Does the fomation of rivers vary depending on the type of rock they are constructed over Eg radiolarian the oceanic series sedimentary rock conglomerate?

Yes, the formation of the rivers vary depending with the type of rock that they are constructed over.

What is a sedimentary rock that is sometimes formed from sand deposits which consists of sand and gravel?
Conglomerate or breccia depending on the shape of the gravel.
What sedimentary clastic rock has different sized rock fragments?
Could be conglomerate or breccia, depending on whether or not the clasts are rounded or angular.
What are rocks made up of pebbles cemented together with other sediment called?
The process is called 'lithification'. ----------------------------------------------------------- Another word you could use is 'diagenesis' which is any chemical, physical, or biological change undergone by a sediment after its initial deposition and during and after its lithification. ----------------------------------------------------------- The combined process of, accumulation, stratification, sedimentation, compaction, cementation, and lithification, of deposited materials and detritus to form sedimentary rocks is called diagenesis.
Is limestone and conglomerate the same and the mohs scale number?
Limestone is is a chemically altered sedimentary rock, mostly consisting of calcium carbonate in various forms. The hardness of calcite, a common ingredient, is about 3 on the Mohs scale. A conglomerate often consists of mechanically altered sedimentary rock that has been ground into relatively small pieces while being transported and deposited as sediment by glaciers. Its Mohs hardness varies, depending on the composition of the rock which is mostly a mixture of silicates, calcite, and iron compounds.
What is the particle size of clastic sedimentary rocks?
Shale is composed of the smallest particles of other rocks.
Sedimentary rocks formed from broken fragments of other rocks are?
These are known as clastic or detrital sedimentary rocks. Depending on the size of the clasts they may be claystones (< 4 micro m), siltstones (grain size between 4 and 64 micro m) or sandstones (grain size between 64 micro m and 2 mm). If formed of angular fragments larger than 2mm in a finer grained matrix, this type of rock is known as a breccia. If the fragments are rounded, and larger than 2mm then it is a conglomerate.
How could you explain the presence of an igneous rock in a bed of sediments rock?
The sediment from which sedimentary rock is formed originally came from other rocks that weathered away. In some sedimentary rocks, especially breccia and conglomerate, some of those rock fragments can still be identified. If it does not appear to be part of the sediment, there are a few possible explanations depending on their relationship. If there is a layer of igneous rock between sedimentary layers then it could be from a volcanic eruption that occurred during the time of sedimentation, or a sill that intruded between layers after they formed. If the igneous rock appears to cut through the sedimentary rock then it most likely is an intrusion. If there is a piece of igneous rock that happens to be in an area where the local bedrock is sedimentary then it may have been transported there by glaciers.
Is sandstone a common sedimentary rock?
Depending on where you live, yes.Read more, below.
Is sandstone igneous or sedimentary or metamorphic?
Sandstone is a sedimentary rock which is made up of sand grains which have been compressed to form a rock that has very weak bonds holding the grains together. The grains themselves can be igneous, sedimentary or metamorphic depending on which rock the grains were eroded from.
What minerals are in conglomerate?
Practically anything can be in conglomerate. Conglomerates that might be forming today could even contain metals like steel, aluminum, gold jewelry or plastics and other synthetic materials; of course these conglomerates will not become solid rock for millions of years.
How can a sedimentary rock be converted to an igneous rock?
the already formed sedimentary rock can be melted down under magma depending on what the type of rock is and then reformed as a igneous rock
What type of rock might gravel become if subjected to deep burial for millions of years?
Conglomerate or breccia, depending on the shape of the composite clasts.
