Earth Science Recognize and write down the meridians, latitudes, and equators on the globe

Longitude: The line that connects the north and south poles and intersects perpendicular to the parallel, also known as the meridian. The meridian indicates the north-south direction; All the warp threads are semicircular and equal in length; Two warp lines facing each other form a warp coil; Any one warp coil can divide the Earth into two hemispheres.

Parallel: On the globe, the circle that circles the globe in the east-west direction is called the parallel. All the parallels are parallel to each other and perpendicular to the meridians, which indicate the east-west direction.

The size of the weft coil varies, with the equator being the largest latitude coil, and gradually shrinking from the equator to the poles, and then to the north and south poles to the points.

Equator: The equator is the longest circumference in the trajectory of points on the Earth's surface with the rotation of the Earth, about 40,700 kilometers long. If the Earth were to be considered as an absolute sphere, the equator would be equal to the north and south poles.

It divides the earth into the northern and southern hemispheres, with the northern hemisphere to the north and the southern hemisphere to the south, which is the baseline that divides latitude, and the latitude of the equator is 0

The tropic of cancer is the farthest point from the equator that the Sun can reach in the Northern Hemisphere.

A meridian, also known as a meridian, is defined as the arc of the north and south poles that connect this device and are perpendicular to the latitudes of the earth's surface.

and the warp thread perpendicular to it, called the weft. The weft is a circle of unequal length.

The longest latitude is the equator.

on the globe. The horizontal line is the parallel line.

The vertical bars are the warp lines.

The longest in the middle of the horizontal line is the equator.

Vertical are the meridians, and the meridians guide north, and there are countless meridians on the earth, and they are of equal length.

The horizontal line is the parallel, the latitude refers to the east and west, and the longest parallel is the equator, which is getting shorter and shorter from the equator to the two levels.

Summary. Hello dear

The equator is the dividing line between the southern hemisphere and the northern hemisphere, which divides the earth into two hemispheres, north of it is the northern hemisphere, 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.

Is there a line on the globe that represents the equator? What is the dividing line of what it is?

The equator is the dividing line between the southern hemisphere and the northern hemisphere, which divides the earth into two hemispheres, the northern hemisphere to the north and the southern hemisphere to the south, which is the baseline that divides the latitude. The equator has a latitude of 0°, which is the longest latitude on Earth. At the same time, the equator is the least gravitational acceleration on Earth.

The equator (equator), a basic geographical term, refers to the longest circumference line in the trajectory of a point on the earth's surface that follows the rotation of the earth. Its semi-amusement is a diameter with a circumference of kilometers.

The meridians and parallels were drawn on globes and maps in order to determine the position and direction on the earth, and there were no lines on the ground.

The latitude and longitude lines are perpendicular to each other. The weft is a circle of varying lengths. The longest parallel is the equator. The meridians are arcs of equal length that connect the north and south poles. Because the meridian indicates the north-south direction, the meridian is also called the meridian.

Internationally, the meridian passing through the original site of the Greenwich Observatory in the United Kingdom is called the 0° meridian, also known as the prime meridian. On Earth, the meridian lines indicate the north-south direction, and the latitude lines indicate the east-west direction. Dividing line between the eastern and western hemispheres: 160° east longitude and 20° west longitude.

The criss-crossing lines on the globe are the latitude and longitude lines.

Huainanzi Topographical Training" said: "Where the terrain is the latitude from east to west, and the north and south are the longitude. Therefore, the arc of equal length connecting the north and south poles is called the meridian.

The latitude and longitude lines are perpendicular to each other. The weft is a circle of varying lengths. Because the meridian indicates the north-south direction, the meridian is also called the meridian.

Internationally, the meridian that passes through the original site of the Greenwich Observatory in London, England is called the 0° meridian, also known as the prime meridian. The parallels indicate the east-west direction. The 0° parallel, also known as the equator, is the largest parallel.

The meridians and parallels were drawn on globes and maps in order to determine the position and direction on the earth, and there were no latitude and longitude lines on the ground.

1. Latitude and latitude People call the center of the earth's axis the center of the earth. The plane that passes through the center of the earth and is perpendicular to the earth's axis is called the equatorial plane. The large circle where the equatorial plane intersects the Earth's surface is called the equator. On the earth's surface, any circle parallel to the equator is called a coil of latitude or parallel.

2. Longitude and longitude The large circle that passes through the poles and is perpendicular to the equator is called the meridian coil or meridian, also known as the meridian. Since all the meridians intersect the north and south poles and are perpendicular to the parallels, any meridian represents the north-south direction of the earth. The longitude of a point on the earth is the angle between the plane of the meridian and the plane of the prime meridian where the point is located.

3. The latitude and graticule lines on the graticule globe together form the graticule. With graticules and their latitude and longitude, the location of various points on the earth is easily determined. Two different locations on Earth can have the same latitude or longitude, but it is not possible to have both the same latitude and the same longitude.

Therefore, different places and different positions on the earth can be represented by corresponding latitude and longitude.

The statement about the latitude and longitude lines on a globe is true: all the meridians are equal in length.

What is a globe:

A globe, i.e. a model of the Earth. The globe is to make it easier to understand the earth, and people imitate the shape of the earth, shrink it according to a certain scale, and make a model of the earth - the globe. The deformation of length, area, direction, and shape is provided on the globe, so it is correct to observe the interrelationship of various scenes from the globe as a whole.

Origin of the globe:

The world's first surviving globe was invented in 1492 by the German navigator and geographer Beheim, and it is now preserved in the Nuremberg Museum. In 1480, when Beheim (1459-1507) first visited Portugal as a Flemish merchant, he claimed to be a pupil of the Nuremberg astronomer Miller, so he became a seafaring advisor to John II.

At that time, voyagers used astrolabes to determine the altitude of the sun, moon, and stars to calculate time and latitude. The use of brass instead of a wooden astrolabe may have been initiated by him. He may have sailed with D. Cow to the west coast of Africa (1485-1486).

After returning to Nuremberg in 1490, with the assistance of the painter Grokendon, he began to paint the globe he had designed, and in 1492 he completed a globe with a diameter of 20 inches.

1.There are countless lines of weft;

2.parallel to each other;

3.Indicate east-west directions;

degrees to 30 degrees are low latitudes, 30 degrees to 60 degrees are middle latitudes, and 60 degrees to 90 degrees are high latitudes. 90 degrees to the south and 90 degrees to the north;

5.The parallels are circles perpendicular to the meridians and circumferential around the Earth. coils vary in size;

6.Latitude is measured from the equator, which is 0 degrees and 90 degrees south and north. The north of the equator is called the northern latitude, which is denoted by "n"; The south of the equator is called the southern latitude, which is denoted by an "s". The two poles are 90 degrees north latitude and 90 degrees south latitude.

The meridian lines are semicircular in shape, indicating the north-south direction, intersecting at the north and south poles, and are all the same length.

The parallels are circular in shape, indicating the east-west direction, parallel to each other, and gradually shorter in length from the equator to the poles.

1.Two meridians facing each other can form a circle, that is, a meridian coil.

2.The greater the degree of latitude (the equator, i.e. 0 degrees of latitude, is the longest parallel; 90 degrees north and south latitude is the north and south poles, that is, a point, length = 0), but its length is shorter; Parallels of equal degrees (e.g., 30 degrees south and 30 degrees north latitude are the same length) are equal in length.

3.Follow a certain line of latitude all the way east (or west) and finally return to the same place; And follow a certain meridian all the way north (or south) and finally cannot return to the same place. Stand at the north pole and look around, all directions facing south; And standing at the South Pole and looking around, all directions are facing north.

They are all circles, and the planes on which they are located are parallel to each other. There can be an infinite number of parallels.

Starting from the equator, the latitude goes to the south, and the degree to the north gradually becomes larger Huqing, and the maximum trouser cavity is 90 degrees in front of Yuanzhou.

What are the characteristics of the weft with regret:

1 All the parallels are round.

2 The length of the correct parallels at the same latitude is the same, and the length of the parallels at different latitudes is not the same—decreasing from the equator to the north and south poles. The equator is the longest, with two poles.

3 All parallels are parallel to each other, indicating the east-west direction.

4 The equator equinoxes the Earth – the northern and southern hemispheres.

5. The parallels intersect perpendicular to the warp.

There can be an infinite number of weft threads.
