What is the circumference of the Earth at the equator?

What is the circumference of the Earth at the equator?

24,901 miEarth / Circumference

Is Earth wider around the prime meridian or the equator?

Continuing in the same direction takes you along the 180th degree longitude line. This means that if the Earth was a perfect sphere, the length of the equator would be exactly twice that of the prime meridian.

What is the circumference of radius of the Earth?

Measured around the Equator, it is 40,075.017 km (24,901.461 mi). Measured around the poles, the circumference is 40,007.863 km (24,859.734 mi).

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.

Who measured the Earth’s circumference?

The Greek philosopher Aristotle (384-322 B.C.) is credited as the first person to try and calculate the size of the Earth by determining its circumference (the length around the equator) He estimated this distance to be 400,000 stades (a stadia is a Greek measurement equaling about 600 feet).

How is prime meridian different from Equator 6?

The main difference between Equator and Prime Meridian is that Equator is the line circling the Earth halfway between the North and South poles while Prime Meridian is the line that runs through Greenwich, England.

What is the distance of A from the prime meridian?

The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere….Vocabulary.

Term Part of Speech Definition
Airy-0 noun crater on Mars which marks the prime meridian on that planet.

What is the circumference of the Earth at the 45th parallel?

At the equator, the circumference of the Earth is 40,070 kilometers, and the day is 24 hours long so the speed is 1670 kilometers/hour ( 1037 miles/hr). This decreases by the cosine of your latitude so that at a latitude of 45 degrees, cos(45) = . 707 and the speed is . 707 x 1670 = 1180 kilometers/hr.

What is the circumference of the Earth at the 40th parallel?

For example, at Columbus (Latitude 40-degrees North): Circumference of the Earth at 40-deg North = 30,600 kilometers. Time to complete one Rotation = 24 hours. Speed of Rotation at 40 North = Distance/Time = 30,600 km / 24 hr = 1280 km/hr.

What is the Earth’s circumference at the Arctic Circle?

Geography. The Arctic Circle is roughly 16,000 km (9,900 mi) in circumference. The area north of the Circle is about 20,000,000 km2 (7,700,000 sq mi) and covers roughly 4% of Earth’s surface.

What’s the circumference of the sun?
