How do you look at the graticule of geography in junior high school, and how do you look at latitude

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. ）

1. Longitude. Longitude is divided into 360 degrees, with 1 time zone every 15 degrees, of which 0 degrees is called the prime meridian, which is the first place to enter a new day, and then every 1 time zone to the west is 1 hour apart. For example, if it is 5 a.m., then one time zone to the west is 4 a.m., one time zone is 3 a.m., and so on, and the opposite is true to the prime meridian to the east, which means that the two sides of the prime meridian are exactly 23 hours apart.

From the equator to the poles, the latitudes are getting higher and higher. The equator is the dividing line that divides the northern and southern hemispheres.

Longitude and latitude 1 degree = 60 minutes = 3600 seconds, this sexagesim was customized by the ancient Babylonians, and we still use it today, as long as it is the same with regard to angles and circles.

2. Latitude. The latitude of the equator is 0°, which divides the planet equally into the southern and northern hemispheres.

Latitude refers to the line between a point and the center of the Earth's sphere and the angle of the Earth's equatorial plane, and its value is between 0 and 90 degrees. The latitude of a point located north of the equator is called north latitude and is denoted as n, and the latitude of a point located south of the equator is called southern latitude and denoted as s.

Areas with latitude values between 0 and 30 degrees are called low latitudes, areas with latitude values between 30 and 60 degrees are called mid-latitudes, and areas with latitude values between 60 and 90 degrees are called high latitudes.

The equator, Tropic of Capricorn, Tropic of Capricorn, Antarctic Circle, and Arctic Circle are special parallels.

Hello, 1, up north and down south, left west and right east. 2. The meridian extends in the east-west direction, and the latitude extends in the north-south direction. 3. In the latitude, the larger the northward to the north, the greater it is, indicating the northern latitude, and the larger the southward, the larger it is, indicating the southern latitude.

4. In the longitude, the greater the eastward it is, it means the east longitude, and the larger it is the westward, which means the west longitude. 5. Conclusion: a is 40 degrees south latitude and 40 degrees west longitude; b is 40 degrees north latitude and 40 degrees east longitude; c is 10 degrees north latitude and 170 degrees west longitude; d is 10 degrees south latitude and 170 degrees east longitude.

The view of the Geographic Graticule is as follows:

1. Judge the latitude to see the horizontal line (the degree on it), north and north latitudes, and south and south latitudes; North of the equator is the north latitude and south of the equator is the south latitude.

2. Judge the longitude to see the vertical line (the degree on it), the east longitude, the west longitude; The east of the prime meridian is the east longitude, and the west of the prime meridian is the west longitude; East of the 180-degree meridian is the west longitude, and west of the 180-degree meridian is the east longitude.

3. Judging the latitude of the northern and southern hemispheres, the northern latitude belongs to the northern hemisphere, and the southern latitude belongs to the southern hemisphere.

4. Judge the longitude of the eastern and western hemispheres, east of 20 degrees west longitude is the eastern hemisphere, and west of 20 degrees west longitude is the western hemisphere; East of 160 degrees east longitude is the Western Hemisphere, and west of 160 degrees east longitude is the Eastern Hemisphere.

5. Judge the low, middle and high latitudes to see the latitude, 0-30 degrees for the low latitude, 30-60 degrees for the middle latitude, and 60-90 degrees for the high latitude.

6. Judge the latitude, the tropic of cancer and the polar circle.

0 degrees of latitude: that is, the equator, is the longest parallel, the dividing line between the northern and southern hemispheres.

30 degrees of latitude: the dividing line between low and middle latitudes.

60 degrees latitude: the dividing line between middle and high latitudes.

90 degrees of latitude: that is, the north and south poles, 90 degrees north latitude is the north pole, and 90 degrees south latitude is the south pole.

Degree latitude: The Tropic of Cancer, which is the dividing line between the tropics and the temperate zone, and the dividing line between the phenomenon of direct sunlight and the phenomenon. The northern latitude is the Tropic of Cancer, and the southern latitude is the Tropic of Capricorn.

Degree latitude: The polar circle is the dividing line between the temperate zone and the cold zone, and there is the dividing line between the polar day and the polar night phenomenon. The northern latitude is the Arctic Circle, and the southern latitude is the Antarctic Circle.

The division of latitude is based on the equator as 0°, the south of the equator as the south latitude, the north of the equator as the north latitude, and the north and south poles are 90° north and south latitudes respectively (therefore, only the north and south latitudes do not need to be added after the equator 0°, and the others must be added n or s). Similarly, the closer you are to the equator, the lower the degree in latitude. Thus, the degrees are greater the further north in the Northern Hemisphere and smaller the further north in the Southern Hemisphere.

Hello, horizontal is latitude.

Questions. How to determine the degree.

From the middle equator to the north and south poles, it is 90 degrees each.

Questions. <>

Pick C is correct.

You find the equator first, and then you find the Tropic of Cancer.

Questions. Copy the answers.

I won't be able to do this kind of question.

The solid line next to the Tropic of Cancer is 30 degrees.

30 degrees north latitude.

The gradual increase of the meridian to the east is the east longitude.

So it's 90 degrees east longitude.

A meridian coil consisting of 20 degrees west longitude and 160 degrees east longitude.

You can't just remember what is dead, you have to understand.

The knowledge points of geography latitude and longitude in junior high school are as follows:

Latitude and longitude.

The variation of latitude increases from the equator (0° latitude) to the north and south poles; The maximum latitude is 90 degrees, at the South Pole, the North Pole.

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; Among them, 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).

How to read the graph: Observe the completion of the graph:

1) Find out the characteristics of the weft: all the wefts form a circle of their own, called the weft coils, the length of the weft coils is unequal, the longest is the equator, from the equator to the poles gradually shortened, to the poles shrink into a point. The parallels indicate the east-west direction, all parallel to each other, and the equator divides the earth into the northern and southern hemispheres.

(2) See the labeling method of latitude and the law of the distribution and arrangement of latitude: the latitude is calculated from the equator, the equator is set at 0 degrees, from the equator to the north pole and the south pole are divided into 90 degrees, and the north of the equator is the north latitude, and the code is n; To the south is the south latitude, the code is S, 90 degrees north latitude is the North Pole, and 90 degrees south latitude is the South Pole. The dividing line between southern and northern latitudes is the equator.

3) Special weft:

0 degrees of latitude: that is, the equator, is the longest parallel, the dividing line between the northern and southern hemispheres.

On the globe, the line connecting the north and south poles and perpendicular to the latitude is called the meridian, also called the meridian, the meridian is only the north-south direction, the longitude of the prime meridian is 0 degrees, which is the starting line of the meridian, from which to the east and west, each 180 degrees is called east longitude and west longitude, respectively E and W indicate that the 180 degrees of east longitude and west longitude coincide, usually it is called 180 degrees of meridian, any two meridians form a meridian coil, and any one meridian can divide the earth into two hemispheres.

The horizontal line (including the horizontal arc) is the parallel, and the vertical line (including the vertical arc) is the meridian line.

Latitude is from the equator (0°), south latitude (higher the further south), and north latitude (higher the further north);

Longitude is from the prime meridian (0°), east is east longitude (the further east the value is), and west is the west longitude (the further west the value is), the meridian is also called the meridian.

How to view the graticule:

Determine the east-west longitude and north-south latitude code.

Judging basis: Looking at the numbers, the east longitude is the east longitude that is getting bigger and bigger, the west longitude is the west longitude that is getting bigger and bigger, the north latitude is getting bigger and bigger, and the south latitude is getting bigger and bigger.

Step 2: Determine the direction.

Method: The warp refers to something.

Step 3: Judge the east, west, north and south hemispheres according to latitude and longitude.

Judgment of the Eastern and Western Hemisphere Mantra:

Longitude less than 20 degrees, all in the Eastern Hemisphere;

Longitude greater than 160 degrees, all in the Western Hemisphere;

The longitude is between 20 and 160 degrees, the east longitude is in the eastern hemisphere, and the west longitude is in the western hemisphere.

Judgment of the Northern and Southern Hemispheres:

The northern latitude is in the northern hemisphere and the southern latitude is in the southern hemisphere.

The horizontal is the latitude, the vertical is the longitude, the meridian is the north-south direction, and the latitude is the east-west direction.
