What is the definition of the outer core of the Earth?

What is the definition of the outer core of the Earth?

The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth’s magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around.

What is the outer core simple definition?

outer core Noun. liquid, iron-nickel layer of the Earth between the solid inner core and lower mantle.

What is the outer core of the Earth short answer?

Answer: The outer core of the Earth is a liquid layer about 2,260 km thick composed of iron and nickel which lies above the Earth’s solid inner core and below its mantle. Its outer boundary lies approximately 2,890 km (1,800 mi) beneath the Earth’s surface.

What is the outer core kid definition?

The outer core is the outer layer of the core that is made of liquid iron and nickel. Since it is a liquid, the outer core can spin, and it does. This spinning causes the entire planet to be magnetic (think of a refrigerator magnet).

What is the outer part of the Earth called?

the crust
The outermost layer, called the crust, is solid, too. Together, these solid parts are called the lithosphere. Earth’s crust is made up of hard rocks. It is the only part of the Earth that humans see.

Where is the outer core of the Earth?

The Earth’s outer core is the second innermost layer, located between the inner core and the mantle. It contains mostly iron and nickel, which- due to lower pressure than existing at the inner core- are in the liquid form.

What is in the Earth’s core?

Earth’s core is made largely of iron, and it’s split into two parts: a small, crystallized ball of hardened iron at the center of the Earth, called the inner core, and a liquid outer core that surrounds the inner core with a “roiling mass of molten metal,” said Williams.

What is the boundary between inner core and outer core?

The core–mantle boundary (CMB) of Earth lies between the planet’s silicate mantle and its liquid iron-nickel outer core. This boundary is located at approximately 2,891 km (1,796 miles) depth beneath Earth’s surface.
