Is the diameter of the Earth 4000 km?

Is the diameter of the Earth 4000 km?

Distance Information The diameter of the Earth at the equator is 12,756 kilometers (km).

How round is the Earth in KM?

The distance around Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles). Earth’s diameter is also wider at the Equator, creating a phenomenon called an equatorial bulge.

What is the diameter of Earth in both miles and km?

Earth’s circumference (the distance all the way around the equator) is 24,901 miles (40,075 kilometers). Its diameter (the distance from one side to the other through Earth’s center) is 7,926 miles (about 12,756 kilometers).

Is Earth 12742 km?

The shape of Earth is nearly spherical, with an average diameter of 12,742 kilometers (7,918 mi), making it the fifth largest of the Solar System’s planetary sized objects and largest among its terrestrial ones.

What layer of the Earth is 5000 km?

Inner core (5000 km – 6370 km below the Earth’s surface). 2 % of the Earth’s total mass.

How thick is the Earth?

Earth’s crust varies in thickness from 35 to 70 kilometers (22 to 44 miles) in the continents and 5 to 10 kilometers (3 to 6 miles) in the ocean basins.

Where is center of Earth?

Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles).

How old is Earth?

Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.

How fast does Earth spin?

With this information, to work out how fast Earth is spinning we need only our planet’s circumference. At the equator, its circumference is roughly 40,075 kilometres, so dividing this by the length of day means that, at the equator, Earth spins at about 1670 kilometres per hour.

What is Earth made of?

​​The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly com​posed of basalt.

Who found the diameter of Earth?

The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. Eratosthenes was born around 276 B.C., which is now Shahhat, Libya.

What is the size of Earth?

Who named Earth?

All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.
