• ➡ Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). …… The pressure is nearly 3.6 million atmosphere (atm)….

What are two characteristic of core?

Core is the densest part of the Earth. It is divided into the inner and the outer core. The core of the Earth has a diameter of approximately 7000km. It is made up of Nickel (Ni) and iron (Fe) and thus it is also known as NIFE.

What are the 5 characteristics of the inner core?

5 Facts About the Earth’s Inner Core

• It’s Almost The Size of the Moon. The Earth’s inner core is surprisingly large, measuring 2,440 km (1,516 miles) across.
• It’s Hot…Really Hot.
• It’s Mostly Made of Iron.
• It Spins Faster Than the Surface of the Earth.
• It Creates a Magnetic Field.

What are the characteristics of the inner core and outer core?

The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.

What is known as core?

core. [ kôr ] The central or innermost portion of the Earth, lying below the mantle and probably consisting of iron and nickel. It is divided into a liquid outer core, which begins at a depth of 2,898 km (1,800 mi), and a solid inner core, which begins at a depth of 4,983 km (3,090 mi).

What is the use of core?

The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in die casting and injection moulding. For example, cores define multiple passages inside cast engine blocks.

What are the two characteristics of crust?

Summary

• Oceanic crust is thinner and denser than continental crust.
• Oceanic crust is more mafic, continental crust is more felsic.
• Crust is very thin relative to Earth’s radius.

What is the characteristic of crust?

Earth’s outer surface is its crust, a cold, thin, brittle outer shell made of rock. The crust is very thin relative to the radius of the planet.

What are characteristics of crust?

In geology, a crust is the outermost layer of a planet. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.

What core means?

A core, or CPU core, is the “brain” of a CPU. It receives instructions, and performs calculations, or operations, to satisfy those instructions. A CPU can have multiple cores. A processor with two cores is called a dual-core processor; with four cores, a quad-core; six cores, hexa-core; eight cores, octa-core.

What is an example of core?

An example of a core is the essence of a person and how they treat the world around them. 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.

What is your core?

The core consists of the muscles surrounding your trunk, including your abdominals, obliques, diaphragm, pelvic floor, trunk extensors, and hip flexors. Your core provides stability to the trunk for balance, plus movements like lifting weights and standing up from a chair.

What are some characteristics of the earth’s core?

– Seismic wave velocity. The velocity of the S-waves in the core varies smoothly from about 3.7 km/s at the center to about 3.5 km/s at the surface. – Size and shape. – Pressure and gravity. – Density and mass. – Temperature. – Magnetic field. – Viscosity.

What are the characteristics of core curriculum?

The characteristics of core curriculum are as follows: (i) It utilities the problems of personal and social development common to all youth. (ii) It develops these problems without reference to the traditional subject-matter fields. (iii) It encourages the use of the problem-solving technique to attack problems.

What are some characteristics of the outer core?

The outer core consists of molten metals and rock. The inner core is incredibly hot iron and nickel that is solid due to massive pressure. The inner core also spins, and that generates the magnetosphere.

What does the core of the Earth consist of?

The Earth consists of three layers: the crust where we live; the mantle, a layer of scalding-hot liquid rock; and the core. The core consists of a liquid outer core containing mainly nickel and iron and a solid inner core made up mostly of iron.
