- The outer core of the Earth is a liquid layer about 2,266 kilometers thick. It is made of iron and nickel. This is above the Earth's solid inner core and below the mantle. Its outer boundary is 2,890 km (1,800 mi) beneath the Earth's surface.

- Outer Core. The Earth's outer core is made up of iron and nickel and is very hot (4400 to 5000+ degrees C). This is so hot that the iron and nickel metals are liquid! The outer core is very important to earth as it creates something called a magnetic field.uter Core. The Earth's outer core is made up of iron and nickel and is very hot (4400 to 5000+ degrees C).

Red Panda The red panda has small features like a cat but the markings of a panda or raccoon. In fact it looks like a cross between all three! It is reddish brown with a very thick ringed tail. Red pandas lives in Asia and shares some of its habitat with the giant panda.They both share some similar lifestyle facts. Both animals like to eat bamboo, although the red panda will supplement its diet and eat addition foods when available.hey even share breeding and reproduction characteristics. Despite all of their similarities, the red panda family classification is Ailuridae. Information on their life cycle in the wild is not complete. The red panda is also known as the lesser panda, fire cat, small red panda, and western red panda.

- At the center of the Earth lies a two-part core. The inner part is about the size of our moon, Marone says, and has a density of essentially steel. The outer core surrounding it is an ocean of liquid metal 2,300 kilometers thick. The Earth's rotation makes this ocean flow and swirl, and the moving metal generates the planet's magnetic field.

- Geologists think the temperature of Earth's outer core is about 6,700 to 7,800 degrees F (3,700 to 4,300 degrees C), and the inner core may reach 12,600 degrees F (7,000 degrees C), hotter than the surface of the sun.

Science for Kids The magnetic field the outer core creates goes way out in to space and makes a protective barrier around the earth that shields us from the sun's damaging solar wind. Inner Core. The Earth's inner core is made up of iron and nickel, just like the outer core, however, the inner core is different. The inner core is so deep within the earth that it's under immense pressure. So much pressure that, even though it is so hot, it is solid.

Earth's core The outer core of the Earth is a liquid layer about 2,266 kilometers thick. It is made of iron and nickel. This is above the Earth's solid inner core and below the mantle. Its outer boundary is 2,890 km (1,800 mi) beneath the Earth's surface. The transition between the inner core and outer core is approximately 5,150 km beneath the Earth's surface.

Physics for Kids At the center of the Earth spins the Earth's core. The core is made up of mostly iron. The outer portion of the core is liquid iron that spins and makes the earth into a giant magnet. This is where we get the names for the north and south poles.

What Are the Layers of the Earth Called? The outer core. The outer core is the next layer and surrounds the inner core. It is 1,806 miles from the Earth's surface and makes up 30.8 percent of the Earth's mass. Like the inner core, it is a molten liquid made mostly of iron and nickel. At 6,700 F, temperatures are slightly cooler in the outer core than the inner core.

Future of Earth The iron-rich core region of the Earth is divided into a 1,220 km (760 mi) radius solid inner core and a 3,480 km (2,160 mi) radius liquid outer core. The rotation of the Earth creates convective eddies in the outer core region that cause it to function as a dynamo.

Structure of the Earth! Inner Core. Temperature: 5,000°C - 6,000°C State: Solid Composition: iron and nickel The Earth’s inner core is a huge metal ball, 2,500km wide. Made mainly of iron, the temperature of the ball is 5,000°C to 6,000°C – that’s up to 6,000 times hotter than our atmosphere and scorching enough to make metal melt!

Earthâs Inner Core By measuring these seismic waves, scientists have been able to map out the size of the inner core. The inner core of the Earth is thought to be about 2,440 km across; about 70% the size of the Moon. It’s very hot, probably 3,000 to 5,000 Kelvin. Scientists once believed that the inner core was possibly a single, solid object; maybe even a single crystal of iron.

Earthâs Inner Core [/caption] Deep beneath the Earth lies the core. This is a ball of solid metal surrounded by liquid metal. The solid part is the inner core of Earth, and the liquid part is known as the Earth’s outer core. Scientists have long suspected that the interior of the Earth is much denser than the rest […]

About The Earth The core of the Earth has two distinct regions. There is a liquid outer core and a solid inner core. Both layers of the core are made of iron and nickel. The inner core is a giant furnace at super-high temperatures and pressures. The flowing metal of the outer core helps create a dynamo effect. Dynamos can create large magnetic fields. In the case of the Earth, the magnetic field protects our planet from space, solar winds and solar radiation.

What Is Earthâs Core Made of? The inner core, which is about 750 miles thick, is made primarily of iron. Unlike the outer core, the inner core is mostly solid. Although the iron in the inner core is even hotter (10,000º F or more — as hot as the surface of the Sun!) than the outer core, the intense pressure from the rest of the planet is so great that the iron cannot melt.

What Are Some Interesting Facts About the Outer Core? The outer core, one of the three layers of the Earth, is approximately 1,430 miles (2,300 kilometers) thick and between 7,200 and 9,000 F. According to National Geographic, the outer core is mostly composed of iron and nickel in a liquid alloy form.

Inner core The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius.[1][2] It is composed of an iron–nickel alloy and some light elements. The temperature at the inner core's surface is approximately 5,700 K (5,430 °C), which is about the temperature at the surface of the Sun.

How Do We Know the Temperature of Earthâs Core? Below the mantle, you’ll find Earth’s core, which is made up of two parts. There is a liquid outer core that surrounds a solid inner core. Scientists believe the solid inner core is a solid ball of iron and nickel that’s under a lot of pressure.

- Scientists believe that deep down inside the Earth, there’s a huge ball of liquid and solid iron. This is the Earth’s core, and it protects us from the dangerous radiation of space. The Earths interior (University of Chicago). When the Earth first formed, 4.6 billion years ago, it was a hot ball of molten rock and metal. And since it was mostly liquid, heavier elements like iron and nickel were able to sink down into the planet and accumulate at the core.

What Is Earth Made Of? 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). It is surrounded by a liquid, outer core composed of a nickel-iron alloy. It is about 1,355 miles (2,180 km) thick. The inner core spins at a different speed than the rest of the planet. This is thought to cause Earth's magnetic field.
