How Much Do You Know About Earth Layers And Density?
Earth's interior and the atmosphere are layered by density, consisting of a solid metal inner core, the mantle of intermediate density, and the least dense layer is the lithosphere. This quiz has been designed to test your knowledge about the different layers and density of the earth. Go through all the questions and choose a suitable answer. Let's play the quiz. All the best!
