We saw when we studied weathering that physical weathering makes little pieces from big, and that chemical weathering dissolves some things and makes other chunks. The different chemicals went into different places, dissolved or in chunks. When geologists classify sedimentary rocks, the first divisions are based on:

Based on how the rock is formed

Explanation:

Sedimentary rocks are often classified broadly into two distinct groups depending on how the rock is formed. This two groups includes-

Clastic sedimentary rock - These are formed from the accumulation and lithification of the smaller broken fragments of rocks.

Chemical sedimentary rock - These are formed from the precipitation and consolidation of minerals and sediments that are found to be dissolved in water.

This is how the sedimentary rocks are formed and geologists are able to classify them.
