How deep is the earths inner core?
The Earth's core is that portion of the Earth which is composed primarily of iron (86 %) and Nickel (10 %) with a mixture of other elements making up the remainder. The Earth's core is split into two. The outer core, which is a liquid and the inner core, which is a solid. The Earth's core has a radius of approximately 3470 kmA with a total volume of 1.7502x1011 km3 This is separated into the inner and outer core with dimensions as follows: The inner core has a radius of 1220 kmA extending from the centre of the Earth approximately 6370 km below Earth's surface to 5150 km below the surface (the change from inner to outer core is marked by a density change known as the Lehmann discontinuity). The inner core has a total volume of 7.4207x109 km3. The outer core is approximately 2260 km thick extending from 5150 km below Earth's surface to 2890 km (the core mantle boundary or Gutenberg discontinuity) The outer core has a volume of 1.6760x1011 km3. Geophysicists believe that convection currents in the liquid outer core are responsible for Earth's magnetic field. It is also thought that the very high difference in temperature between the outer core and the mantle is responsible for the creation of deep mantle plumes which in turn cause hot spot volcanism such as that occurring in Iceland and Hawaii. There is however some debate about the existence of deep mantle plumes occurring within the geophysics community. For more information on the Earth's core, please see the related links.

How thick is the core?
The thickness of the inner core is 1,200 km. 1,200 km being the radius of the sphere known as the inner core.
How thick is the inner core of the earth?
The inner core of the Earth is approximately 1,200 kilometers (745 miles) thick. It is a solid metal sphere primarily composed of iron and nickel at extreme temperatures and pressures. The inner core is surrounded by the liquid outer core.
How much thicker is the outer core than the inner core?
The outer core is 2900-5100 km thickThe inner core is 5100-6738 km thick
How long is the core?
From the Wikipedia: "The outer core of the Earth is a fluid layer about 2,300 km ... thick" - With current technology, it isn't possible to go that deep AT ALL.If you just want a calculation based on a hypothetical machine, assume some speed, and then divide the distance by the speed.
How thick is earths inner core?
The inner core is 1216 km and made of solid iron. It is approx 5000 degrees C and it doesnt melt because of everything else pushing down on it.
The borders between the outer core and inner core is how many kilometers beneath the crust?
About 5115 km deep.
What is the depth of the of the inner core?
The outer boundary of the Earth's inner core is 5,150 km or 3,160 miles deep. Please see the related link.
What the thickness of the inner core?
The thickness of the inner core is 1,200 km. 1,200 km being the radius of the sphere known as the inner core.
How deep are the 4 layers of the Earth?
The four layers of the Earth are the crust, mantle, outer core, and inner core. The crust is the thinnest layer, ranging from about 5-70 km thick, while the mantle is about 2,900 km thick. The outer core is approximately 2,200 km thick, and the inner core is roughly 1,200 km thick.
How thick are the earths layers in km?
crust: average of 32 km thick mantle: 2900 km thick outer core: 2200 km thick inner core 1250 km thick
What approximate is the diameter of earths core?
Seismic data was used to estimate the radius of the Earths core. Inner = 1,221 km Outer = 2,259km Total = 3,480km Therefore an approximate diameter to the Earth core is 6,690 km or 4,325 miles. See related link for more information.
How thick is the earths outer core in Km?
2,300 km
the thickness of inner core?

How many km is the Earth's core?
The Earth's core is about 6,371 kilometers from the surface to its center. The outer core extends from about 2,890 km to 5,150 km below the Earth's surface, while the inner core extends from about 5,150 km to 6,371 km below the surface.
