Inside earth a n forms due to the diffrent temperatures of the core?

Convection cells

Explanation:

The core of the earth is the hot and very dense center of the planet that is known to be the powerhouse of the planet geothermal energy a the core has a radius of about 3,485 km from the earth crust. Planet origin is older than its core and as earlier, it was not a uniform ball of hot rocks as the violent radioactive decay and the heat that was created due to the collision of the matter form the space got accumulated about 500 million years ago. As the temperature melted as the melting upon tikf the iron and the heat began to accumulate around 1,538°C. what is also known as the earth's iron catastrophe created rapid movements in the molten rocks from the above and this resulted in the drops of the iron and metal compound and Due to this the geothermal gradient of the earth and the alongside rotation thus creates a convective cell and leads in the formation of the convection current that radiates out from this zone to the outer zones of the crust.
