What is the equatorial and polar diameter of the earth?

What is the equatorial and polar diameter of the earth?

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).

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.

Is polar diameter shorter than equatorial diameter?

The polar diameter of the earth is shorter than equatorial diameter by about- No worries!

What is the value of polar diameter?

From the available mathematical data the equatorial diameter of the earth is about 12756 km and also the polar diameter of the earth is about 12713.6 km.

What’s the difference between polar and equatorial radius?

The equatorial radius of earth is over its polar radius that is 6378 km. The earth’s polar radius is the distance from its center to the North and South Poles. Complete answer: The polar radius is the distance from the middle to the surface along that axis.

Why the polar diameter and the equatorial diameter of the Earth are different?

Complete answer: Earth is more extensive in the center and complements at the posts than an ideal circle. The equatorial width of Earth is around 7926 miles or 12,756 km while the polar measurement is 7900 miles or 12,714 km.

Why is it called polar?

The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.

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).

What are polar means?

ˈpō-lər. : of or relating to a geographical pole or the region around it. : coming from or having the characteristics of a polar region. polar cold. : of or relating to one or more poles (as of a magnet)

Why is the Earth’s diameter larger at the equator?

Earth is slightly smaller when measured between the North and South Poles which gives a diameter of 7,907 miles (12,725 kilometers). Earth bulges out a bit more around the equator than around the poles because of its rotation (spin).

How is polar region different from equatorial region?

Due to the spherical shape of the Earth, sunlight falls on different parts at different angles. Direct and focussed sun rays falls on the equator and hence, the regions here are hotter and warmer. The polar regions receive diffused sun rays, which is why the areas there are colder.

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.

What is the diameter of Earth?

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

What is difference between pole and equator?

The two places where the rotation axis intersects the surface of the sphere are the poles (the North Pole and the South Pole). The equator is defined as the intersection of the surface of the sphere with a plane (the equatorial plane) that passes through the center of the sphere and is orthogonal to its rotation axis.

What is the size of the Earth?

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.

Why is the equator hotter than the 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.

Which is greater the equatorial radius of Earth or the polar radius?

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.

What is equator and pole of Earth?

The equator represents the zero degree latitude. Since the distance from the equator to either of the poles is one-fourth of a circle round the earth, it will measure ¼th of 360 degrees, i.e. 90°. Thus, 90 degrees north latitude marks the North Pole and 90 degrees south latitude marks the South Pole.

What is equator and polar region?

1) Equator is proper alteration of day and night whereas not polar region is do not have . 2) Climate in polar is extreme cold and frozen whereas equator is hot. 3) Rainfall occur on equator and snow fall occur in polar region . 4)vegetation is very scanty in polar region , trees is not present .

Which is greater the equatorial radius of Earth or the polar radius?

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).
