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.

i think its the first one

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
