Explanation:

• Just like an onion, Earth is made up of several concentric layers with one inside another. Earth’s uppermost layer is the crust, which is the thinnest of all the layers. On the continental masses, it is about 35 km and on the ocean floors only 5km.
• Silica and alumina are the main minerals that constitute the continental mass, and are called sial (si, silica; al, alumina). Silica and magnesium are the main minerals that constitute the oceanic crust, and are called sima (si, silica; ma, magnesium).
• Continental crust is less denser than ocean crust as the latter is made of basaltic rocks.
• Core constitutes the innermost layer. Its radius is about 3500 km. Nickel and iron constitute the core, and it is called nife (ni, nickel; fe, ferrous, i.e. iron). The temperature and pressure at the central core are very high. It is the molten iron in core which gave rise to magnetic field of Earth.
