What is sediment?

Back

Sediment refers to small pieces of material, such as sand, pebbles, and clay, that are transported and deposited by wind, water, or ice.

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks into smaller pieces due to natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which sediments are moved from one location to another, often by water, wind, or ice.

Front

What is compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and leading to the formation of sedimentary rocks.

Front

What are the layers of sedimentary rock called?

Back

The layers of sedimentary rock are called strata.

Front

What is the Law of Superposition?

Back

The Law of Superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest layers are at the top.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient living organisms found in sedimentary rocks.

Front

What is lithification?

Back

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

Front

What is cementation?

Back

Cementation is the process where minerals fill the spaces between sediment particles and bind them together to form rock.
