Sedimentary rocks record; 1. Time (Age) of formation. 2. Environment of formation.
Sedimentary rocks can be formed at any temperature found on the surface of the Earth. Diagensis of sedimentary rocks occurs at temperatures up to the formation of chlorite (200C) from then on they are metamorphic rocks.
Sedimentary rock formation begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth's surface they begin the long slow but relentless process of becoming sedimentary rock.
Sedimentary rocks form the same as they did in the past.
Sedimentary Rocks. Sedimentary rocks are created from stratification by the layering of materials on one another which then get compacted and cemented by sedimentation process over long period of time. The whole process of formation of sedimentary rocks from sediment is called Diagnesis. Examples of sedimentary rocks are limestone, chalk, and sandstone.

Although sedimentary rocks form in a variety of processes, the first process that would occur in the formation of the most common sedimentary rocks would be that of weathering, which is the breakdown of rocks into smaller pieces through chemical or mechanical means by nature.
Cementation
Sedimentary rocks that are made from compressed plants are called biologic sedimentary rocks. Accumulated carbon-rich plant material can result to the formation of coal.
Sedimentary rocks can be formed at any temperature found on the surface of the Earth. Diagensis of sedimentary rocks occurs at temperatures up to the formation of chlorite (200C) from then on they are metamorphic rocks.
Cementing is not a process involved in the formation of sedimentary rock.
SEDIMENTARY ROCK FORMATION, begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth's surface they begin the long but relentless process of becoming sedimentary rock.
lithification (cementing, compacting, and hardening)
Weathering
The three kinds of rocks by their method of formation are IGNEOUS rocks, SEDIMENTARY rocks and METAMORPHIC rocks. Igneous rocks cool from magma or lava. Sedimentary rocks form by the deposition of particulates and silt. Metamorphic rocks form from rocks (usually sedimentary) that are compressed and heated underground.
