This is a sedimentary rocks quiz trivia questions! Sedimentary rocks are made as a result of an accumulation of particles to form a rock. These rocks are formed as a result of different process and have different characteristics as well. In this quiz, you will get to test out the different types of sedimentary rocks, their formation as well as sizes. Give it a try and see how well you do!
