The difference between east west longitude and east west hemisphere

And give you a part of the content, if I can help you, I teach junior high school geography.

6.Division of the Eastern and Western Hemispheres: Internationally Customary.

The two hemispheres separated by the coil of 20°W and 160°E are called the eastern hemisphere and the western hemisphere respectively.

From the longitude range: 20°W east across 00 meridian to 160°E in the Eastern Hemisphere; 20°W westward across the 180° degree meridian to 160°E in the Western Hemisphere.

From the perspective of longitude: east longitude less than 160°E and west longitude less than 20°w are in the eastern hemisphere; Contrary to in the Western Hemisphere.

160°E and 20°W belong to neither the Eastern nor the Western Hemisphere.

East-West Longitude: East Longitude: East to 180° from 0° meridian West Longitude: West to 180° from 0° meridian

Eastern and Western Hemispheres: Eastern Hemisphere: 20° west longitude east to 160° east longitude, i.e. 20° w-0°--160°E is the eastern hemisphere.

Western Hemisphere: 160°E to 20°W longitude, i.e. 160°E--180°-20°W is the Western Hemisphere.

They are divided differently.

The east-west meridian is divided by the prime meridian, the 0 degree line, which runs through the Greenwich Observatory in London. The east and west longitudes are 180 degrees each.

The eastern and western hemispheres are divided by a meridian coil composed of 20 degrees west longitude and 160 degrees east longitude. Why not use a 0 degree warp and a 180 degree warp? Because these two meridians pass through some countries and divide one country into two hemispheres, the other two on the sea were chosen.

The longitude range of the Eastern Hemisphere is east of 20°W longitude on the earth, and 160°E longitude is west (20°W-160°E). The range of longitude in the Western Hemisphere is 20°W and 160°E (20°W-160°E) on Earth.

The Eastern Hemisphere is the area of the Earth east of 20° West longitude and west of 160° early longitude (20°W-160°E). According to this division, the land mass of the Eastern Hemisphere consists of most of Asia, the eastern part of Antarctica, the vast majority of Europe, the vast majority of Africa, a small part of northeastern North America, most of Oceania, and many other islands. Oceans include the western Pacific Ocean, the eastern Atlantic Ocean, and the Indian Ocean.

The Western Hemisphere is the region of the Earth west of 20°W longitude and 160°E east (20°W-160°E). The region has a small land area and a vast ocean area, mainly including North and South America, the eastern Pacific Ocean, part of the Atlantic Ocean, part of the Arctic Ocean and part of Antarctica.

What is the eastern and western hemisphere longitude range? There are 180 degrees in east and west.

The dividing line between east and west longitude is the prime meridian.

0 degrees of longitude), east is east longitude, west is west longitude (east longitude increases to the east, west longitude increases to the west).

East longitude is positive, west longitude is negative. Longitude is the degree in which a point on Earth is east or west of a north-south alignment line called the prime meridian.

The longitude of the prime meridian is 0°, and the longitude of the rest of the earth is 180° east or 180° west. Unlike latitude, which has an equator as a natural starting point, longitude has no natural starting point, and the line that is the prime meridian is chosen by the people.

From the 0° meridian to the east to the west, it is divided into 180°.

The east longitude is characterized by being larger the further east, and the west longitude is characterized by the larger the westerly longitude. The longitude of the Americas is west, and most of the longitude in Asia, Europe, Africa, and the Australian continent is east.

Eastern and Western Hemispheres: Bounded by the longitude coil at 20 degrees west longitude and 160 degrees east longitude - east of 20 degrees west longitude, west of 160 degrees east longitude is the eastern hemisphere; West of 20 degrees west longitude and east of 160 degrees east longitude is the Western Hemisphere.

Northern and Southern Hemispheres: Bounded by the equator (0 degrees of parallel) – north of the equator is the Northern Hemisphere, south of the Southern Hemisphere.

Longitude and latitude is the combined name of longitude and latitude to form a coordinate system, called the geographic coordinate system, which is a spherical coordinate system that uses the spherical surface of three-dimensional space to define the space on the earth, and can mark any position on the earth.

The parallel, like the meridian, is an auxiliary line assumed by humans 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.

From the equator to the north and south, each 90°, is called the north and south latitudes, which are denoted by "n" and "s", respectively.

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）

The length is different (the farther away from the equator, the shorter the parallel).

The range of longitude in the Western Hemisphere is: 160 degrees east longitude to 20 degrees west longitude (or 20 degrees west to 160 degrees east longitude), that is, 160 degrees east longitude, 180 degrees east longitude, and 20 degrees west longitude.

The longitude range of the Eastern Hemisphere is: 20 degrees west longitude east to 160 degrees east longitude (or 160 degrees east longitude west to 20 degrees west longitude), that is, east longitude 20 degrees west longitude 0 degrees 160 degrees.

Eastern Hemisphere Region:

The Eastern Hemisphere consists of most of Asia, the eastern part of Antarctica, most of Europe, most of Africa, a small part of northeastern North America and most of Oceania, as well as many other islands. Oceans include the western Pacific Ocean, the eastern Atlantic Ocean, and the Indian Ocean.

Western Hemisphere Countries:

South America: Colombia, Venezuela, Guyana, Suriname, Ecuador, Peru, Brazil, Bolivia, Chile, Paraguay, Uruguay, Argentina 12 independent countries and 2 regions of French Guiana and Malvinas Islands (Falkland Islands).

North America: Bahamas, Belize, United States, Barbados, Canada, Costa Rica, Cuba, El Salvador, Grenada, Guatemala, Honduras, Haiti, Jamaica, Saint Lucia, Mexico, Nicaragua, Panama, Dominica, Dominica, Saint Vincent and the Grenadines, Trinidad and Tobago, Antigua and Barbuda, Saint Kitts and Nevis, Puerto Rico, Netherlands Antilles. Largest cities:

New York's largest city in the southern hemisphere: São Paulo.

The hemisphere of the Earth located east of 20 degrees west longitude and west of 160 degrees east longitude is called the Eastern Hemisphere, and the rest of the Earth is called the Western Hemisphere.

The meridian in the middle of the Western Hemisphere is the 110 degrees west longitude. The distance from 160 degrees east longitude and 20 degrees west longitude is 90 degrees longitude difference.

Longitude, a geographical term, generally refers to the ordinate of a spherical coordinate system, specifically the degree to the east or west of a north-south alignment of a place on Earth called the prime meridian. According to international regulations, the longitude at the original site of the Greenwich Observatory in London, the capital of the United Kingdom, is set at 0° longitude, and then extends to the left and right. The time zones are also divided into regions, with a difference of one hour every 15 degrees of longitude.

Longitude, as a basis of the theory of earth laughter, is the basic theory for understanding the rotation of the earth and the division of the conjecture of the region.

If it is the Northern Hemisphere, according to the direction of the Earth's rotation is counterclockwise, near the first meridian of the Blind Simplified Preparation, because it is from west to east, it can be judged that the east and west have been worn out. If it is a southern sock hemisphere, it is clockwise according to the direction of the Earth's rotation. Similarly, the east-west meridian can be determined near the prime meridian.

The east-west longitude is divided by a meridian coil composed of a 0-degree meridian (prime meridian) and a 180-degree meridian: east of the 0-degree meridian and east longitude to the west of the 180-degree meridian; Conversely, the west of the 0 degree meridian and the east of the 180 degree meridian are the west longitude.

The eastern and western hemispheres are divided by a meridian coil composed of 20 degrees west longitude and 160 degrees east longitude: east of the 20 degrees west longitude, the hemisphere west of the 160 degrees east longitude is the eastern hemisphere; Conversely, the western hemisphere is west of the 20th longitude and 160 degrees east of the 160th longitude.

Eastern and Western Hemispheres - East longitude means the eastern hemisphere, and west longitude means the western hemisphere.

Northern and Southern Hemispheres - Southern latitude represents the Southern Hemisphere, and northern latitude represents the Northern Hemisphere.

To find the dimensions on the map, first find the location of the meridian (also the location of the meridian at 0 degrees). Generally, it is in the middle of the map (in the Pacific Ocean to the east of China), and then according to the geographical coordinates - up the north, down the south, left west, right east on the map according to the longitude and latitude lines, count the number of degrees is how many degrees.

The 0 degree meridian to the east to the 180 degrees east longitude is the range of east longitude, and the 0 degree meridian west to the west longitude 180 degrees west longitude is the range of west longitude. 20 degrees west longitude east to 160 degrees east longitude is the Eastern Hemisphere, and 20 degrees west longitude to 160 degrees east longitude is the Western Hemisphere.
