Can anyone help me with a few geography questions about latitude and longitude

1. The most consistent place with the poem "Sitting on the ground, traveling 80,000 miles a day, surveying the sky and looking at a thousand rivers from afar" is (c).

a、89°s 90°w b、40°n 80°e c、1°s，0° d、71°n 120°w

The circumference of the equator is about 40,000 kilometers, 1 kilometer and 2 miles, so the most consistent place is close to the equator (0 degrees), and c, 1 °s should be chosen

2. If four people set out from the North Pole at the same time, moving at a constant speed along the meridian lines of 0° 90° E 90° W and 180° respectively, they (c).

a. The direction of progress is different, and the distance between each other is getting farther and farther away.

b. The direction of progress is the same, and the distance between each other is getting farther and farther away.

c. Advance in the same direction and rendezvous at Antarctica.

d. The direction of progress varies, rendezvous at the equator.

The direction of progress is the same, both to the south; They get farther and farther apart, reaching the equator farthest, then getting closer and closer, and finally meeting at the South Pole. So choose C, go in the same direction, meet at Antarctica.

The first question is C, and there are 80,000 miles at the equator The second question is C, and the four meridians are perpendicular to each other to the south, and finally of course they meet at the South Pole.

Both are c, the first one is about the equator (the equator is 40,000 kilometers long), the second is about the length of the meridians (each one is the same length) and standing at the north pole in all directions to the south.

The eastern and western hemispheres are divided by a meridian coil consisting of 20 degrees west longitude and 160 degrees east longitude. North and South: 0 degrees of latitude.

Then take a look at your posting.

Dividing line between the eastern and western hemispheres: 20°W and 160°E

North and South : The equator, which is the 0° parallel.

a Diagram of the East and West Hemispheres.

Hemisphere, Southern Hemisphere of the Northern and Southern Hemispheres, Western Hemisphere of the Eastern and Western Hemispheres, Northern Hemisphere of the Northern Hemisphere

The longitude of point A is 85°e latitude is 20°s The longitude of point B is 170°e The latitude is 44°n The dividing line between the eastern and western hemispheres is 160° east longitude and 20° west longitude

East of 20°W longitude, west of 160°E is the Eastern Hemisphere, and vice versa is the Western Hemisphere.

The judgment of latitude and longitude is based on the judgment method of going up north and down south.

In a, the degree increases the further south you go, and this happens only in the southern hemisphere.

The longitude is judged according to the left-east-right-West German method, and in B, the longitude increases further east, which only appears in the east longitude range, and then it is extended that this place is 170° east longitude.

According to the different division criteria of the eastern and western hemispheres, it is deduced that the hemisphere to which the place belongs!

Figure Southwest, Figure B East.

Longitude 170° east, latitude 44°N

(1) Diagram A is located in the Eastern Hemisphere of the Eastern and Western Hemispheres, and the Southern Hemisphere of the Northern and Southern Hemispheres, Diagram B.

Located in the Eastern Hemisphere of the Eastern Hemisphere, the Northern Hemisphere of the Northern Hemisphere

2) The longitude of point A is 85° east longitude and the latitude is 20° south latitude

The longitude of point B is 170° east and the latitude is 44° north

It's mainly about where they go.

(1) South-east.

North (2) Point A is 85° east longitude and 20° south latitude

Point B is 170° east longitude and 44° north latitude

To illustrate the process!!

Look at the direction of this type of question, it is up to the north, down to the south, left to the west, and the right to the east.

1) Diagram A is located in the east.

The eastern hemisphere of the western hemisphere, the southern hemisphere of the northern and southern hemispheres, the western hemisphere of the eastern and western hemispheres, and the northern hemisphere of the northern hemisphere

The increase in longitude from left to right in Figure A proves that it is east longitude, and 85 degrees east longitude is located in the Eastern Hemisphere, and in Figure B, 170 degrees east longitude is located in the Western Hemisphere.

Diagram A decreases the latitude from bottom to top, which is 20 degrees south latitude, in.

The Southern Hemisphere, while the B diagram is enlarged from bottom to top, is 44 degrees north latitude, located in the Northern Hemisphere.

(3) Geographical coordinates of a: n75°E145°. Geographical coordinates of b: n55°e165°. A is in the Eastern Hemisphere and B is in the Western Hemisphere.

PS: According to the direction of increase (north increase, right increase), it can be judged as north latitude reading, west latitude reading. The Eastern Hemisphere is divided from 20° west longitude to 160° east longitude.

4) A: S55°W150°South temperate zone. B: S75°W170°Southern Arctic Zone.

Let's figure it out for myself.

Follow the habit of going up north and going down south.

Question 3a 75 degrees north latitude and 145 degrees east longitude.

b 55°N, 165°E.

a in the Eastern Hemisphere (from 20°W to 160°E), b in the Western HemisphereQuestion 4a 55°S, 150°W.

b 75°S, 170°W.

The climate is divided into five zones: south to north is tropical, to temperate (north and south), to 90 is cold (north and south), so a is in the south temperate zone, b is in the south cold zone.

Point A is in the Eastern Hemisphere and Point B is in the Western Hemisphere.

The dividing line of the Eastern Hemisphere is 20°W--0°-160°E, and the dividing line of the Western Hemisphere is 160°E--180°--20°W

Geographical coordinates of point A (55°S, 150°W).

Geographical coordinates of point b (75°S, 170°W).

Point A is in the southern temperate zone.

Point B is in the southern boreal zone.

Eastern HemisphereEastern Hemisphere.

Temperate and cold.

Question 1:

The middle and low latitude boundaries are 30° latitude, since it is the middle latitude to the south and the low latitude to the north, it must be 30° south latitude; The easternmost point of the Eastern Hemisphere is at 160° East Longitude, and the westernmost point of the Western Hemisphere is also at 160° East Longitude, since it is the Eastern Hemisphere to the west and the Western Hemisphere to the east, it should be the easternmost part of the Eastern Hemisphere and the westernmost part of the Western Hemisphere, so it is 160° East longitude, so, in summary, the answer is 30°S, 160°E.

Question 2: The earth itself is an oblate sphere, so the equator and the meridian are not the same length, a is not true; The meridians do converge at the north and south poles; On the same meridian there is only a north-south direction; The two meridians that form a sphere and a great circle can divide the earth equally, and c and d are wrong.

Question 3: The dividing line between temperate and cold zones: 66°34 N, 66°34 s; Dividing line between the eastern and western hemispheres: from 20°W east to 160°E is the Eastern Hemisphere, from 20°W west to 160°E is the Western Hemisphere; Dividing line between the northern and southern hemispheres:

0° (equator); Dividing line between middle and high latitudes: 60°N, 60°S

Hope it helps!

According to the figure, the shortest shadow is 2m, which is the same as the length of the rod, the altitude angle of the sun is 45°, the day is the winter solstice, and the direct sunlight is 23°26's, the local latitude is 90°-45°-23°26'=21°34'n。The shortest shadow is at 11:56 a.m. at noon and 12:56 a.m. Beijing time

4 minutes before 00, the local longitude is 1° east of 120°E (4 minutes for every 1° difference in longitude), which is 121°E.

The upright pole has no shadow, that is, the sun shines directly, the local area is in the tropics, and there are 2 direct rays in a year, so it should be equal time around the summer solstice. One occurs on June 8, 14 days before June 22 of the summer solstice, and the other should be 14 days after June 22, on July 6.

First of all, it must be assumed which time zone is used in the region, for example, if it is in China, Beijing time must be used.

Beijing time is assumed.

1. The longitude of the area is: 121°E.

Here's the explanation: Beijing time is 120°E longitude. When the sun shines directly in the area, the time is 11

56, and when 120°E is direct, the area has passed the direct sun point for 4 minutes. The longitude for 4 minutes is 1°, therefore, the longitude for this area should be 120°E+1°.

The explanation is as follows: December 22 is the winter solstice day in the Northern Hemisphere, when the Sun shines directly on the Tropic of Capricorn, that is, 23°27 s. At this time, the shadow length of the object at noon in the area is equal to the height of the object (both 2 meters), indicating that the solar altitude angle is 45°.

Then the latitude of region A is 90°-23°26 -45°=21°34 N.

Therefore, the geographical coordinates of the place are: 121°E, 21°34 N.

2. There is no shadow on the pole, indicating that the area is within the Tropic of Cancer. On the summer solstice, the sun shines directly on the Tropic of Capricorn, which should be June 21 or 22. The first time the area was without a shadow was on June 8, so it was 13 or 14 earlier than the day of return.

The second time the pole will be without shadow should be 13 days after the date of return (if it is June 21) or 14 days after the date of return (if it is June 22). Well, this date should be July 4 or 6.

1. Geographical coordinates (122°30'E, 21°34'N).

According to the inscription, on this day of the winter solstice, the sun shines directly at 23°26's;According to the figure, the shadow of the bamboo pole is in the northwest direction in the morning, due north at noon, and northeast in the afternoon, indicating that on this day, the sun rises from the southeast and sets in the southwest, and the sun is in the south direction of the place at noon, so the place should be located in the area north of the Tropic of Cancer (etc. When it is noon (12 o'clock) and Beijing time is 11:50, the longitude of the place is calculated to be 122°30'. again by 11; At 50, the rod length is 2m, and the shadow length is also 2m (i.e., the radius is 2m), and the noon solar altitude angle h=45° is obtained according to the tangent formula, and the local latitude is calculated as 21°34'n or 68°26's (located south of the Tropic of Capricorn, so it is excluded) from the solar altitude angle formula h=90°-the latitude difference between the local latitude and the direct point of the sun.

2. The pole has no shadow, that is, the sun is directly exposed to the place, the first time is the day, and the next time is the date symmetrical with the summer solstice, plus 14 days, it is July 6.

People have assumed a coordinate system for the earth's surface, which is the line of latitude and longitude. Longitude is the degree in which a point on Earth is east or west of a north-south alignment line called the prime meridian. 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.

Latitude and longitude is the combined name of latitude and longitude to form a coordinate system. Also known as the Geographic Coordinate System.

In order to accurately indicate the position of various places on the earth, people have assumed a coordinate system for the earth's surface, which is the line of latitude and longitude. So, how did the original latitude and longitude lines come about? How is it measured?

In 344 B.C., Alexander crossed the sea and invaded the south, followed by the eastward expedition, and the military geographer Nirkus searched for information along the way, preparing to draw a "map of the world". He found that the route of Alexander's crusade was similar from west to east, regardless of the change of seasons and the length of sunshine. An important contribution was made - for the first time on earth, a line of latitude was drawn from the Strait of Gibraltar and along the Torus and the Himalayas to the Pacific Ocean.

The meridian meridian, also known as the meridian, is an auxiliary line hypothesized by human beings for the convenience of measurement, and is defined as a semicircular arc on the great circle line connecting the north and south poles on the earth's surface. Any two meridians of equal length intersect at the north and south poles. Each meridian has its corresponding numerical value, called longitude.

The meridian indicates the north-south direction.

The origin of the name of the meridian: "In the stereoscopic motion trajectory of a certain day, the celestial body appears at the same time at each point on the same meridian in the upper middle heaven (noon) and the lower middle heaven (sub)." "Different warp threads have different places.

It is earlier in the easterly area and later in the westerly area.

Important warp:

Prime meridian.

Paris meridian.

180 degree warp.

20 degrees west longitude.

160 degrees east longitude.

Alexander's empire was short-lived and soon collapsed. But in the Egyptian city named after Alexandria, a famous library appeared, and Eratosthenes, who had been the director for many years, was very knowledgeable and proficient in mathematics, astronomy, and geography. He calculated that the circumference of the earth was about 46,250 kilometres and drew a map of the world with seven meridians and six parallels.

In 1519---1522, Magellan's fleet made a circumnavigation voyage through the Atlantic, Pacific and Indian Oceans, and finally returned to Spain, confirming that the Earth was a sphere and laying the foundation for latitude and longitude.

The latitude line, like the meridian line, is an auxiliary line assumed by human beings for the convenience of measurement, and is defined as the trajectory formed by the rotation of the earth at a point on the earth's surface. Any one of the wefts is round and parallel to each other. The length of the parallels is the circumference of the equator multiplied by the cosine of the latitude of the parallel, so the equator is the longest, and the farther away from the equator, the shorter the circumference, and it shrinks to 0 at the poles.

The parallels indicate the east-west direction.

Important wefts:

Arctic Circle (66 ° 33' 38" n）

Tropic of Cancer (23 ° 26' 22" n）

Equator (0°N).

Tropic of Capricorn (23° 26' 22" s）

Antarctic Circle (66°33' 38" s）
