The Earth's mantle is the heaviest layer.
The Earth's Layers and Their Weight
The Earth is composed of several layers, each with distinct characteristics and densities. The mantle, as described in the provided reference, is the largest layer, extending 1800 miles thick. It's made up of extremely hot, dense rock, which even flows under pressure due to substantial temperature variations. This makes it significantly heavier than the crust or the core, considering its massive volume and dense composition.
While other references discuss "layers" in different contexts (like Photoshop layers, Beyblade layers, or layers in fabrics and quilting), the question is most accurately interpreted as referring to the Earth's geological layers. In this context, the answer remains the same:
- The Mantle: The earth's mantle is the heaviest layer due to its immense size and density.
