Question

Deposition takes place in which conditions?

(a) Ordinary pressure and temperature

(b) High temperature and low pressure

(c) High pressure and low temperature

(d) High pressure and high temperature

This question was posed to me in an internship interview.

My enquiry is from Sedimentary Rocks and Their Mode of Formation in chapter The Study of Rocks of Engineering Geology

Answer 1

The correct answer is (a) Ordinary pressure and temperature

To elaborate: The sorting or grading occurs during the deposition stage of the formation of sedimentary rocks and the deposition happens in layers in most cases. Deposition generally takes place under ordinary pressure and temperature conditions.
