When a planet rotates fast what happens to its equator?
At 100 mph faster, the equator would start to drown. Meanwhile, the added centrifugal force from spinning 1,000 mph faster means water at the equator would have an easier time combating gravity.
How fast are people spinning by the equator?
about 1,037 mph
(This area is also called the equator.) If you estimate that a day is 24 hours long, you divide the circumference by the length of the day. This produces a speed at the equator of about 1,037 mph (1,670 km/h). You won’t be moving quite as fast at other latitudes, however.
Why is Earth bulge at equator?
An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centrifugal force exerted by the rotation about the body’s axis. A rotating body tends to form an oblate spheroid rather than a sphere.
Does time move slower at the equator?
Clocks run slightly faster at the equator compared to the poles because the earth’s rotation produces a slight bulge at the equator. However, the earth is also rotating faster at the equator. These two effects compensate for each other exactly, causing clocks to actually run at the same rate in both locations.
Why did the Earth spin faster?
In fact, according to New Scientist, there is some proven correlation between global warming and a faster rotation. This is due to melting ice caps and rising oceans, which creates a change in the planet’s distribution of mass.
Is the ocean deeper at the equator?
In contrast to wind-driven surface currents, deep-ocean currents are caused by differences in water density. The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness.
Why does the equator make one rotation in one day?
Therefore the further you are from the axis of rotation, the faster that part must move to make one rotation in a day. The Equator is the furthest from the axis, so a point on the Equator would move faster relative to the axis than a point at high latitude. But ALL of them make one rotation in one day.
Does the Earth rotate faster at the equator or poles?
Since the planet must go through a full rotation every 24 hours (otherwise it wouldn’t be a day), you would move faster if you were at the equator rather than, say a point between the North Pole and the Equator. The circumference of the earth is 24,901 miles.
How many miles does it take to travel around the equator?
A point 100 miles from the axis travels about 600 miles every 24 hours (the circumference of a circle with a radius of 100). The equator is almost 4,000 miles from the axis, which means it needs to cover about 24,000 miles every 24 hours. This is approximately 40 times faster.
What is the angular velocity at the equator?
The angular velocity at the equator is the same as it is everywhere else on the Earth. However, the equator is the farthest from the axis the Earth rotates on. A point 100 miles from the axis travels about 600 miles every 24 hours (the circumference of a circle with a radius of 100).
