Join environmental engineer Will Toliopoulos as he takes us into the field to explore the rock cycle. We begin with a tour of Earth's core, mantle and crust, and how they interact to form the three main types of rock - igneous, sedimentary, and metamorphic. Next is a detailed exploration of the three rock types, how they are formed, their properties, structure and characteristics. And finally there is the rock cycle itself, here explained in detail using real-life examples and dynamic graphics. Our youthful presenter clearly explains concepts and defines key terms while keeping this complex topic fresh and interesting.
