Is the equator closer to the center of the Earth?
In other words, if you’re standing on the equator, you’re 22 km further away from the center of the Earth than someone standing on the North Pole. So if you did want to dig that hole into the Earth, the shortest distance would be from the North or South Pole.
What is the equator of a sphere?
The equatorial plane meets the sphere in a circle called the equator. The line through the centre of the sphere perpendicular to the plane of a great circle meets the sphere in two points called the poles of the great circle. The poles of the equator are the north pole N = (0, 0,1) and the south pole S = (0, 0, —1).

Is there a relationship between equatorial diameter and period of rotation at equator?
On Earth. The Earth has a rather slight equatorial bulge: it is about 43 km (27 mi) wider at the equator than pole-to-pole, a difference which is close to 1/300 of the diameter. The rotation of the earth also affects the sea level, the imaginary surface that is used to measure altitudes from.
Why is it so hot at the equator?
Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth, the Equator is closer to the sun so receives more of its energy. The Equator has a smaller surface area so heats up quickly compared to the poles. This means more heat from the sun makes it to the surface of the Earth.
What is it like living on the equator?
If you live on the equator you will experience the quickest rates of sunrise and sunset in the world, taking a matter of minutes. While tropical areas along the equator can experience wet and dry seasons, other regions may well be wet for much of the year.
How many great circles can a sphere have?
There are an infinite number of great circles that can be drawn on any perfect sphere. The longitude lines on a globe all form great circles that pass through the same two points (the North Pole and the South Pole).
How does the equator divide the globe?
The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres. The prime meridian, or 0 degrees longitude, and the International Date Line, 180 degrees longitude, divide the Earth into Eastern and Western hemispheres.
Does an egg stand up on the equator?
During the spring and fall equinoxes, the sun appears directly overhead at the Equator, and the length of night and day are nearly equal worldwide. Some people believe that the gravitational pull of the sun on these days can help keep an egg standing on its end. This idea is unproven, but it’s fun to test.
Is Earth a perfect sphere?
Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.
Does the equator have 2 summers?
We DO have 2 summers and two winters – and 2 springs and autumns too. The varying distance between the sun and earth does not cause the seasons. They are caused by the tilt of the Earth towards the sun in summer and away from the sun in winter.
