Whats is the diameter of the earth?
12,742 km
Earth/Diameter
What do you mean by equatorial diameter of the earth?
The Earth’s diameter at the Equator is about 12,756 kilometers (7,926 miles). The equatorial bulge means that people standing at sea level near the poles are closer to the center of the Earth than people standing at sea level near the Equator.
What is Earth’s approximate size?
about 24,901 miles
Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. Our planet’s shape, caused by the flattening at the poles, is called an oblate spheroid.
Why Earth is called a watery planet?
Earth is rightfully called a water-world: far more than half of our planet is covered in water. There’s also water underground, in rivers, and in the atmosphere. Collectively, all of this water forms Earth’s hydrosphere. That’s because the ocean covers 71 percent of Earth’s surface.
What is the difference between equatorial and polar diameter of Earth?
The difference in axes is about 1 part in 300. This means the earth’s equatorial diameter is 7,926 miles, while its polar diameter is 7,900 miles. Although the difference between equatorial and polar diameters is only 26 miles, the oblate shape of the earth complicates geographical matters.
How many Equators are there?
Nations Along the Line That Divides the Earth in Two The equator is an imaginary line that circles the Earth, splitting it into the Northern and Southern hemispheres.
What is the approximate diameter at the equator?
about 12,756 kilometers
The Earth’s diameter at the Equator is about 12,756 kilometers (7,926 miles). At the poles, the diameter is about 12,714 kilometers (7,900 miles). The Earth’s equatorial bulge is about 43 kilometers (27 miles).
How far is Earth from space?
Experts have suggested the actual boundary between Earth and space lies anywhere from a mere 18.5 miles (30km) above the surface to more than a million miles (1.6 million km) away.
Where is the earth’s circumference greatest?
the equator
Where is the Earth’s Circumference the Greatest? As the shape of the earth is an oblate spheroid, the diameter is different at the equator and at the poles. Since the diameter at the equator is greater than the diameter at the poles, hence, the circumference of the great circle at the equator is the greatest.
How big is the diameter of the Earth?
As a result, the latest measurements indicate that the Earth has an equatorial diameter of 12,756 km (7926 mi), and a polar diameter of 12713.6 km (7899.86 mi).
How big is the Earth at the equator?
Because of this, the diameter of the Earth at the equator is about 43 kilometers (27 mi) larger than the pole-to-pole diameter. As a result, the latest measurements indicate that the Earth has an equatorial diameter of 12,756 km (7926 mi), and a polar diameter of 12713.6 km (7899.86 mi).
How big is the Earth in relation to the Poles?
As a result, the latest measurements indicate that the Earth has an equatorial diameter of 12,756 km (7926 mi), and a polar diameter of 12713.6 km (7899.86 mi). In short, objects located along the equator are about 21 km further away from the center of the Earth (geocenter) than objects located at the poles.
How to calculate the circumference of the Earth?
Geometry tells us that the ratio of 1/50 is the same as the ratio of the distance between Syene and Alexandria to the total circumference of the Earth. Thus the circumference can be estimated by multiplying the distance between the two cities, 5000 stadia, by 50, equaling 250,000 stadia. How do we convert to kilometers?
