Answer:
Core is the tough central part of various fruits, containing the seeds, part of something that is central to its existence or character.
Explanation:
The outer core of the earth is the liquid layer about 2,260km thick. It is made of iron and nickel. There are three layers and core is one of them.
1.Crust
2 Mantle
3.Core
The transition between the inner core and outer core is approximately 5,000 beneath the earth's surface.
The Earth's innermost layer is known as the core or baryspher. This layer has a thinkness of about 3,500km. It is mainly made up of heavy metals, particularly nickel and iron (ferrum). This is why it is also known as nife (nickel+freeum). The boundary separating the mantle and the core is known as Gutenberg discontinuity named after German geophysicist Beno Gutenberg.
The temperature of core ranges between 3000 °c to 6000°c. Besides such a high temperature, the core is also subject to extremely high pressure.The metallic nature of the core lends magnetic properties to the earth. The core has two layer -the solid inner core and the liquid outer core . The outer core comprises semi-solid rocks. The inner core is solid. through temperatures her are the highest, the pressure of the overlying layers keeps the rocks in a solid state.
