why do sedimentary rocks frequently show stratification(layering of sediments)?

Question

science homework, pleas help!

help please

Answer 1

Sedimentary rocks are formed through a special sequence of events. the products of weathering are the typical materials from which sedimentary rocks are made, that is ions in solution, clay minerals and resistant minerals or unweathered fragments. These materials are eroded, transported, and sedimented. They are transported by mainly by rivers, but also by the wind, waves, currents, glaciers, gravity (mudflows, landslides), etc. Then they are compacted, dehydrated and often cemented.
Sedimentary rocks make up about 75% of the surface of the continents even though they make up only a small part of the continental crust. Many times in the past the continents have been covered by shallow, warm seas which deposited thick sequences of sediments.
The environment of sedimentation can usually be determined. Sediments are deposited in a variety of depositional environments such as river channels, flood plains, deltas, sand dunes & alluvial fans as well as lakes, swamps and estuaries. Marine environments include beaches, shallow marine, deep marine, reefs, bays

Answer 2

Stratification Of Sediments And Rocks

Answer 3

simply because it was formed this way lay by another actaly sedimentary rocks are group of layers that was formed by time and the first layer is the oldest and the out side layer is the newest.

Answer 4

The stratification is due to either geological structure or changes in depositional environment of the rock type

Answer 5

cause that is what sedimentary rocks are

metamorphic rocks show change due to heat and pressure while igneous rocks are formed straight out of magma

Answer 6

Because sediments are laid down in layers, thus they show layering.
