Where are sedementary rocks formed?

Answer 1

Sedimentary rocks can form anywhere sediments are deposited in abundance, including seas, oceans, lakes, swamps, deltas, marshes, deserts, and also from mineral precipitation in caves, and from evaporation of bodies of water creating evaporites such as rock salt and rock gypsum.

Answer 2

Over time existing rocks are weathered and eroded; suface runoff, from the water cycle carry rock sediments to rivers, where over time, rock sediments, ie. silt, settle and accumulate on the riverbed or even the seabed. Due to chemical changes and compaction the sediments lithify, via a process called lithification, to become sedimentary rocks. Note that there are numerous sources of the carbon in rocks ie. the biological pump(dead zooplankton sinking to the ocean floor), dissolved carbon in water( the bi-product of respiration) and also limestone for example contains fossilized crinoids( marine echinoderms).

Answer 3

Land is sometimes claimed by water and the majority of the bottom of these bodies of water are covered with silt. Due to the huge amount of water sitting on top of the silt this aids in the compaction of this debris. Lastly the movement of water also bring small shells and animals that normally only move with current when dead will normally become part of this process.

Answer 4

Although there is a bit more to it, the simple answer is that sedimentary rocks form as the name suggests. Tiny bits of eroded rock wash down to a place where they can go no further. There they collect, and form sedimentary deposits. This can happen either on land, or in water. Once these deposits form, other sediment is deposited atop them. Eventually, the weight of these deposits compresses the earlier deposits until they become rock.

Answer 5

Sedimentary rocks are mainly formed on the ocean bed at the mouth of a river. The fine particles resulting from the erosion of rocks will settle on the sea bed. The coarser particles will settle closer to shore, and the finer ones further out. Determined by the settling time of the particle.

In flood conditions, some of the coarser particles will be transported further out than usual. Thus our sedimentary rock may well have coarser and finer bands.

A more or less uniformly grained rock, such as slate, will have been formed a greater distance from land.

Answer 6

Usually in basins where sediments become trapped and grow in number, or at the bottom of seas and oceans.

Answer 7

At a bottom of a lake, a river delta, an ocean, or similar location where further movement is restricted or slowed down.

Answer 8

layers of dirt and rock are presses and get compacted

Answer 9

sedimentary rocks are formed by the repeated deposition of rocks carried by the water or river.
