pretty amazing cuz the answer is 7
The artic ocean
they are divided by the prime meridian and equaor
hotter
no
Half the distance in a straight line from one side of a planet to the other through the centre of the planet with the distance measured from the equaor on both sides. In other words, the radius of the sphere of the planet measured, not at the pole, but at the equator. It is important to distinguish between polar radius and equatorial radius because no planet is an exact sphere, but 'bulges out' at the equator because of 'centrifugal force' as the planet rotates. This is most marked in the gas giants of the solar system especially Jupiter and Saturn, which look distinctly flattened at the poles when viewed through a telescope, so that the polar radii are very much smaller that the equatorial radii.
The 0 degree line of latitude separates te northern and the southern hemispheres. It is called the Equator. Lines of latitude mark distances from equator to each respective pole. From 0 degrees latitude (the Equator), there are 90 degrees to each pole. Each degree of latitude is 60 nautical miles. 1 nautical mile is approximately 6,076 feet. So, 90degrees x 60nm/degree = 5,400 nautical miles from the Equator to a pole. This is a very rough calculation, because the Earth is not perfectly round. Be sure to remember, that a statute mile is 5,280 feet (rather than 6,076 feet). So, in terms of statute miles, the Earth's circumference is closer to 25,000 miles. Air and land navigation typically uses nautical miles or distance measurement. Speed is in nautical miles per hour (called "knots"). Lines of latitude are parallel to each other, so the distance between them is the same no matter how far you are from the Equaor. But, lines of longitude (from north pole to south pole) are not parallel -- the distance between them is greatest at the equator (basically 1 nm apart), but the instant you move north or south the distance starts shrinking as the lines of longitutde merge te closer you get to the poles.
