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.
About 2100 km.
Earth's core
The Earth's core is about 1200km thick. it is mostly iron, and is solid due to extreme pressure. The temperature can be up to 7000 degrees.
Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter Venus' diameter = 12,104km or 0.9488 x Earths Earth's diameter = 12,756km Mars' diameter = 6794km or 0.5323 x Earths Jupiter's diameter = 142,984km or 11.21 x Earths Saturn's diameter = 120,534km or 9.45 x Earths Uranus' diameter = 51,114km or 4.01 x Earths Neptune's diameter = 49,532km or 3.88 x Earths (Pluto's diameter = 2306km or 0.18 x Earths) I included Pluto on the end there, its not classed as a planet any more though, but a dwarf planet.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
Define Core Diameter Mismatch
no it is not true. there is solid iron and nickel in the Earths core
What is the approximate circumference of a circle that has a diameter of 25 yards
What is the approximate circumference of a circle that has a diameter of 25 yards
The diameter of Earth's core is approximately 6,900 kilometers (about 4,300 miles). The core consists of an outer liquid layer and an inner solid layer, with the inner core being about 1,220 kilometers (760 miles) in radius. Overall, the core makes up a significant part of Earth's total mass and plays a crucial role in generating the planet's magnetic field.
The approximate diameter of a circle whose circumference is 21cm is: 6.68cm
The approximate circumference of a circle with diameter fourteen centimeters is 44cm
