Crust 1%, Mantle 84%, Core 15%
Explanation
The interior of the Earth is divided into three concentric layers based on chemical composition and physical characteristics: the Crust, the Mantle, and the Core. These layers vary significantly in thickness, density, and volume.
Volume Composition Analysis:
- Crust: This is the outermost and thinnest layer of the Earth. It constitutes only about 1% of the Earth's total volume.
- Mantle: Extending from the base of the crust (Moho discontinuity) to a depth of 2,900 km, the mantle is the most voluminous layer. It accounts for approximately 84% of the Earth's volume.
- Core: The innermost layer, extending from 2,900 km to the center of the Earth (6,370 km), makes up the remaining 15% of the volume.
Key Takeaway:
In terms of volume, the Mantle is the largest layer (84%), followed by the Core (15%), with the Crust being the smallest (1%).
