Answer:
Step-by-step explanation:
The earth is a dynamic planet and it is constantly changing. Both external and internal processes interacts.
The earth broken down into slabs/plates called lithosphere that moves on the weak asthenosphere, at margins between these plates, new materials are brought up and some are destroyed through tectonic activities. Sedimentary rocks can therefore be destroyed and transformed into other rocks at such margins.
Also, on the earth surface, external processes helps break down rocks. Some of the processes are weathering and erosion. Sedimentary rock strata observed on the earth have shown periods of non-deposition in them.
External processes and tectonic forces on the earth can considerable influence and interrupt sedimentary deposition on the crust.
