Which Layer Has High Density?
The Earth's inner core has the highest density. This is significantly denser than the mantle, crust, and other layers.
The Earth is composed of several layers, each with distinct properties:
- Inner Core: The densest layer, composed primarily of iron and nickel, with a density of approximately 13 grams per cubic centimeter. Its high density is due to the immense pressure at the Earth's center. [Source: homework.study.com]
- Outer Core: Primarily iron and nickel, less dense than the inner core due to the lower pressure.
- Mantle: Intermediate density, composed of silicate rocks.
- Crust: The least dense layer, consisting of lighter silicate rocks. The continental crust is less dense than the oceanic crust. [Source: homework.study.com]
The density differences between these layers are responsible for the planet's layered structure. Higher-density materials sink towards the center, while lower-density materials rise to the surface.
High Density in Other Contexts
The term "high density" is also used in other fields:
