Have you ever wondered what lies deep beneath the surface of our planet? The ground we walk on is just the beginning of a complex and dynamic world. This course provides a clear, foundational journey into the Earth's interior, helping you understand the composition, properties, and interactions of each geological layer. You will gain a solid grasp of the science that explains our planet's structure. What you'll learn: - Understand the key characteristics of the Earth's crust, mantle, and core. - Differentiate between the properties of continental and oceanic crust. - Learn how the lithosphere and asthenosphere drive plate tectonics. - Explore the function of the outer and inner core and their effect on the magnetic field. - Grasp the basic principles of how seismic waves reveal the planet's interior. - Connect geological layers to real-world phenomena like volcanoes and earthquakes. The course starts with essential terminology and principles, then systematically guides you through each layer, building your knowledge from the surface inward. This course is designed for absolute beginners. No prior knowledge of geology or earth science is required to get started. Enroll to build your foundational understanding of the planet we call home.
