The upper mantle is composed of peridotite, which is rich in olivine, iron, magnesium, and silicates. This layer lies between the crust and the lower mantle at a depth of about 410-660 kilometers. The inner core is composed of solid iron and nickel, while the outer core is composed of liquid iron and nickel. The crust is the outermost layer of the Earth, and the asthenosphere is a part of the upper mantle where the solid rock is weak and can flow like a fluid.
