What is erosion and how does it relate to sedimentary rock formation?

Back

Erosion is the process of transporting weathered rock particles by wind, water, or ice, which contributes to the formation of sedimentary rock.

Explain the term deposition in the rock cycle.

Back

Deposition is the process where sediments settle out of the transporting medium (like water or wind) and accumulate in layers.

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing the space between them.

What role does cementation play in the formation of sedimentary rocks?

Back

Cementation is the process where dissolved minerals precipitate from water and fill the spaces between sediment particles, binding them together.
