The division of north and south latitudes, how to learn geography well

North of the equator is the north latitude and south of the equator is the south latitude.

The main thing about learning geography is to think more and look at more maps, and it is not difficult to understand.

Actually, the main thing is interest.

When I was in junior high school, my geography teacher kept asking me questions, which made me very frightened, and then I hated geography more and more, and I didn't know how I passed the exam. So much so that I scored more than 30 points in the first geography exam in the first year of high school, and more than 30 points! ! Later, the penultimate person became a good friend, and I always wondered if there was a connection...

But magically, then I became obsessed with geography like an enlightenment, and I became more and more comfortable in geography, and my grades got better and better, and in my opinion, geography is the most interesting subject in the liberal arts. Later, when I went to university, I had a lot more time and traveled to a lot of places, and I became more and more fascinated by geography.

So you see, interest is such an important thing.

I can learn well with such a poor foundation, let alone you.

With the equator as the dividing line, the northern and southern hemispheres are divided into north and south latitudes.

South of the equator is the southern latitude and north is the northern latitude.

1. The earth's equator divides the northern and southern hemispheres, and the latitude of the northern hemisphere is the northern latitude, and the latitude of the southern hemisphere is the southern latitude.

2. The equator is the longest circumferential split line in the trajectory generated by the rotation of the earth's surface points. The radius of the equator is km, and the circumference of the equator is km. It divides the earth into two hemispheres, north of it and south of it is the southern hemisphere, which is the baseline that divides latitude.

3. The latitude of the equator is 0 degrees, which is the longest latitude on the earth. The equator is the place where the gravitational acceleration modulus is smallest on Earth.

North of the equator is the northern latitude, the low latitude is 0 degrees - 30 degrees, the middle latitude is 30 degrees - 60 degrees, and the high latitude is 60 degrees - 90 degrees.

South of the equator is the southern latitude, the low latitude is 0 degrees - 30 degrees, the middle latitude is 30 degrees - 60 degrees, and the high latitude is 60 degrees - 90 degrees.

It is bounded by the equator, south of the equator is the south latitude, and north of the equator is the north latitude.

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

40,076 km. The equator is south latitude to the south pole, which is 90° south latitude, and north is north latitude, which is 90° north latitude.

The equator (zero parallel) is north latitude and south latitude south latitude.

Ask for evaluation, there is no merit and hard work!

The equator is 0 degrees, the north of the equator is the north latitude, and the south of the equator is the south latitude, each with 90 degrees. The South Pole and the North Pole are 90 degrees south and 90 degrees north latitude, respectively.

Take the equator as the line, with the southern latitude above and the northern latitude below.

The Earth's equator divides the northern and southern hemispheres, and the latitude in the northern hemisphere is the northern latitude, and the latitude in the southern hemisphere is the southern latitude.

It is bounded by the equatorial line and divided into the northern and southern hemispheres. The north of the equator is the north latitude, and the south of the equator is the south latitude. The Tropic of Cancer is the line of latitude, the Tropic of Cancer is the line of 23 degrees 26 minutes south latitude, and the Tropic of Cancer is the line of 23 degrees 26 minutes north latitude.

The Tropic of Cancer is the farthest distance that direct solar energy reaches. The Tropic of Cancer passes through Guangzhou and Yunnan in China.

The longest line of latitude crossing our country is the line of 40 degrees north latitude.

China's southernmost Nansha Islands' Zengmu dark sand is located at about 4 degrees north latitude, and the northernmost Mohe River is located at about 53 degrees north latitude.

East-West Warp. It is bounded by 160 degrees east longitude and 20 degrees west longitude, and is divided into the eastern and western hemispheres.

0 degrees east longitude coincides with 0 degrees west longitude, and the 0 longitude line passes through the Greenwich Observatory in London, England. The line of 0 longitude to the east is the east longitude, and to the west is the west longitude. The 180 degrees east longitude coincides with the 180 degrees west longitude, and this line is called the International Date Line, which passes through the East and West Polylia Sea and the Pacific Ocean in Russia.

The east longitude is 120 degrees through Beijing, China.

The westernmost part of China is located at about 75 degrees east longitude, and the easternmost point is about 135 degrees.

On the north and south sides of the equator, many circles parallel to the equator are drawn, which are called "latitude circles"; The line segments that make up these circles, called parallels, have an equatorial dimension of 0, south of the equator and north of the equator are north latitudes, and the farther away from the equator is the higher the dimension.

The earth can be seen as an approximate sphere, and the graticule and the earth's axis are both imaginary things, and after the graticule comes out, people can determine the position of any point on the earth.

The meridian, also known as the meridian, is the curve that connects the north and south poles of the earth, such as the 0-degree meridian at the Greenwich Observatory in London, also known as the prime meridian, which forms a circle with its corresponding 180-degree meridian. The east of the 0 degree meridian is called the east longitude, and gradually increases to 180 degrees east longitude to the east; The west is called the west longitude, and it gradually increases to 180 degrees west longitude to the west. 180 degrees west longitude and 180 degrees east longitude are actually the same meridian.

The latitude is much simpler, with 90 degrees in the north and south of the equator, increasing from north to south. 90 degrees south latitude is actually a point, the south pole; The same is true at 90 degrees north latitude.

It should be noted that two meridians that correspond to each other form a circle, and they are of the same size; Any one of the parallels forms a circle, but they vary in size.

When doing the question, a graticule diagram is generally produced, and the view is the same as the map, up the north and down the south, left west and right east. The horizontal line is the latitude line (there are also difficult people, marking the horizontal line as E or W, in fact, the map is deliberately reversed, and it will be wrong if you are not careful.) It's good to turn the topic upside down).

Practice more and believe you will become proficient.

The law of latitude changes: from the equator (0° parallel) to the north and south poles. The maximum latitude is 90 degrees, at the South Pole, the North Pole. Knowledge of geography.

The latitude north of the equator is called north latitude and is denoted by "n"; The latitude south of the equator is called southern latitude and is denoted by an "s".

With the equator as the boundary, the earth is divided equally into two hemispheres, the northern hemisphere north of the equator and the southern hemisphere south of the equator.

The variation of longitude increases from the prime meridian (0° meridian) to the west and east to 180

The longitude east of the prime meridian is called east longitude, which is denoted by "e"; The longitude west of the prime meridian is called west longitude, which is denoted by "w".

The dividing line between the eastern and western hemispheres is: a meridian coil composed of 20°W and 160°E.

West of 20°W to 160°E belongs to the Western Hemisphere (greater than 20°W or greater than 160°E).

East of 20°W to 160°E belongs to the Eastern Hemisphere (less than 20°W or less than 160°E).

1. In the same northern hemisphere, the latitude value is greater in the north;

2. In the same southern hemisphere, the greater latitude value is in the south;

3. At two points in the northern and southern hemispheres, the northern hemisphere is in the north and the southern hemisphere is in the south.

2. Use longitude to judge the east-west direction.

1. The same is in the east longitude, and the one with the greater longitude value is in the east;

2. The same is in the west longitude, and the one with the smaller longitude value is in the east;

3. The two places are the east and west meridians, compare the sum of the two:

4. If the sum is less than 180°, the east longitude is in the east; If the sum is greater than 180°, the west longitude is in the east.

The east longitude increases to the east, and the west longitude to the west increases.

The southern latitude increases in the south, and the northern latitude increases in the north.

n is north, s is sorth, e is east, and w is west.

Judging basis: Looking at the numbers, it is east longitude (e) that is getting bigger and bigger to the east, west longitude (w) that is getting bigger and bigger to the west, north latitude (n), and south latitude (s) that is getting bigger and bigger to the south.

Method: Arrow indication method.

According to the law of change of longitude and latitude numbers, draw arrows from small to large, and the arrows point to the corresponding latitude and longitude.

The meridians and parallels can also divide the earth into several different hemispheres. Like cutting a watermelon, the earth is cut along the equator (0°), and the hemisphere north of the equator is called the northern hemisphere; The hemisphere south of the equator is called the southern hemisphere, such as cutting the earth along the longitude of 20°W and 160°E, and the hemisphere from 20°W longitude to 160°E is called the Eastern Hemisphere; The hemisphere to the west is called the western hemisphere.

I'm a geography major.

The meridian is not what many people say, the vertical parallels are horizontal, and the definition of the meridian should be a semicircular arc from the South Pole back to the North Pole, and the two meridians can form a meridian coil. Whereas, the parallels refer to the closed circles that are parallel to the equator and orbit the earth.

When talking about how to look at graticule, we must first know that the main purpose of graticule is to accurately locate the direction.

In the judgment of the graticule, first of all, there is a simple law of longitude, that is, along the direction of the earth's rotation, the degree of east longitude is increasing, and the degree of west longitude is decreasing. There is also a law in the judgment of latitude, that is, from the south pole to the north pole, the degree of south latitude is decreasing, and the degree of north latitude is increasing. The warp and weft threads are interwoven into a graticule.

The main purpose of graticule is to locate and judge the direction, and there are two types of general questions in judging the direction.

1. From the side view of the earth, the most direct way to judge the relationship between the two locations is simply left, west, right and east.

2. Judging the direction from the pole is to use the method of inferior arc. (The first year of junior high school should be simpler, and the inferior arc method can not be mastered.) High school only requires. The rest is the same. ）
