Inside earth a form due to the different temperature of the core and mantle?

Inside the Earth, the core and mantle have significantly different temperatures, which create distinct physical properties and behaviors. The core, primarily composed of iron and nickel, is extremely hot, with temperatures reaching up to 5,700 degrees Celsius (10,300 degrees Fahrenheit). This heat drives convection currents in the mantle, causing the semi-fluid rock to flow slowly. These temperature differences contribute to geological processes such as plate tectonics, volcanic activity, and the generation of Earth's magnetic field.
