Geology- Earth And Rocks Quiz

There are different types of rocks on the Earth’s surface, and each has its distinct characteristics. Back in school, we learned more about rocks, how they are formed, and their benefit to the Earth’s surface. Just how attentive were you? Take up the test below, and let’s get an idea of what you remember on the rocks and rock cycle topics.
