Is there a difference between polar and equatorial diameter of Earth?

Is there a difference between polar and equatorial diameter of Earth?

The Earth’s equatorial diameter is 12,756 km, but from pole to pole, the diameter is 12,714 km, so there is a difference of 42 km .

Why is the equatorial diameter of the Earth is more than the polar diameter?

Earth is almost a sphere in shape but not purely a sphere, it slightly bugles at the equator. Therefore, the radius of the earth is different at both poles and equator. The equatorial diameter( twice of radius) is 12756 km but, the polar diameter is 12714 km. Was this answer helpful?

Which is greater the polar diameter or the equatorial diameter?

Equatorial vs Polar Diameter: 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).

What is the difference between equatorial and polar?

Equator is an imaginary line that divides the earth into southern hemisphere and northern hemisphere while the Polar diameters are measured from pole to pole.

What do you mean by polar diameter?

The diameter measured from pole to pole of the Earth is known as the polar diameter. The Earth is the third planet from the sun. The Earth’s diameter is only 12,742 km. It is the fifth-largest planet in terms of size. The poles are slightly flattened.

What is the definition of equatorial diameter?

“equatorial diameter” a telescope whose mounting has only two axes of motion, one parallel to the Earth’s axis and the other one at right angles to it.

Which is greater equatorial radius or polar radius?

Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) (equatorial radius, denoted a) to a minimum of nearly 6,357 km (3,950 mi) (polar radius, denoted b).

What is the main reason why the Earth’s equator is warmer than its polar regions?

Why is it hot at the Equator and cold at the poles? Sunlight hits the Earth most directly at the Equator. The curve of the Earth means that sunlight is spread over a wider area the further you move from the Equator. Sunlight hits a smaller surface area at the Equator so heats up quickly compared to the poles.

Why is the equatorial area warmer than the polar areas of Earth?

Because the sun’s rays hit the earth’s surface at a higher angle at the equator.

Which latitude line has the largest diameter?

The equator is the largest circle and divides the earth in half. It is equal in distance from each of the poles, and the value of this latitude line is zero.

Why polar regions are colder than equatorial?

Both polar regions of the earth are cold, primarily because they receive far less solar radiation than the tropics and mid-latitudes do. At either pole the sun never rises more than 23.5 degrees above the horizon and both locations experience six months of continuous darkness.

Why do polar and equatorial regions have different climates?

More heat from the Sun is received near the equator than near the north and south poles where the angle of the Sun’s rays is lower. This is why tropical climates differ so much from polar climates. Low rainfall, little or no vegetation due to lack of water.

What is the polar diameter of Earth?

The equatorial diameter Earth is about 7926 miles (12,756 km) while the polar diameter is 7900 miles (12,714 km).

What is the equatorial diameter of Earth?

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). Earth’s equatorial bulge is about 43 kilometers (27 miles).

What is polar in simple words?

When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don’t, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).

Is the equatorial radius bigger than the polar radius?

Shape of the Earth The Earth departs from a purely spherical shape in having an equatorial radius that is greater than its polar radius.

Is the polar circumference is larger than the equatorial circumference?

Earth’s circumference is the distance around 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).

Why is the equatorial area warmer than the polar areas of Earth?

Because the sun’s rays hit the earth’s surface at a higher angle at the equator.
