What is the geographical significance of the equator? What does the equator mean geographically?

The equator is the longest circumferential line in the trajectory of points on the Earth's surface that rotate with the Earth. Equatorial radius 6, equatorial circumference The equator is the acceleration of gravity on Earth.

The smallest place. The equator is a low pressure area, and the northeast and southeast trade winds blowing from both sides of the equator to the equator drive the sea water on the north and south sides of the equator to flow from east to west. The north is called the North Equatorial Warm Current, and the south is called the South Equatorial Warm Current.

When the equatorial warm current reaches the west coast of the ocean, it is blocked by land, and a small stream of it turns back to the east to form an equatorial countercurrent. Most of them are subject to geostrophic deflection forces.

It flows along the coast to higher latitudes, and is blown by westerly winds in the middle latitudes to form westerly drifting. When they reach the east coast of the ocean, part of them bends to lower latitudes along the west coast of the continent, becoming a compensating current for the equatorial warm current. The other part bends along the west coast of the continent towards high latitudes.

It constitutes the polar circulation. At the equator, flora and fauna grow faster, larger, and more bizarre than those found elsewhere. Equatorial region.

Sunlight is the most powerful energy on Earth. As the sunlight here vaporizes the oceans in large quantities, this shock creates columns of humidity over such a large area, which in turn form winds and undercurrents, which then eventually provide energy to life in unusually distant places.

Longitude is a point called the prime meridian, which is expressed in degrees to the east and west, and is another measure needed to accurately determine the orientation of a point on the earth's surface. The prime meridian or zero meridian is the meridian connecting the north and south poles through the original site of the Greenwich Observatory in the United Kingdom. Starting from the prime meridian, the degrees of the meridian gradually increase to the east and west until 180°.

Latitude and longitude are usually indicated on maps and globes and are used to locate any point on the planet. The Tropic of Cancer and the Tropic of Cancer are two particularly important lines. They are 23°27 north and south of the equator'places around the Earth.

The area between these two parallels is called the tropics. The Tropic of Cancer marks the northern limit of the tropics; The Tropic of Cancer is the southern boundary. The climate of this region varies greatly depending on the latitude and proximity to the sea.

Some places have a lot of rain, others are hot, dry and have little rain.

The equator is an imaginary line that runs from east to west around the earth at an equal distance from the north and south poles. The equator divides the Earth into two hemispheres, the northern and southern hemispheres. The equator is set at zero.

On the geomagnetic equator, the magnetic attraction from the south pole and the north pole is equal. On this east-west line, the needle of the compass is neither tilted north nor south. The geomagnetic equator does not strictly coincide with the geographic equator, because the north and south magnetic poles are also inconsistent with the geographic north and south poles.

The length of the circumferential line of the equator is about 40,000 kilometers. Latitude is a system of imaginary east-west lines called obscurity lines, which are lines that surround the earth and are parallel to the equator. Latitude uses latitude to measure the distance south of the equator and north of the equator.

From the equator to the south and north, the farther the distance, the greater the latitude, reaching the south pole and the north pole are both 90 degrees. There is also an imaginary line on Earth called the geomagnetic equator, or inclinationless line. The term leaning line comes from the Greek word meaning "not to lean to either side."

The equator is the lowest latitude coil with a degree of 0°, it is the dividing line between the northern and southern hemispheres and the starting line of the division of northern and southern latitudes. The equator is the longest coil of latitude and the largest circle, with a radius of about 6,378 kilometers and a circumference of about 40,000 kilometers. The saying "sitting on the ground and traveling 80,000 miles a day, surveying the sky and seeing a thousand rivers from afar" is an image description of the equator.

From the equator to the north and south poles, the length of the weft coil gradually decreases, and the north and south poles can be regarded as the two smallest weft coils. The maximum rotational linear velocity at the point above the equator: 1670 kmh.

As a result, the linear velocity of the other points on Earth begins to decrease towards the north and south poles. The geostrophic deflection force at the equator is minimal: 0.

12 hours. Taking 12 hours as the cut-off point, if the known day length (or night length) of a point is greater than 12 hours, it can be determined that the hemisphere in which the point is located is in the summer half year (or winter half year): vice versa.

The intersection of the equator and the morning line is at 6 o'clock at the meridian and at 18 o'clock at the meridian where the intersection with the evening line is located. These two points, as well as the intersection of the meridian coil and the equator passing through the "highest point", divide the equator into four equal parts, and the difference in longitude between each adjacent point is 90°, and the time difference is 6 hours, which is often used in time juice arithmetic.

The equator is the dividing line between the northern and southern hemispheres.

Do we habitually think that the days are long in the summer and short in the winter? But at the equator, there is no such distinction. This is because the equator is the largest circle of the earth's sphere, and the difference in the time of day and night between the four seasons formed by the yellow and equatorial angles cannot be reflected here.

<> there is a very special climate near the equator, that is, the tropical rainforest climate, which is hot and rainy all year round. This climatic zone is a densely forested area with a very rich variety of flora and fauna.

5 Things You Didn't Know About the Mini World.

1.Mini World pirates minecraft. It is said that similarity below 20 is borrowing, similarity at 20 40 is mild plagiarism, similarity at 40 60 is moderate plagiarism, and similarity at 60 80 is heavy plagiarism.

The similarity of the mini world above 90 belongs to copy and paste.

The equator is the name given to the ecliptic.

Modern astronomers call this the celestial equator. During the Han and Tang dynasties, the equator was used as the coordinates for observing the stars, and the ecliptic was used at the beginning of the Tang Dynasty. Hanshu.

Astronomical Chronicles: "The beginning of spring, the spring equinox, the east of the moon from the green road." The beginning of summer, the summer solstice, south from the equator.

The Book of the Later Han Dynasty is empty and withered. "The Second Chronicle of the Calendar": "The Zodiac Goes to the Pole" Liu Zhao notes the Han Zhang Heng "Armillary Sphere":

The equator crosses the belly of the heavens, and goes to the pole ninety-one degrees five-sixteenths. "The book. Hong Fan":

The trip of the sun and the moon has winter and summer" Tang Kong Yingda Shu: "The ** of the day, the middle place of the north and south poles is called the equator, and the north and south poles are ninety-one degrees each. ”

The modern equator is the longest circumference of the trajectory of the point on the earth's surface with the rotation of the earth, the radius of the equator; Radius of the poles ; Mean radius ; Equatorial circumference If the earth were to be regarded as an absolute sphere, the equator would be equal to the north and south poles, and it would be a great circle. It divides the geosphere into two hemispheres, north of which is the northern hemisphere, south of which is the southern hemisphere, which is the baseline that divides latitude, and the latitude of the equator is 0°The equator is the place with the least gravity on Earth.

The equator is the starting point of the north-south parallels (i.e., the zero degree parallel) and the longest parallels on Earth.

Anyone who has studied geography knows that the earth has an equator, which divides the earth into the northern and southern hemispheres, so do you know what the equator is?

The equator is an artificially divided line that divides the earth into two hemispheres, the northern hemisphere to the north and the southern hemisphere to the south, and the seasons of the northern and southern hemispheres are opposite.

The equator is also the baseline from which latitude is divided, and its latitude of 0° is the longest parallel on Earth. It can also be said that the equator is the longest circumference in the trajectory of the point on the earth's surface with the rotation of the earth, where the radius is kilometers and the circumference is kilometers.

In the equatorial region, the intense sunlight evaporates the oceans in large quantities, creating winds and undercurrents that eventually feed the lives of life in other distant places.

1. The equator, a geographical term, is the longest circumference line in the trajectory of the point on the earth's surface with the rotation of the earth. Its radius is and its circumference is kilometers. The equator is the dividing line between the northern and southern hemispheres, which divides the earth into two hemispheres, north of which is the northern hemisphere and south of which is the southern hemisphere, which is the baseline that divides latitude.

The equator has a latitude of 0°, which is the longest latitude on Earth. At the same time, the equator is the place where the acceleration of gravity on Earth is minimal.

2. The equator is the dividing line between the northern and southern hemispheres, and it is also the zero degree latitude on the earth. The equatorial region is tropical twice a year, with hot weather and high temperatures. The center of the equator coincides with the center of the earth, and it is also the longest coil of latitude on the earth, with a total length of more than 40,000 kilometers.

3. The equator passes through Gabon, Congo, Zaire, Uganda, Kenya, Somalia, Maldives, Indonesia, Ecuador, Colombia and Brazil. In these countries, people use different signs to indicate the equatorial line. In the Congo, for example, the equatorial line is represented by a number of small pillars arranged in a straight line, called equatorial piles.

The equator refers to the point on the Earth's surface, the longest circumference in the trajectory produced by the Earth's rotation. The equator is the dividing line between the southern hemisphere and the northern hemisphere, dividing the earth into two hemispheres, north of which is the northern hemisphere and south of which is the southern hemisphere, which is the baseline that divides latitude. At the same time, the equator is the place where the acceleration of gravity on Earth is minimal.
