Question

Put the following steps in sequence to describe how chemical sedimentary rocks form ?

1. When a body of water becomes saturated with dissolved minerals,crystal precipitate out of solution

2) they settle to the bottom , creating layers of sedimentary rock

3) during chemical weathering , minerals can be dissolved and carried into lakes and ocean

Answer 1

Answer: Option (D)

Explanation: Chemical weathering refers to the breakdown of minerals and forming new minerals due to the presence of chemical elements. For example, hydrolysis.

Due to the chemical weathering, initially, the minerals will get dissolved and are carried to the streams and oceans. After that, due to the saturation by water, the crystals will be precipitated out of that existing solution.

This crystals then sinks down to the bottom, forming sedimentary rocks.

Thus, the correct answer is option (D).
