What is the exact radius of the earth?
What is the exact radius of the earth?
The radius of Earth at the equator is 3,963 miles (6,378 kilometers), according to NASA’s Goddard Space Flight Center in Greenbelt, Maryland. However, Earth is not quite a sphere. The planet’s rotation causes it to bulge at the equator. Earth’s polar radius is 3,950 miles (6,356 km) — a difference of 13 miles (22 km).

What is the radius of the Earth write in KMS?
The average radius of the earth is 6,371 km. The diameter of the earth in kilometers is 12,742 km.
What percentage of Earth’s radius is the crust?
The core forms only 15 percent of the Earth’s volume, whereas the mantle occupies 84 percent. The crust makes up the remaining 1 percent.

How much of Earth’s land do humans inhabit?
Human beings take up a lot of real estate — around 50-70 percent of the Earth’s land surface. And our increasing footprint affects how mammals of all sizes, from all over the planet, move.
What is the radius of the earth * 1 point?
Its equatorial radius is 6378 km, but its polar radius is 6357 km – in other words, the Earth is slightly flattened. Eratosthenes was measuring the polar radius, and his value (using the 0.15 km/stadium conversion) lies between the polar and equatorial values.
Which part of the Earth’s interior is the thickest?
core
The core is the thickest layer of the Earth, and the crust is relatively thin, compared to the other layers.
How thick is Earth’s crust?
Beneath the oceans, the crust varies little in thickness, generally extending only to about 5 km. The thickness of the crust beneath continents is much more variable but averages about 30 km; under large mountain ranges, such as the Alps or the Sierra Nevada, however, the base of the crust can be as deep as 100 km.
How many miles is it to the moon and back?
The moon is, on average, 238,855 miles away. So technically people are saying they love you 477,710 miles (the distance to the moon and back).
