Question

Quizplus · Accepted Answer

The correct order of Earth's layers, from the center outward, is a solid metallic inner core, a molten metal outer core, a silicate mantle, and a silicate crust. This is based on seismic observations and studies of Earth's magnetic field. The solid inner core is believed to be made primarily of iron and nickel, while the outer core is thought to be liquid iron and nickel. The mantle is composed of solid silicate rocks, and the crust is the thin, outermost layer of the Earth's surface that supports all life. This is the correct order based on our current understanding of the Earth's structure. The inner core is thought to be solid due to the high pressure, despite the high temperature. The outer core is believed to be molten due to the lower pressure. The mantle is composed of silicates and is mostly solid, but with some pockets of molten rock. The crust is the outermost layer and is composed of solid silicates.
