what are the four parts of the mantle from top to bottom?

The mantle is divided into several layers: the upper mantle, the transition zone, the lower mantle, and D” (D double-prime), the strange region where the mantle meets the outer core. The upper mantle extends from the crust to a depth of about 410 kilometers (255 miles).

The layers of Earth are: Crust - 5 to 70 km thick. Mantle - 2,900 km thick. Outer Core - 2,200 km thick.

Broadly speaking, the Earth has four layers: the solid crust on the outside, the mantle and the core -- split between the outer core and the inner core. Broadly speaking, the Earth has four layers: the solid crust on the outside, the mantle and the core — split between the outer core and the inner core.

The Mantles There are very small differences between the two layers. The upper mantle has Olivine (a very special rock), compounds with silicon dioxide, and a substance called Peridotite. The lower mantle is more solid than the upper mantle.

The three main layers of Earth include the crust (1 percent of Earth's volume), the mantle (84 percent), and the core (inner and outer combined, 15 percent).

The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.

A cut-away of Earth's layers reveals how thin the crust is when compared to the lower layers. Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust.

The Earth is divided into three chemical layers: the Core [Inner Core (D) and Outer Core (C)], the Mantle (B) and the Crust (A). The Core is predominantly composed of iron and nickel. Even after 4.5 billion years of cooling, the Earth's core remains very hot.

The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
