what is the difference between the earth's inner and outer core?

At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles (about 1,220 km), according to NASA. It is surrounded by a liquid, outer core composed of a nickel-iron alloy. The outer core is about 1,355 miles (2,180 km) thick.

Every inner planet has a core. ... Mars's core is made of liquid iron sulfide mixed with some nickel. Inner and Outer Cores. Earth and Venus have an inner core and an outer core; the inner core is solid due to the trememdous weight of the matter above it, and the outer core is liquid.

The core consists of extremely hot metal layers instead of rock. Iron and nickel make up the outer section of the core, while the interior is almost entirely iron. ... The core is much denser and heavier than the mantle. The core also creates heat, while the mantle just absorbs it.

Although the core and mantle are about equal in thickness, the core actually forms only 15 percent of the Earth's volume, whereas the mantle occupies 84 percent. The crust makes up the remaining 1 percent.
1037917
The crust and the inner core are solid, whereas the outer core and inner mantle are liquid.

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.

Earth has four different layers: the inner core, the outer core, the mantle, and the crust.

Even though it is hotter than the surface of the Sun, the crystallized iron core of the Earth remains solid. ... Spinning within Earth's molten core is a crystal ball – actually a mass formation of almost pure crystallized iron – nearly the size of the moon.

Inside the Earth The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter.

Earth is composed of multiple layers, which can be defined either by composition or by mechanical properties. The crust, mantle, and core are defined by differences in composition. The lithosphere, asthenosphere, mesosphere, and outer and inner cores are defined by differences in mechanical properties.

The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth's interior is generally divided into three major layers: the crust, the mantle, and the core.

Earth's internal layering can be defined by this resulting chemical composition. 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).

They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core. Let's take a look at them and see what they have going on. Like all terrestrial planets, the Earth's interior is differentiated.

The Earth consists of three layers: the crust, the mantle and the core. The core, the innermost layer, is rich in iron and very dense. It can be further subdivided into the inner and outer core. The mantle is the intermediate layer of the Earth and can be subdivided into the inner and outer mantle.

The Earth consists of three layers: the crust, the mantle and the core. The core, the innermost layer, is rich in iron and very dense. ... Most of the mantle is a thick fluid that moves in currents, but the very outermost portion of the outer mantle is solid. This portion and the solid crust make up the lithosphere.

These layers are both physically and chemically different. The Earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid center called the inner core. ... The crust is the outermost layer of the Earth.
