But just where is the North Pole? We know it's north.
The North Pole is at the top of the world. The South Pole is at the bottom of the world. Both are very cold, icy places. The Poles have six months of daylight and six months of night. The North and South Poles are at the top and bottom of the world.
Imagine a stick poking right through the Earth - this is called the axis. Now imagine the axis is tilted slightly. The Earth spins on this axis, which gives us day and night. Imaginary lines radiate out between the Poles: Lines of longitude radiate from each Pole.
There is also a geomagnetic North Pole, which is a very difficult scientific concept to understand. The geographic North Pole is located about km north of Greenland in the middle of the Arctic Ocean.
This is called true north. Most of the time, the North Pole is covered in sea ice. The North Pole has six months of daylight and six months of darkness. The magnetic pole is due to magnetic fields that are generated deep in the core of the Earth. These fields change slowly and flip from south to north on a very long time scale. The magnetic North Pole is about a km south of the geographic North Pole, although this is not fixed and changes each day.
When you look at a compass, it points to this point, so navigators must be aware of the difference between magnetic north and true north. It is generally thought that the first people to reach the North Pole were Robert Peary and Matthew Henson, with four Inuit guides, on 9 April , although it is suspected that they may have missed the actual spot by a few miles. Roald Amundsen was the first person to see both Poles. A geographic South Pole, a magnetic one, a geomagnetic one, and a ceremonial one.
The geographic South Pole marker is moved each year because the glacier on which it is located moves each year. It is the place from which the longitude lines on the map radiate out. Because the South Pole is on a glacier that moves about 10 metres a year, the marker has to be relocated each year, using satellite positioning systems. So even though the South Pole itself doesn't really move, the ice moves along with markers stuck in the ice, so the new place has to be marked each year.
A second expedition led by Robert Falcon Scott reached the Pole just five weeks later, on 18 January A sign that records the dates on which Amundsen and Scott each reached the Pole, and a quote by each, is also relocated each year. This sign is also relocated each year. It is a decorated copper pole surrounded by the flags of the twelve original nations that signed the Antarctic Treaty and have territory in Antarctica.
Because it is more elaborate, and would involve moving the flags also, this one is not moved each year. But it is the one that is photographed! It is the southern pole of the Earth's magnetic field, and its technical name is the south magnetic dip pole. It is at the point on the Earth where a compass needle, which is able to move vertically as well as horizontally, points straight up.
For that reason, the south magnetic pole is rarely found precisely at the real South Pole of the Earth. It varies by several kms a year and was last located precisely in when it was at Read other kidcyber pages about Antarctica.
