Convection currents in the outer core are due to heat from the even hotter inner core. Above discussion clarifies that the inner core is the innermost layer of earth that is solid in nature, whereas outer core surrounds the inner core and it is a liquid layer. We don't have any banner, Flash, animation, obnoxious sound, or popup ad. Figure 1. Scientists believe the solid inner core stabilizes the magnetic field produced in the outer core. The outer core of the earth is located 2,890 kilometers (1,400 miles) beneath the surface of the Earth. INGE LEHMANN : How Inge Lehmann used Earthquakes to discover the Earthu2019s inner core. It is a widely-accepted that the inner core is gradually expanding because the liquid outer core cools down and solidifies at the place where the two layers meet. The earth’s inner core has a solid nature due to high pressure on it while the outer core of the earth is liquid in nature.

The topmost layer is crust, which is followed by the thickest layer known as the mantle. Use this resource to answer the questions that follow. The density of Earth’s surface layers is much less than the overall density of the planet, as calculated from the planet’s rotation. It has been suggested the inner core could also be a big iron crystal. Our planet is made up of four layers: the crust, mantle, outer core and inner core. Metallic meteorites are thought to be representative of the core. Both parts of the core are much hotter than the boiling point of iron, its the very high pressure down there that stops them becoming gaseous iron and nickel. The inner core is located 6,371 kilometers (3,958 miles) deep beneath the surface. The nature of the inner core of the earth is solid due to high pressure on it. The inner core is located 6,371 kilometers (3,958 miles) deep beneath the surface on the flip side, the outer core of the earth is located 2,890 kilometers (1,400 miles) beneath the surface of the Earth.


This growth is believed to be important in generating the planet’s magnetic field. The main difference between the inner core and outer core of the earth is that inner core of the earth is the innermost layer of our planet, whereas outer core is the layer that surrounds the inner core. We’d love your input. His research suggests the inner core is like a long crystal running north to south. The main difference between the inner core and outer core of the earth is that inner core of the earth is the innermost layer of our planet, whereas outer core is the layer that surrounds the inner core. Unlike the inner (or solid ) core, the outer core is liquid.
The temperature of the inner core is 5,400 degrees Celsius, on the other side, the temperature of the outer core is about 4,000 to 8,000 K (6,740 – 13,940 degrees F or 3,730-7,730 degrees C). Intense pressure present within the inner core prevents the iron from melting. Aimie Carlson is an English language enthusiast who loves writing and has a master degree in English literature. The inner core is the innermost layer of the Earth, and is believed to be a solid ball composed of iron and nickel along with some light elements (e.g., oxygen, sulfur, silicon). Seismologist Inge Lehmann was the first one who discovered the solid inner core surrounded by a liquid outer core. Scientists know that the outer core is liquid and the inner core is solid because: The heat that keeps the outer core from solidifying is produced by the breakdown of radioactive elements in the inner core. It has a radius of about 2,300 kilometers or 1,400 miles thick. Did you have an idea for improving this content?

It stretches to about 2,300 kilometers (1,400 miles). The outer core of the earth has a liquid nature. The core will not provide a firm base of contraction for the phasic muscles, which results in lost limb power, low economy of movement and susceptibility to injury. It is estimated that the temperature of the outer core is from 4,000-8,000 K (6,740-13,940 degrees F or 3,730-7,730 degrees C) as it gets near the inner core, and 3,400-4,500 K (4,940-7,640 degrees F or 2,730-4,230 degrees C) in its outer regions. The layer that surrounds the inner core is known as the outer core of the earth. Sign up for our newsletter to get comparisons delivered to your inbox. S-waves do not go through the outer core. The temperature of the inner core is estimated to be about 5,400 degrees C or 9,800 degrees F, far beyond iron’s melting point. The innermost layer is the core, and it is composed of the outer and inner core. The temperature of the outer core is 4,000 to 8,000 K (6,740-13,940 degrees F or 3,730 – 7,730 degrees C). Follow her on Twitter at @AimieCarlson. The liquid outer core is thought to create Earth's magnetic field through convection currents and the Coriolis effect. The strong magnetic field is caused by convection in the liquid outer core. This core of the earth is made up of a solid ball of iron and nickel and some light elements, e.g., oxygen, sulfur, and silicon, etc.

What materials can P-waves travel through? Scientists know that the core is metal because: If Earth’s core were not metal, the planet would not have a magnetic field. The layer of earth that surrounds the inner core of the earth is known as the outer core. Because the Earth's inner core is a solid lump of iron, you may think that it is the source of the Earth's magnetic field. In addition, scientists also believe this phenomenon indicates a homogeneous characteristic of the inner core; that is, it remains solid if it is growing into the liquid outer core. The radius of the inner core is about 1,220 kilometers or 768 miles conversely the radius of the outer core of the earth is approximately 2,300 kilometers or 1,400 miles thick. A well-conditioned inner unit depends on strong outer unit systems to protect the inner unit muscles, the spinal ligaments and joints. It was suggested in 1940 that this inner core is solid iron. The earth’s inner core is a solid ball of iron, nickel and other metals, while the outer core is liquid metal composed of iron and nickel as well. The topmost layer is crust, which is followed by the thickest layer known as the mantle. It is believed to be between 250 to 400 kilometers in diameter. We need money to operate the site, and almost all of it comes from our online advertising. Convection currents in the outer core are due to heat from the even hotter inner core. The outer core is believed to be about 2,300 kilometers (1,400 miles) thick, and is located 2,890 kilometers (1,400 miles) beneath the surface of the Earth. As hot as a journey to Verne’s center of the earth might have been, a visit to the real location would be worse. The hottest region of the outer core is about 3,730-7,730 degrees C or 6,740-13,940 degrees F. In terms of size, the inner core’s radius is about 1,220 kilometers (768 miles).
