Which of the following layers of Eurth has the greatest density Crust Mantle Outer core

The layer with the greatest density is the outer core. This layer is composed mainly of liquid iron and nickel and has a density of approximately 9.9 to 12.2 grams per cubic centimeter, making it much denser than the crust and mantle, which have lower densities due to their solid rock composition. Interestingly, the flow of the liquid outer core is responsible for creating Earth’s magnetic field through the dynamo effect! This magnetic field plays a crucial role in protecting our planet from harmful solar radiation and cosmic rays, making it essential for sustaining life on Earth.
