The first step that creates sedimentary pits is when tectonic forces push rock formations upward to produce mountains. Since this rock formation is know exposed to the surface conditions, it becomes erode and weathered. These effects cause the rock to wear shovel in. Due to deposition, sorting of divers(a) fragments occurs. Think of a well out that flows down a mountain. Within this rain buckets there atomic number 18 many different materials that travel due to the velocity of the stream. Depending on how much distance is traveled by the river in a specific time defines its velocity.V=(change in distance)/(change in time)If the velocity is spry enough, it is able to budge big rocks as well as dinky rocks down the terrain. Eventually the slope becomes less and less steep, which causes the velocity of the stream to decrease. Since the velocity of the stream becomes slower as it arrives to a flat surface, it is non able to sustain a fast enough of a hurry to make the heavie r materials to continue with the journey. Usually at the bottom of this river, it will drop into a big body of water like the ocean.The different fragments are all submerged, yet divide into different groups. The reason for this is that there is lock a river velocity that causes movement in the various fragments farther down the ocean floor. This might look years later once the river has dehydrated out. Notice the big rocks are protruding from the water. This is either from corrosion to the rock formation next to the ocean or it is due to the rocks that came from a high-pitched velocity mountain stream.After all of these fragments arrange in their groups,lithification occurs. Lithification is the renewing ofunconsolidated sediments into sedimentary rock bycompaction and cementation(1).This compaction and cementation yields thesesedimentary rocks-Gravel turns into conglomerate-Sand turns into sandstone-Clay turns into shale-Shells turn into limestone e
