As the earth formed, the heavier, more dense elements sunk toward the center, while the lighter, less dense ones stayed near the surface. The result was layers of rocks of similar density.
Rock density has no direct affect on war.
Rock & metal
The Earth's layers contribute to the planet's physical characteristics by the types of rocks these layers produce. The rock formation of the Earth's surface define the physical characteristics of the planet.
volcano
It is found in earth's rock layers
The formations that are sandwiched between layers of existing rock formations called sills. Another formation between layers is called laccoliths.
Earths hot interior
A laccolith is an igneous formation between two sedimentary layers
Hot, slowly flowing rock comprises the asthenosphere, which is part of the mantle.
it is a sloping layer of permeable rock sandwiched between two layers of impermeable rock and exposed at the surface.
Slate is a metamorphic rock that breaks into flat, thin layers. These layers are a result of the alignment of minerals during the rock's formation under heat and pressure, making slate ideal for use in roofing and flooring.
The bottom part of a folded rock formation is called the "axial plane". This is where the layers of rock are bent or folded due to tectonic forces.
