Rock layers are formed by sedimentation. Existing rocks weather and erode, are deposited, covered with additional sediments, compacted and cemented together by the precipitation of minerals from the fluids between the particles. There are other instances where layers can be created, such as repeated volcanic eruptions, but the bulk of rock layers are sedimentary in origin.
Yes, sedimentary rocks are being formed right now. Sediment is continually being deposited by erosion and transported by wind, water, and ice. Over time, these sediments are compacted and cemented together to form new layers of sedimentary rock.

Sedimentary
Clastic or bioclastic sedimentary rock is formed in this manner.
Sedimentary rocks are made by the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together.
Rocks made from sediments being compacted & cemented together.
Sedimentary rock is formed from sediments are piled on top of one another, then compacted and cemented into rocks. Sandstone and limestone are examples of sedimentary rocks.
Sandstone
Sedimentary rock is formed from the processes of compaction and cementation of sediments.
Clastic sedimentary rocks. Clastic sedimentary rocks are formed when small sediment particles are compacted and cemented together. This happens when the sediments are glued together by tiny crystals or chemicals from fluids that have precipitated in the pores between the sediments.
A rock formed as pieces older rock and sediment get pressed or cemented together.
Clastic sedimentary rocks are formed from particles of pre-existing sedimentary, metamorphic, or igneous rock that are deposited, compacted, and cemented together by natural processes.Clastic sedimentary rock is made of fragments of rocks cemented together by a mineral such as calcite or quartz.
They are called sedimentary rocks. Sedimentary rock can't be dated using radioactive dating because it is composed of sediment, which is actually small pieces of different rocks. To date it, you have to use radioactive dating on the surrounding rocks.
...sedimentary rock is formed. OR ...strata is formed. Try either.
