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.
Well, here are some numbers to make you think again! The circumference of the Earth is about 40,000 kilometers or 24,900 miles. This refers to how big the Earth is around itâs fattest middle part, like if you were to measure the length of a string going around the center of the Earth at the equator.he total surface area of the Earth is about 500,000,000 square kilometers. âSurface areaâ refers to all of the area of the lands surface, such as oceans and continents. Itâs sort of like the total amount of space on the Earth that you could walk on or swim through.
