This quiz will put your geology knowledge on a tough test! There are different types of rocks in existence on the earth’s surface. Getting to understand rocks helps to mitigate and warn us about the occurrence of specific natural hazards and educates people when it comes to climate change discussions. The quiz below is designed to test your Geology knowledge. Do give it a try and see just how much you recall.
