Write the Layers of the Earth
The Earth is composed of several distinct layers, each with unique characteristics and compositions. Starting from the outermost layer, we have the crust, which is the thin, solid outer shell where we live. It includes both the continental crust, which forms the continents, and the oceanic crust beneath the oceans. Beneath the crust lies the mantle, a thick layer of semi-solid rock that extends to a depth of about 2,900 kilometers. The mantle is divided into the upper and lower mantle, with the upper section being more pliable and capable of flowing slowly.
Below the mantle is the outer core, a layer of liquid iron and nickel that surrounds the inner core. The movement of molten metals in this layer generates Earth’s magnetic field. Finally, at the center of the Earth is the inner core, a solid sphere composed primarily of iron and nickel. Despite its high temperature, the immense pressure at this depth prevents it from melting. These layers together make up the complex structure of our planet, influencing everything from plate tectonics to magnetic fields.
