How do you determine the direction of the South Pole? How to determine the direction in the Antarcti

On the polar map of Antarctica, the southeast, northwest, and northwest should be judged according to the latitude and longitude lines, and the globe should be viewed from above the poles: the meridians are straight lines, the parallels are circles, the meridians indicate the north-south direction, the parallels indicate the east-west direction, and the center is the South Pole [Fig] 4 6 The general principle of judgment is that looking down on the earth over the South Pole rotates clockwise, and on the same meridian only the north and south (the same east-west direction); On the same parallel, only east and west are judged (the same direction is the same as north and south) [Fig] 5 6 If you are not on the same meridian or the same parallel, you must judge east and west and north and south, and the same direction of rotation is "east", and vice versa is "west" [Fig] 6 6 Approaching the South Pole is "southward", leaving the South Pole is "north", so judging from the South Pole according to this principle, then the South Pole is surrounded by "north", that is, there is no distinction between east, west, north and south.

If it happens to be at the South Pole, all directions are north, there is no south, and there is no east-west direction.

If it is a certain distance away from the South Pole, the direction towards the South Pole is South, and the direction away from the South Pole is North.

For the east-west direction, it can be judged by comparing the longitude values. Pay attention to use inferior arcs, not superior arcs.

The South Pole is the southernmost place on Earth, so the direction around him is north.

You don't need to judge the direction of the South Pole, but when you stand at the South Pole, you will be in the north in all directions.

Does this need to be said? Does this big guy know something? If you're standing at the South Pole, you don't have to tell the way.

Whatever direction you say is, point north.

Do you understand this? Because the earth is round, the north and south poles are there.

You can go out by standing on the North Pole, and the south direction is all south.

On the South Pole, the South Pole is the absolute south, surrounded by the north of the South Pole. On the North Pole, the North Pole is the absolute north, surrounded by the south of the North Pole. On the Arctic projection map (Arctic region map), the north is closer to the north and the south is farther to the south.

Clockwise along the inferior arc latitude is west, counterclockwise is east.

On the Antarctic projection map (Antarctic region map), the closest to the South Pole is the South and the farther is the North. The clockwise direction is east, and the counterclockwise direction is west. On the polar projection map, the center point of the Earth's clockwise rotation is the South Pole, and the counterclockwise center point of rotation is the North Pole.

To put it another way: the Earth rotates clockwise on the South Pole projection map, and the Earth rotates counterclockwise on the North Pole projection map.

There is only one direction on the South Pole and the North Pole, that is, North or South As for how to judge the east-west direction, look at the longitude, you can set the longitude as the east longitude is positive, and the west longitude is negative, subtract the latter longitude from the former longitude, and see the difference, if the absolute value is less than 180 degrees, then judge whether the former is located in the west or east according to the size of the value; Similarly, if the absolute value is greater than 180 degrees, it is the opposite of the previous judgment.

Determine the direction: First, look at whether the map is marked with latitude and longitude, the direction of latitude indicates the east-west direction, and the direction of the meridian line indicates the north-south direction. If the edge of the map is marked with a bearing mark, then the bearing arrow points to the north. If there are no markers on the map, then the top is north, the bottom is south, the left is west, and the right is east.

Interestingly, for any moving object on Earth, its direction of motion is affected by the Earth's rotation. This invisible influence is called the geostrophic deflection force. The geostrophic deflection force always has a tendency to cause the object to change its original direction of motion.

In the Northern Hemisphere, the deflection force causes the direction of the moving object to be deflected to the right; In the Southern Hemisphere, a left-side deflection occurs.

For this reason, the factor of bias forces is taken into account in many areas of engineering technology. For example, the launch of intercontinental long-range missiles, navigation and aviation all need to pay attention to correcting the effects of deflection forces, otherwise, it will not be possible to hit the target or accurately reach the destination.

On the polar map, it is necessary to judge the southeast, northwest, and northwest according to the latitude and longitude.

Looking down at the globe from above the poles: the meridians are straight, the parallels are circles, the meridians indicate the north-south direction, the parallels indicate the east-west direction, and the center is the south pole. Looking down on the Earth over Antarctica, it rotates clockwise**

1. On the same meridian, only north and south are judged (the east and west directions are the same);

2. Only east and west are judged on the same latitude (the north and south directions are the same);

3. Neither in a longitude nor a latitude to judge east, west and north and south.

The same direction of rotation is "east", the opposite is "west", near the south pole is "south", away from the south pole is "north", and the south pole is surrounded by "north".

Antarctic composition

Antarctica is divided into two parts: East Antarctica and West Antarctica. East Antarctica extends from 30°W to 170°E and includes Coates Land, Queen Maude Land, Enderby Land, Wilkes Land, George V Coast, Victoria Land, the Antarctic Plateau, and the Pole.

It covers an area of 10.18 million square kilometers. West Antarctica is located between 50°W and 160°W, including the Antarctic Peninsula, Alexandria Island, Ellsworth Land, and Bird Land, covering an area of 2.29 million square kilometers. Antarctica has only a few scientific expeditions and whaling teams from other continents.

Because the South Pole is the intersection of all meridians, and the meridians are in a north-south direction, at the South Pole, no matter which direction you look at, it is pointing in the direction of the North Pole, that is, the north direction. The South Pole is a very special position on the surface of the earth, it is one of the two points on the earth that has no directionality (the other point is the North Pole), standing on the South Pole, the east, west, and south directions are completely meaningless, and only the north direction This effect is theoretically only in the South Pole, and this situation does not exist in other regions of the Antarctic Circle.

At the South Pole, the sun only rises and sets once a year, the sun never sets for half a year, it is all daytime, the sun revolves around the South Pole in a place not high from the horizon, and it never sets, also known as "polar day", there is no sun for half a year, it is all night, also known as "polar night". The time at the South Pole actually uses "International Standard Time", or Greenwich Mean Time. The South Pole is covered with ice and snow all year round, with a thickness of 2,000 meters and an altitude of 2,800 meters. The climate is unusually harsh, with an average annual temperature of minus 48 degrees Celsius, an average summer temperature of minus 25-30, and the highest temperature ever recorded.

The average winter temperature is -55-60 minus, with the lowest temperature recorded below -zero and an average annual precipitation of 3 mm. The South Pole is not the highest point of the Antarctic ice sheet, and the snow and ice covering the South Pole move at a rate of about 10 meters per year, so scientists have to re-calibrate the latest position of the South Pole once a year to set a benchmark.

Ways to discern the direction of the North and South Poles:

1. If all directions are the North Pole at the South Pole, all directions at the North Pole are the South Pole.

2. Because the earth rotates from west to east, when you look at the top view, look at the north pole, counterclockwise. Antarctic, clockwise.

3. Use the compass and place the compass smoothly in the palm of your hand so that the pointer can rotate freely. The red arrow on the compass indicates the direction of north. Then, according to the order of "up, north, down, south, left, west, right, east", the direction of southeast, northwest is judged.

n for North; S stands for South.

The first thing to know is what the direction of rotation of the Earth is at the South Pole or the North Pole.

Over the North Pole, the direction of rotation of the Earth is counterclockwise and clockwise at the South Pole.

In addition, the direction of the Earth's rotation is known to be from west to east, so that the east-west direction can be discerned at the poles.

For example, you are given a map looking down over the North Pole to tell the east-west direction of the two places. First of all, determine that the direction of rotation of the earth is counterclockwise, in order to facilitate the problem, you can draw a line segment with an arrow, and the direction of the arrow pointing is the direction of the earth's rotation, that is, east. Of the two points, if one point is in the same position as the arrow pointing relative to the other point, then the point is east of the other point; The opposite is the West.

In this way, the east-west direction of the two places can be seen. In the Southern Hemisphere, it would be nice to change the direction of rotation to clockwise.

On the polar map, it is necessary to judge the southeast, northwest, and northwest according to the latitude and longitude lines.

Looking down at the globe from above the poles: the meridian is a straight line, the latitude is a circle, the meridian indicates the north-south direction, and the latitude line indicates the east-west direction of the dermabrasion beam. The center is the South Pole.

On the South Pole, it looks down on the Earth and rotates clockwise.

1.On the same meridian only north and south, (east and west directions are the same) 2Only things are judged on the same parallel. (Same in the north-south direction) 3It is necessary to judge neither in one longitude nor in one parallel, east and west, north and south.

The same direction of rotation is "East", and the opposite is "West".Approaching the South Pole is "southward", and leaving the Antarctic is "northward".The South Pole is surrounded by "North".

When standing at the South Pole, all directions are north. Because the North Pole is considered to be the northernmost point of the world, it is south in either direction, and in the same way, at the South Pole, all directions are north. Literally, in Chinese, Antarctica is the southernmost point of the earth.

In fact, it has many meanings such as Antarctica, South Pole, Antarctic continent, Antarctic region, and Antarctic circle. And geographically, the South Pole is the South Pole and the South Magnetic Pole.

The South Pole is located within Antarctica and is marked. However, due to continental drift, Antarctica has been far away from the South Pole for most of Earth's history; And, every once in a while, geographers revise the location of Antarctica. The last time the position of the South Pole was corrected was in the year 2000.

Antarctic geographic information

The South Magnetic Pole and the Unreachable Pole The South Magnetic Pole is the South Pole of the Earth's Magnetism, and the position of the South Magnetic Pole in 1985 was about 139°24 east longitude and 65°36 south latitude. The "Extremely Inaccessible" is a highland centered on 82°S latitude and 55° 60°E longitude, and due to its high terrain, it has become a major ice line for continental glacier outflow, and it is difficult to approach or reach the area.

In addition to the severe cold, the Antarctic region is also known as the "white desert" and "wind reservoir" on the planet, with an average annual precipitation of 55 mm in most areas, with the least precipitation occurring less than 5 mm and in the form of snowfall. The average annual wind speed is 17 18 ms and the maximum wind speed can reach 60 ms.

Because the South Pole is the end point of the South Pole.

The South Pole is a very special position on the surface of the earth, it is one of the two points on the earth that has no directionality (the other point is the North Pole), standing on the South Pole, the three directions of east, west and south are completely meaningless, and there is only one direction in the north.

At the South Pole, the sun only rises and sets once a year, the sun never sets for half a year, it is all daytime, the sun revolves around the South Pole in a place that is not high from the horizon, and it never sets, also known as "polar day", there is no sun for half a year, it is all night, also known as "polar night". The time at the South Pole actually uses "International Standard Time", or Greenwich Mean Time.

Features:

The South Pole is covered with ice and snow all year round, with a thickness of 2,000 meters and an altitude of 2,800 meters. The climate is unusually harsh, with an average annual temperature of minus 48 degrees and an average summer temperature of minus 25 30 degrees, with the highest temperature ever recorded. The average winter temperature is minus 55-60 degrees, the lowest recorded temperature is minus zero, and the average annual precipitation is 3 mm.

The South Pole is not the highest point of the Antarctic ice sheet, and the snow and ice covering the South Pole move at a rate of about 10 meters per year, so scientists have to re-calibrate the latest position of the South Pole once a year to set a benchmark.

The South Pole has no direction because it is located at the southernmost point of the Earth, so there is no direction to speak of. The South Pole is the closest place on Earth to the true South Pole, and it is only about 100 kilometers away from the southernmost point of the Earth.
