocks?

Back

Fossils provide evidence of past life and can help in dating the rock layers.

Front

What is the process of lithification?

Back

Lithification is the process of turning sediments into solid rock through compaction and cementation.
