Learn how sedimentary rocks form through weathering, erosion, deposition, and lithification. Explore major types like sandstone, shale, and limestone, their real-world uses, fossil preservation, and role in water/energy resources. Includes practical field trip tips and comparisons to igneous/metamorphic rocks.

Clear explanation of Earth's lithosphere - its composition (crust + upper mantle), tectonic plate movement, thickness variations, and why it matters for earthquakes, volcanoes, and resources.

Discover the 4 main layers of Earth - crust, mantle, outer core, inner core. Learn their depth, temperature, composition and how they impact earthquakes, volcanoes and magnetic fields.
