what is the difference of the inner and outer core?
253017
The primary difference is that the inner core is solid due to immense pressure, while the outer core remains molten and is churned and stirred by the independently rotating inner core. This relationship gives rise to the “Geodynamo,” the source of Earth's powerful magnetic field.

Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel. The inner core is solid, while the outer core is liquid.

The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). ... However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting.

The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere. The origin of these layers and how scientists know about them is fascinating.

The outer core is 2,300 kilometers (1,429 miles) thick, while the inner core is 1,200 kilometers (746 miles) thick. The outer core is mainly composed of a nickel-iron alloy (liquid iron), while the inner core is almost entirely composed of a pure solid iron body.

Earth is divided into three layers . core, mantle and crust. These layers are further divided into two parts the inner and outer core , upper and lower mantle ,Continental and oceanic cruth. Both inner ad outer core are mostly made of mostly iron and some nickel .

Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. ... The inner core is solid, while the outer core is liquid.

As adjectives the difference between outer and outermost is that outer is outside; external while outermost is (outer).

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. ... It is made of solid rocks. It is mostly made of the lighter elements, silicon, oxygen, aluminium.

Why It Matters The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.

⭕️The innermost part or layer of the earth is known as the inner core of the earth. The layer that surrounds the inner core is known as the outer core of the earth. The outer core of the earth is located 2,890 kilometers (1,400 miles) beneath the surface of the Earth. ...

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.

Inner lid pressure cookers vs outer lid pressure cookers In the inner lid models, the top of the lid goes inside of the cooker. Whereas in the outer lid model, the top of the lid stays outside of the cooker container.

The layers of different chemical composition outward from the centre of the Earth are as follows: core, mantle, and crust. At the centre is the densest of the three layers, the core. It is mostly metallic iron with small amounts of nickel and other elements. The outer boundary of core is at a depth of 2,900 kilometres.

They both mean "inside" but they're not necessarily interchangeable. "Inner" means a thing that is within but not necessarily contained by another thing, e.g. "inner loop", "inner heart". "Internal" feels a little more technical and means "of the inside" as well as "on the inside".

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. The inner core spins at a different speed than the rest of the planet.
