» Weathering - The first step in the formation of sedimentary rocks is breaking down of solid rocks into fragments and small particles. This is called weathering. It can take place due to several factors, such as physical (e.g., physical or mechanical processes, like action of water and wind) and chemical (variation in temperature and pressure).
» Erosion - It involves the action of natural agents on soil and rocks present on the surface of the Earth and transporting the same to another location. Erosion is the transition step between weathering and transportation.
» Transportation - Carrying the broken down matter to a different locality involves transportation. The shape of rock fragments after transportation helps in analyzing the distance traveled and the environmental conditions.
» Deposition - This step follows transportation where the material or sediments get deposited after the energy of transportation drops down.
» Lithification - Lithification helps in the formation of sediments into a rock. As the layers of sediments get deposited over one another, the process of compaction starts. The overlying weight increases the pressure on the sediment layers below, thus eventually cementing them together, resulting in a sedimentary rock.

there are 3 types of sedimentary rocks: Clastic, chemical and organic. Clastic sedimentary rocks are made of others rocks compacted together. Sandstone is a good example. It is made of sand grains compacted together. Chemical sedimentary rocks are formed when water with something dissolved in it evaporates. When water evaporates, only the molecule h2O turns to gas. Anything dissolved in the water stays behind. (sugar, salt) Organic sedimentary rocks are made out of things that were once living. Coal is organic because it is made of dead leaves and plant material compacted together. At the bottom of oceans where the skeletons of microorganisms pile up, an organic sedimentary rock forms. the white cliffs of dover are a good example of and organic sedimentary rock.
Of you are looking for the answer to #12, on pg. 102-103 chpt. Review for eighth grade science (Book title: Earth science) then the answer is c. Cross-bedding
They are sandstone, limestone, chalk, and slate.
Stratification
Its a rock that is made up of many layers
A "metamorphic" rock.
Sedimentary rock is a type or classification of rock so designated by its method of formation. Minerals are inorganic naturally occurring solids, with a definite chemical composition and a crystalline structure.
Detrital sedimentary rock Chemical sedimentary rock Biological sedimentary rock
it depends of the structure and the way the rock is form
Yes it is possible for a sedimentary rock to be changed into a different sedimentary rock.
sedimentary rock has different layers called as bedding
A "metamorphic" rock.
A palaeocollapse is a rock structure resembling the karst landform, but formed essentially by the dissolution of underlying sedimentary rock.
A geode is a chemical sedimentary structure formed by mineral precipitation, similar to the way sedimentary cave structures are formed.
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................

Clastic sedimentary rock.
Detrital sedimentary rock Chemical sedimentary rock Biological sedimentary rock

horizontal bedding is sedimentary rock structure in which layers of rocks lies horizontally.
it depends of the structure and the way the rock is form
Yes it is possible for a sedimentary rock to be changed into a different sedimentary rock.
