Central America, abbreviation: Central America

The first division method.

The central region of the American continent south of Mexico and north of Colombia. It is bordered by the Caribbean Sea to the east and the Pacific Ocean to the west. It is a narrow land mass connecting South America and North America.

Seven countries including Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica and Panama are Spanish-speaking. It covers an area of 10,000 square kilometers. It has a population of about 25.37 million.

The second division method.

In addition to the forefront, the isthmus also includes Mexico and the West Indies: among them, the West Indies is a long chain of islands, extending from Mexico and the southern part of the Florida Peninsula in the United States, including the islands of the Bahamas, the Greater Antilles and the Lesser Antilles, to the northeast coast of South America, with an area of about 230,000 square kilometers and a population of more than 30 million.

The Americas include North America and South America.

Latin America: Latin America.

Latin America refers to the region of the Americas south of the United States, located between 32°42 north latitude and 56°54 south latitude, including Mexico, Central America, the West Indies, and South America.

For your question, America is indeed a general term for North and South America, Central America has an answer above, Latin America is the same as above, and the map is Central America.

1.Chinese (most widely spoken), English (widest available, Arabic, Spanish, French, Russian.

2.Central America: Mexico-Panama is a series of countries plus the Caribbean Sea nearby.

Weekly: North and South America.

Latin America: Mexico south of the week.

There are 6 types: Chinese, French, English, Russian, Spanish, Arabic.

America refers to the American plate that includes North and South America, Central America is Panama City of the Panama Canal, and the area of Mexico is also called the Central American Isthmus.

Latin America is the region of the Americas other than the United States and Canada.

The six working languages of the United Nations include the languages of the founding countries of the United Nations: Chinese, English, French, Russian, and later the most widely spoken languages: Arabic and Spanish.

America is the general term for North and South America. Latin America is the region south of the United States (i.e., the rest of the Americas excluding the United States and Canada). Central America is North America south of the United States, that is, a narrow strip of land north of South America and south of the United States.

Latin America is not divided according to geography, it is called Latin America because the people of those regions speak Latin American languages (Spanish, Portuguese, etc.).

The dividing line between North and South America is the Panama Canal.

Central America is the part between North and South America.

South of the Panama Canal in Latin America.

I also had this question you said back then, and I forgot how to count it specifically, but I overcame it like this at the time, hehe:

When calculating time zones, don't look at the earth as a ball, but as a map, because time zone is not a natural concept but more of a man-made concept, although it is based on time, so add east and subtract west, and it will be calculated mechanically.

I'll show you.

No more questions.

2 is the Northeast Plain, 3 is the North China Plain, and 4 is the middle and lower reaches of the Yangtze River Plain.

5 is the Qaidam Basin, 6 is the Tarim Basin, and 7 is the Junggar Basin. 10 is the Sichuan Basin.

3. The one that connects to the past is the Yellow River, and 4 the one that connects to the past is the Yangtze River.

The Pearl River is next to 11.

This problem is actually very simple, this kind of time problem should be solved by regional time, otherwise it will become very complicated, and there is no need to divide and apply time zones internationally.

The 15 degrees of longitude centered at 180 degrees are all twelve time zones, and they are consistent in time. If you are holding a clock that shows the time in the 12 time zones before crossing the date line on the right, then after you cross the date, the clock will show as many hours as you want, except that the date will be added by one day.

The above explanation, I hope to solve the landlord is your doubts......

The first question is that the heliological line is about things and things, and it is impossible to know whether you are going from east to west or from west to east.

The second problem, because the longitude is only a difference in degrees, the time difference of one degree of longitude is only a few minutes, and the degrees are almost negligible, if you go from 179 degrees west longitude to 179 degrees east longitude, it is equivalent to walking from the east side of the date line to the west side, and you should subtract one day from the date, and the time is the same.

The third question is really complicated, from the "China-Pacific-United States" half, it is true that the Japanese boundary has been crossed, but from the "China-Europe-Atlantic-United States" half, there is no matter of the Japanese boundary at all.

The time conversion is as simple as looking at the time of the area, and it does not involve the change of date at all. For example, suppose that the time difference between China and the United States is eight time zones (I forget how many it is, just an example, don't take it seriously), China is 22 o'clock on August 6, and the United States is 6 o'clock on August 7, although the date is one day apart, but the zone time is still eight hours apart, this number will not change, I don't know if you understand.

The zone time does not change, and the date is added by one day.

1. Aristotle scientifically demonstrated for the first time that the earth is a sphere based on the fact that the shadow of the moon is a circle during a lunar eclipse.

2. The ship is coming from a distance, and the mast keeps getting longer from far to near, and then you see the hull.

3. Magellan's circumnavigation of the world.

4. The formation of eclipse: The shadow of the earth is arc-shaped, so the earth is round.

"Sitting on the ground and traveling 80,000 miles a day" describes the equator, and the circumference of the equator is 40,000 kilometers, which is 80,000 miles. The Earth rotates once a day, which means 80,000 miles a day.

The continent with the least population density? - Oceania (Antarctica has no permanent population, and the seven continents are Antarctica).

The continent with the highest population density? - Asia.

Are the most tributaries of the Yellow River upstream, middle or downstream? ——The upper reaches (the source of Qinghai and the estuary of Inner Mongolia) are the most, followed by the middle reaches (the estuary of Inner Mongolia and the old Mengjin of Henan), and the lower reaches (the estuary of the old Mengjin of Henan) are the least.

There are 43 large tributaries in the upper reaches, 30 in the middle reaches, and almost no downstream (above-ground rivers). The famous tributaries have Huangshui and Tao rivers in the upper reaches, and Fen River, Wei River and Jing River in the middle reaches.

The Yangtze River - the upper reaches (the source of Qinghai, Yichang, Hubei) are the most, followed by the middle reaches (Yichang, Hubei, Jiangxi Hukou), and the lower reaches (Jiangxi Hukou estuary) are the least.

The main tributaries of the upper reaches are the Yalong River, the Min River and the Jialing River on the north bank, and the Wujiang River on the south bank. The main tributary of the middle reaches, with the Han River on the north bank; On the south bank, there are the Qingjiang River, the four rivers of Hunan, Zi, Yuan and Li of the Dongting water system and the five rivers of Jiangxi, Fu, Xin, Rao and Xiu of the Poyang water system. The main tributaries that flow into the downstream include the Qingyi River, the Shuiyang River and the Taihu Lake water system on the south bank; On the north shore there is the Chaohu Lake water system; Part of the Huai River's water also flows into the Yangtze River through the Grand Canal.

Continent with the least population density: Europe.

The continent with the highest population density: Antarctica.

The most tributaries of the Yellow River are: the most tributaries of the Yangtze River in the middle reaches are: the upper reaches.

The continent with the least population density is Antarctica;

The continent with the highest population density is Antarctica;

The tributaries in the middle reaches of the Yellow River are the most numerous;

The Yangtze River is also the most tributary in the lower reaches.

The question is this.

Ask a good question. Answer (1) As can be seen from the figure, the highest temperature in place A occurs in January, and the highest precipitation in place B occurs in August. (2) In terms of the southern and northern hemispheres, the highest temperature in place A occurs in January, which is located in the southern hemisphere; The highest temperature in the region is in July, which is located in the Northern Hemisphere. (3) The climate data of A and B are consistent with the temperate monsoon climate of B, which is consistent with the climatic characteristics of Beijing, and from the distribution of precipitation months in A and B, the rainy season is relatively concentrated in B, and the precipitation is concentrated in summer.

4) The climate of place A in the figure is characterized by hot and dry summers and mild and rainy winters, which belongs to the Mediterranean climate. The summer is hot and rainy, and the winter is cold and dry, which belongs to the temperate monsoon climate.

Hope it helps.

The smallest population is Oceania, the largest is Africa, the middle reaches of the Yellow River, and the lower reaches of the Yangtze River.

The largest in Europe and the smallest in Antarctica have the most upstream tributaries and the Yangtze River should be in the middle and lower reaches.

Minimum Antarctica.

Largest Europe.

Middle reaches of the Yellow River.

Lower reaches of the Yangtze River.

Antarctica, Europe, Upstream, Midstream.
