Beneath our feet lies a fascinating world of hidden layers that make up the structure of the Earth. From the solid crust we walk on, down to the molten outer core and the dense inner core, each layer plays a vital role in Earth's geological behavior. The mantle, rich in silicate minerals, drives plate tectonics through convection currents, while the outer core generates Earth's magnetic field. Understanding Earth’s structure helps scientists explain natural phenomena like earthquakes, volcanic e

LAYERS OF THE EARTH The Earth is made up of several distinct layers, each with unique composition, properties, and functions. These layers can be classified into chemical layers (based on composition) and physical layers (based on mechanical properties). 1. CRUST Definition: The outermost solid layer of the Earth where we live. Types: Continental Crust – Thick (30–70 km), less dense, mainly granite rocks. Oceanic Crust – Thin (5–10 km), denser, mainly basalt rocks. Characteristics: Relatively co
