Also the second largest impact structure on Earth, the 1.85 billion years old Sudbury crater in Canada, hosts world-class mineral deposits - in this case nickel-rich minerals that were melted and concentrated by the extreme heating caused by the impact.
The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole â the meridional circumference â Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.
what is the earth s diameter in kilometers the diameter of the earth at the equator is 12756 32 kilometers or 7926 41 miles the diameter of the earth through the poles is 12715 43 kilometers or 7901 00 miles thu s the earth is 41 km or 25 miles wider than it is tall giving it a slight bulge at the equator this shape is known as an ellipsoid or more properly geoid earth like
