Study Notes
Earth's Layers and Their States of Matter
- The crust is the outermost layer of the Earth, comprised of solid material.
- The crust is divided into large segments known as tectonic plates, which float on the underlying mantle due to convection currents.
- The mantle lies beneath the crust and is characterized by its semisolid state, consisting of molten rock that flows slowly over geological time scales.
- The outer core is a layer of liquid metal, primarily composed of iron and nickel, which generates Earth's magnetic field through its movement.
- The inner core is located at the center of the Earth and is solid due to immense pressure, despite the high temperatures present.
- Understanding the composition and state of each layer is essential for studying geological processes and phenomena such as tectonics and magnetism.
