Chemistry Limestone Quiz

15 Questions

Quiz Description

These questions are provided to you by gcequiz.com basically covers everything in the chemistry of limestone for the gcse students, with 15 questions each having four options of which one is the correct answer. 

As we all probably know, limestone is simply carbonate sedimentary rocks, an abundant rock which has so many uses. It is made up of skeletal fragments of organisms that live in water. Organisms such as foraminifera, coral and molluscs. There are different types of limestones, we have as examples; chalk, coquina, travertine, tufa etc.

Apart from chemistry quizzes for the gcse level, gcequiz.com has brought together quizzes for other levels such as ks1, ks2, ks2, gce o level, gce A level and so many others.
