Gravity !... Gravity draws everything towards the centre of the Earth - therefore the heaviest materials are closer to the core.
The layer of the Earth that contains dense materials like iron and nickel is the core. It is divided into two parts: the outer core, which is liquid, and the inner core, which is solid. These materials play a key role in generating Earth's magnetic field.
The least dense layer of the earth is the Crust , the mantle is second densest , whereas the core is the most dense layer of the earth
It is neither. The densest layer is the inner core. The least dense layer is the crust.
The crust is the least dense portion of the solid Earth because it is the thinnest layer.
The core is the most dense layer
The troposphere is the closest to the Earth and most dense atmospheric layer
The least dense layer will be found on top of the other layers, as less dense materials tend to float on top of denser materials.
No, the mantle is not the bottom layer of the Earth. The mantle is located between the Earth's crust and core, making up a significant portion of the Earth's volume. The core is the deepest layer, found at the center of the Earth.
The Earth's Crust.
i think the crust
The Earth's crust is made up of low-density materials such as oxygen, silicon, and aluminum. This layer is divided into two parts: the continental crust, which is thicker and less dense than the oceanic crust.
The least dense layer of the Earth is the crust, particularly the continental crust, which is primarily composed of lighter materials such as silicate minerals. This can be inferred from seismic studies and geological surveys that indicate the composition and density variations of Earth's layers. Additionally, the crust's buoyancy allows it to "float" on the denser mantle beneath, much like how less dense objects float on more dense liquids.
