List two major characteristics of sedimentary rocks.

1. Sedimentary rocks are formed through the accumulation and cementation of sediments, such as sand, silt, and clay, which are deposited by water, wind, or ice.

2. Sedimentary rocks often contain fossils, as they are formed in layers over time and can preserve the remains of plants and animals that were buried in the sediments.

1. Stratification: Sediments are deposited in layers, and these layers can be seen in the rock.
2. Fossils: Sediments can contain fossils, which are the preserved remains or traces of organisms that lived in the past.
