What does inner core mean in science?

The inner core is a hot, dense ball of (mostly) iron. The temperature of the inner core is far above the melting point of iron. 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.

What is the definition of inner core in Science for Kids?

The inner core is the deepest and hottest layer of our planet. It’s about 4,000 miles below the surface. Scientists estimate that the inner core, composed of mostly iron and nickel, can reach temperatures up as high as a whopping 10,000 degrees Fahrenheit.

What things have a core?

An example of a core is the inner most part of our planet. An example of a core is the inside part of an apple that holds the seeds. To form or build with a base or innermost part consisting of a different substance from that of the covering or outer part. A fiberglass boat deck that is cored with wood.

What is a core in physics?

General Physics) a piece of magnetic material, such as soft iron, placed inside the windings of an electromagnet or transformer to intensify and direct the magnetic field.

What is core in our body?

The core is the center of our body and it functions to stabilize the trunk while the arms and legs move during functional movements. The system of muscles that make up the torso (on the front, the sides, and the back of the body). Muscles that stabilize the shoulders.

What is the definition of inner core in science?

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). It has an estimated radius of 1220 km (768 mi). Seismologist Inge Lehmann was the first to discover the inner core as being solid and covered by a liquid outer core.

What does the core mean?

core(Noun) The center or inner part, as of an open space; as, the core of a square. core(Noun) The most important part of a thing; the essence; as, the core of a subject. core(Noun) The portion of a mold that creates an internal cavity within a casting or that makes a hole in or through a casting.

What is the difference between the core and the crust?

The object has a “core” and “mantle” if material separated. The core is the high density stuff in the middle the mantel is the stuff around the core. One region is called the “core” because that region is inside of the “mantle”. The solid surface is called a crust because it is there and because we can see it.

What is the definition of core of the Earth?

Earth’s core is the very hot, very dense center of our planet . The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles). Planet Earth is older than the core.
