Layers of Earth

The outer core, composed of liquid iron and nickel, creates Earth's magnetic field through the movement of molten metal.

The asthenosphere is a semi-solid layer of the upper mantle that allows tectonic plates to move due to its plastic-like properties.

The lithosphere is the rigid outer shell of the Earth, divided into tectonic plates that float on the asthenosphere.

Oceanic crust is denser than continental crust because it is made of basaltic rocks, while continental crust is mainly granitic.

The core is mainly composed of iron and nickel, with the inner core being solid and the outer core being liquid.

The inner core's temperature is estimated to be around 6,000°C, similar to the surface of the Sun.

Convection currents in the mantle move heat and material, driving the motion of tectonic plates.

The Earth's crust is rich in silicon and oxygen, forming silicate minerals such as quartz and feldspar.

The oceanic crust is mainly composed of Silica and Magnesium, therefore it is called "Sima" - where "Si" stands for Silica and "Ma" stands for Magnesium.

The Mohorovicic Discontinuity (Moho) marks the transition between the Earth's crust and the mantle.
