Oceans, rivers, and other water bodies are a magnificent part of this world. Are you ready for some marine science quiz questions and answers? The study of marine life, or we can say water life, and organisms in the ocean, involves biological and physical sciences. It is said that there is so much to explore in marine life that hasn't See morebeen explored yet. Here, you will learn more about the marine world. Let's see how much you really know.
