1. The Crust--The outer skin of the planet is composed of igneous, metamorphic, and sedimentary rock.
2. The Mantle--The layer directly below the crust which is delineated from the crust by the Mohorovicic Discontinuity, where seismic waves increase in velocity. The division between the mantle and the crust is a chemical one, the rocks and constituent minerals being higher in magnesium and lower in silicon and aluminum than crustal rocks. The mantle comprises 84% of Earth's volume.
3. The Outer Core--The outer core lies at a depth from 2900 km to 5150 km. It's composed of liquid iron and nickel along with small amounts of lighter elements, with temperatures ranging from 4,000 degrees C to 6,100 degrees C near the boundary with the inner core.
4. The Inner Core--From the boundary with the outer core to the center of the Earth, a distance of about 1220 km is the solid sphere of the inner core, a ball of incredibly hot iron-nickel alloy. Temperatures here reach between 5,000 and 7,000 degrees C, and pressures are calculated to be around 3,000,000 units of atmospheric pressure. Despite the high temperature, at these pressures the metals cannot remain molten.

∙ 9y agoThe layers of the earth are the crust, the mantle, the outer core and the inner core. The crust and mantle are composed of various types of rock, the outer core is composed of liquid iron and nickel, and the inner core is a ball of incredibly hot iron-nickel alloy.

What characteristics was first used to identify earths layers?
the berrics
How do earths layers contribute to the planets physical characteristics?
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.
What made the Earths layers?

How many layers in earths mantle?
there are 7 layers in earths mantle.
What are the pauses in Earth's atmosphere?
Atmospheric pauses are the dynamic boundaries between each of the earths atmospheric layers. Each pause contains characteristics of both layers in varying concentrations.
