How do clastic sedimentary rocks form

When the rocks are weathered, they are broken down into smaller particles or sediments. These sediments are then transported from one place to another by the agents such as wind, water and ice. These sediments are then deposited in a different area and over a due course of time, these sediments undergoes compaction and lithification, forming clastic sedimentary rocks. The word 'clastic' refers to the weathered and broken fragments of rock particles.

For example, Conglomerate, Sandstone and Breccia.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
