Anonymous users2024-02-12The content of the geography mantra of the first year of junior high school is as follows:1. Characteristics of warp and weft.
The north and south are meridians, and they are equal circles opposite.
The lengths are all equal, and the shape is semicircular.
The east and west are the parallels, forming parallel circles.
The length is not equal, and the shape is a circle.
The equator is the longest, and the polarization is a point.
2. The shape and size of the earth.
The Earth is a large sphere, with an area of 100 million square kilometres.
The radius is six thousand three hundred and seventy-one, and the circumference of the equator is about forty thousand.
Earth's axis: The Earth's axis of rotation.
Parallel: A circle perpendicular to the Earth's axis and orbiting the Earth. The equator is the largest weft coil.
Warp: A semicircle that connects the north and south poles and intersects perpendicular to the parallels.
3. Determination of latitude and longitude.
An increase to the north is the northern latitude, and an increase to the south is the southern latitude.
An increase to the west is the west longitude, and an increase to the east is the east longitude.
After judging well, add letters, east e west w north n south s.
4. The division of the east, west, north and south hemispheres.
Twenty degrees west longitude, one hundred and sixteen east longitudes.
Cut down with one knife, east and west hemispheres.
The northern and southern hemispheres are divided, and the equator is at zero latitude.
The northern latitude is the northern sphere, and the southern latitude is the southern sphere.
5. The alternation of day and night and the change of seasons.
The rotation of the earth, the change of day and night, the difference in time.
It revolves around the sun, the four seasons appear, and the five belts are divided.
From west to east, the direction remains the same, and the north is against the south.
One day of rotation, one year of revolution. Rotation center.
Earth's axis. The center of revolution is the sun.
6. Schematic diagram of the rotation of the earth.
Schematic diagram of the earth's revolution, time must be remembered.
Two to date twenty-two, two minutes to the date minus one.
The winter solstice sun shines southward, the days are short and the nights are long.
On the summer solstice, the sun shines northward, and the days are long and the nights are short.
The spring and autumn equinoxes shoot at the equator, and the global day and night are as long.

Anonymous users2024-02-111. The characteristics of the earth slip smoothlyThe equator is slightly bulging, and the poles are slightly flattened.
Around the earth's axis, it turns from west to east.
The north and south are meridians, which are relatively formed in circles.
The east and west are the parallels, forming parallel circles.
The equator is about 40,000, and the poles are reduced to points.
2. The division of the hemisphere is smoothTwenty degrees west longitude, one hundred and sixteen east longitudes.
Cut down with one knife, east and west hemispheres.
The northern and southern hemispheres are divided, and the equator is at zero latitude.
The temperate zone of the four seasons is obvious, and the north and south are reversed.
3. Day and night and the smooth flow of the four seasonsThe earth rotates, changing day and night.
Orbiting the sun, the four seasons appear.
One day of rotation, one year of revolution.
From west to east, the direction remains the same.
4. The smooth passage of the five belts of the earthThe earth has five belts, all of which are divided by four lines.
Return to the intertropics, the polar circle is divided into cold and warm.
There are two cold temperatures, and the five belts have uneven temperatures.
5. The map is smooth to distinguish the directionThe map is oriented and placed squarely.
The upper north and the lower are the south, the left west and the right east.
The plot is easy to distinguish, but the graticule is more difficult.
The latitude guide is north, and the longitude coil is east and west.
Polar projection map, orientation is more special.
For the Northern Hemisphere, the heart is north and surrounded by south.
The north latitude is east and west, and the rotation is reversed.
For the Southern Hemisphere, the heart is surrounded by north and south.
The southern latitude circle is east and west, and the rotation goes in time.

3. The four ends of China's territory.
With the Heilongjiang River on his head, he stepped on the dark sand island of his great-mother.
Mouth drink the water of the confluence of the two rivers, Pamir.
Swing up and tail. 4. The names of China's 14 neighbors.
East Korea, North Mongolia, Northeast and Northwest Russia, West Hajita Abba, Southwest India and Nepal.
There is also Myanmar, Laos, and Vietnam in the south.
5. Administrative divisions of China.
Two lakes, two Guangzhou, two rivers and mountains, four cities and four rivers Fuji'an.
Yunnan-Guichuan. Mengqing, Shaanxi, Gansu, Xinzang, Liangning, and Hainan.
Hong Kong and Macao are my good rivers and mountains, and I look forward to reunion on the day of Taiwan's return.

2. Characteristics of the earth: the equator is slightly bulging, and the poles are slightly flattened. Around the earth's axis, it turns from west to east. The north and south are the slag line, which is relatively made up in a circle. The east and west are the parallels, forming parallel circles. The equator is about 40,000, and the poles are reduced to points.
