The direction of the Earth s rotation at the South and North Poles

The rotation of the Earth is an axis rotation in a counterclockwise direction when observed over the North Pole and clockwise when observed over the South Pole, which is customarily called west-to-east rotation.

The movement of the Earth is complex. The rotation of the Earth's axis and revolution around the Sun is the most significant, the most influential on the physical characteristics of the Earth, and the most well-understood motion.

The rotation of the Earth is an axis rotation in a counterclockwise direction when observed over the North Pole and clockwise when observed over the South Pole, which is customarily called west-to-east rotation. The rotation period is one day. The angular velocity of rotation is 15 degrees per hour, and the linear velocity varies depending on latitude and altitude, for example, the equatorial sea level is 464 ms, the altitude increases or decreases by 100 m, and the linear velocity increases or decreases by 26 m; The two poles are zero.

In addition to rotating around its axis, the Earth also revolves around the Sun in a certain orbit with a period of one sidereal year, about 365 days, 6 hours, 9 minutes, and 10 seconds. The direction of revolution is also from west to east, and the orbit is an ellipse with an oblateness of 1 60. The perihelion of the orbit is 100 million kilometers, the aphelion is 100 million kilometers, the average distance from the sun is 59 minutes per day, the average speed is kilometers per second, and the surface velocity is 14 square kilometers per day.

The first two of these have seasonal variations.

To put it simply, the north is reversed and the south is turned. Forward: clockwise, Counter: Counterclockwise.

The North Pole is counterclockwise, and the South Pole is clockwise.

The North Pole is the northern end of the Earth's axis of rotation, which is the point at 90°N.

The Arctic region refers to the Arctic Circle near the North Pole at 66°34 north latitude.

The region within the Arctic Ocean.

It is a vast frozen ocean, surrounded by numerous islands and North America.

and the coastal areas of northern Asia.

Icy waters carry icebergs from the Arctic Ocean into the Atlantic Ocean.

and the Pacific Ocean, the climate of the Arctic region is cold all year round, and in winter, the sun is always on the horizon.

Below, the sea is completely frozen in ice.

In summer, when temperatures rise above freezing, the edges of the Arctic Ocean melt and the sun hangs in the sky for weeks on end, the Arctic Ocean is rich in fish and plankton, which provides food for the millions of seabirds that nest here in the summer**, as well as for seals, whales and other marine animals.

Most of the area around the Arctic Ocean is relatively flat, no trees grow, the ground freezes in winter, the lead imitation ground is covered with a thick layer of snow, and in summer the snow melts, the topsoil thaws, and the plants grow and bloom, which are reindeer.

and animals such as musk oxen provided food.

Carnivores such as wolves and polar bears also survive by preying on other animals, and the Arctic is one of the most sparsely populated regions in the world, where the Inuit (formerly known as Eskimos) have multiplied for generations for thousands of years More recently, oil has been discovered here, so many people have come from the south to work.

Arctic Currents

The Arctic is a veritable world of ice and snow, but due to the movement of ocean currents, the sea ice on the surface of the Arctic Ocean is constantly drifting, cracking and melting, so it is impossible to accumulate thousands of meters of ice and snow over millions of years like the Antarctic continent. Therefore, the total amount of snow and ice in the Arctic is equivalent to 1 10 of the Antarctic, and most of it is concentrated in Greenland.

of continental ice sheets, while the Arctic Ocean sea ice, other islands and surrounding land contain only a small fraction of the permanent snow and ice.

The vast majority of the surface of the Arctic Ocean is covered by sea ice all year round, making it the only white ocean on Earth. Sea ice in the Arctic Ocean is on average 3 metres thick, covering 73 per cent of the total ocean area in winter, with an area of about 1,000,11 million square kilometres.

It covers 53 per cent in summer, or about 749,800 square kilometres. **Sea ice in the Arctic Ocean has been around for 3 million years and is permanent.

The direction of the Earth's rotation from the South Pole: The direction of the Earth's rotation is from west to east When viewed over the North Pole, the direction of the Earth's rotation is counterclockwise, and the direction of the Earth's rotation is clockwise over the South Pole

Earth is the third planet from the Sun and the only known celestial body that nurtures and supports life. Approximately the surface of the earth is a land mass made up of continents and islands. The remainder is covered by water, mostly oceans, bays, and other saltwater bodies, and the socks are also covered by lakes, rivers, and other freshwater, which together make up the hydrosphere.

Most of the Earth's polar regions are covered in ice. The Earth's outer layer is divided into several rigid tectonic plates that migrate to the surface over millions of years, while its interior remains active, with a solid iron core, a liquid outer core that generates the Earth's magnetic field, and a convective mantle that drives plate tectonics.

Physical properties of the Earth:

The shape of the Earth is roughly ellipsoidal, and the effect of the Earth's rotation causes it to be slightly flattened along the Earth's axis running through the poles and slightly uplifted near the equator. From the Earth's core, the Earth's equatorial radius is 43 kilometers (27 miles) higher than its polar radius. Thus, the farthest point on the Earth's surface from the center of mass of the earth is not Mount Everest, the highest elevation, but the summit of Mount Chimborazo in Ecuador on the equator.

The Earth's reference spheroid has an average diameter of about 12,742 km (7,918 mi), which is approximately equal to (40,000 km) This integer is not a coincidence, but because the unit of length in the meter, which was originally defined as one-ten-ten-ten-millionth of the distance between the equator and the North Pole on the meridian passing through Paris, France.

The value of gravitational acceleration at a certain sea level at the equator is ga=, the value of gravitational acceleration at a certain sea level in the North Pole is g=, the standard value of gravitational acceleration in the world is g=, and the earth's rotation period is 23 hours, 56 minutes and 4 seconds (sidereal days), that is, t=.

The direction of the Earth's rotation from the North Pole is counterclockwise, and the direction of the Earth's rotation from the South Pole is clockwise. The rotation of the earth refers to the rotation of the earth around the axis of rotation from west to east, the axis of rotation of the earth is at an angle to the ecliptic plane, perpendicular to the equatorial plane, the average angular velocity of rotation is degree seconds, and the linear speed of rotation on the earth's equator is 465 meters and seconds. The earth rotates at the same time, and it takes 23 hours, 56 minutes and 4 seconds to rotate in one cycle, and the rotation period of the branch increases or decreases by 3 thousandths to 4 thousandths of a second every 10 years.

1. Cannonball method.

The earth is constantly rotating, and objects moving horizontally on the ground must have a continuous right (northern hemisphere) or left (southern hemisphere) relative to each other. Based on this phenomenon, one can prove that the earth is rotating by analyzing the direction of the movement of the projectiles.

2. Gravity method.

The earth rotates constantly at all times, and due to the action of inertial centrifugal force, the gravitational acceleration of the ground must be the smallest at the equator and the largest at the poles; The Earth cannot be a positive sphere, but must be a spheroid with a slightly bulging equator and slightly flattened poles. The results of gravity measurements and radian measurements confirm the correctness of these views, which also confirms the rotation of the earth from one side.

The direction of the Earth's rotation is from west to east, counterclockwise over the North Pole and clockwise over the South Pole. The Earth's axis of rotation is angled to the ecliptic plane, perpendicular to the equatorial plane. The rotation of the earth is an important form of motion of the earth.

The position of the Earth's axis of rotation on the Earth's body is constantly changing, and this change is called the Earth's pole shift, referred to as pole shift. In 1765, L. Euler proved that if there were no external forces, the axis of rotation of the rigid Earth would oscillate freely around the axis of shape, with a period of 305 sidereal days. It was only in 1888 that the existence of pole shift was confirmed by the observation and hidden measurement of the change of the trace carrying degree of the weft digging.

In 1891, the United States Judgment S. C. Zhangdler further pointed out that the pole shift includes two main cyclical components: one is the free oscillation with a period of about 14 months, also known as the Zhangdler oscillation; The other is a forced swing with a cycle of 12 months.

The observed Zhangdeler swing is the free swing predicted by Euler. However, because the Earth is not an absolute rigid body, the period of Zhangdler's oscillation is about 40% longer than the period predicted by Euler. The amplitude of the Zhangdler oscillation varies slowly between approximately 410 440 days.

Another major component of pole shift is the annual forced oscillation, the amplitude of which is about and relatively stable, mainly due to seasonal variations in the atmosphere and ice and snow at the poles.

By removing the periodic component of the pole shift, a long-term pole shift can be obtained. The average velocity of the long-term pole shift is about years, and the direction is roughly around 70°W.

This sentence is not true.

The two points where the Earth's axis of rotation intersects with the Earth's surface are called the "Earth's Poles", the North Pole in the Northern Hemisphere, and the "South Pole" in the Southern HemisphereThe North and South Poles are the coldest regions on Earth.

The South Pole refers to the southernmost point of the Earth, at 90 degrees south latitude; The North Pole refers to the northernmost point of the Earth, at 90 degrees north latitude.

The Antarctic region refers to the area south of the Antarctic Circle, that is, south latitude to 90 degrees south latitude, and the Arctic region refers to the area north of the Arctic Circle, that is, north latitude to 90 degrees north latitude.

Generally speaking, what we usually call the North Pole can represent four meanings, namely the North Pole of the Earth's axis, the North Pole of the Earth's magnetic field, the North Pole of geography and the North Pole of the place name. The northernmost point of the Earth's axis of rotation here refers to the North Pole of the Earth's axis.

The direction of the Earth's rotation over the South Pole is Lu Liang clockwise, the direction of the Earth's rotation over the North Pole is counterclockwise, and the direction of Zhaosong is from west to east

Therefore, a
