Explanation / Answer

answer 1 - sand

detrital rocks are one kind of sedimentary rocks which are formed by the physical or mechanical processes like erosion, transportation and deposition of the protolith rocks like igneous and metamorphic rocks.

non detrital rocks are those which are formed by the chemical reactions on preexisting rocks

answer 2 - shale
