Western Hemisphere

The climate varies from north to south across the Western Hemisphere due to differences in latitude, geography, and ocean currents. Generally, the northern regions are colder with more pronounced seasonal changes, while the southern regions tend to be warmer and have more moderate climates. For example, northern Canada experiences cold winters, while southern Argentina has milder winters.

Canada and Brazil are the only Western Hemisphere countries that are larger than the United States in terms of land area.

The movement of people, animals, plants, diseases, and ways of life between the Eastern Hemisphere and the Western Hemisphere is known as the Columbian Exchange. This exchange began after Christopher Columbus's voyages to the Americas in 1492 and had a significant impact on both hemispheres, leading to cultural exchange, the spread of new crops and animals, and the transmission of diseases.

The prime meridian, which is at 0 degrees longitude, is used to divide the Earth into the eastern and western hemispheres.

Some examples of things in the Western Hemisphere include North and South America, the Atlantic Ocean, the Caribbean Sea, the Rocky Mountains, and cities like Los Angeles, New York City, and Mexico City.

In North America, the Rocky Mountains and Great Plains are prominent physical features. In South America, the Andes Mountains and Amazon Rainforest stand out. In Central America and the Caribbean, volcanic activity and islands are notable features.

In the cartoon, the eastern section of the US is decided by a line of people that stretches all the way across the country, and the western section is assigned based on a game of rock-paper-scissors between two men.

-- No parts of Asia or Australia are in the western hemisphere.

-- South America is completely in the western hemisphere.

-- All of the other continents are partly in the eastern and partly in the western hemispheres.

There are thousands of rivers labeled on maps in the western hemisphere, varying in size and importance. Notable rivers include the Amazon in South America, the Mississippi in North America, and the Colorado River in the western United States.

True.

The fourth largest countries in the western hemisphere by land area are Argentina, including Greenland as part of Denmark, Brazil, and the United States.

Well, I wouldn't say it "extends". It's just that both boundary lines ... the one that separates
the northern and southern hemispheres and the one that separates the eastern and western
hemispheres ... happen to both pass through Africa, putting parts of that continent in all four hemispheres.

Sure, Africa is a good-size land-mass, but its size is not the reason that it crosses all of the
lines into all of the hemispheres. Asia is much bigger than Africa, but is almost completely
in the northern and eastern hemispheres, with only a tiny part in the southern one.

The Andes Mountains form Chile's natural eastern boundary, while the Pacific Ocean acts as its natural western boundary.

Almost but not quite all of the USA is in the western hemisphere. There is a tiny,
tiny, tiny part of Alaska that extends across the line into the eastern one.

The eastern border of the United States was still the Atlantic Ocean, but after the Louisiana Purchase in 1803, the western border wasn't well defined. We bought the place from France, and even the French weren't entirely sure what they were selling, or what we were buying. Nominally, the Louisiana Purchase included all of the land drained by the Mississippi River, so the western border should have been the Rocky Mountains and the Continental Divide.

Tools commonly used to study the land of the Western Hemisphere include satellites, aerial drones, Geographic Information Systems (GIS), and Global Positioning Systems (GPS). These technologies help researchers and geographers gather data, map terrain, and monitor changes in the landscape over time.

The Prime Meridian, located at 0 degrees longitude, divides the eastern and western hemispheres of the Earth. When standing at the Prime Meridian, countries to the east are in the Eastern Hemisphere and countries to the west are in the Western Hemisphere.

Coordinates in the northern and western hemispheres would have positive latitude and negative longitude. For example, a coordinate like 40°N, 100°W falls in the northern and western hemispheres.

There are no hemispheres without an eastern or western half. Every location on Earth lies in either the eastern hemisphere (east of the Prime Meridian) or the western hemisphere (west of the Prime Meridian).

The smallest most populous nations in the Western Hemisphere are Grenada, Saint Kitts and Nevis, and Saint Vincent and the Grenadines. These countries have small land areas but relatively high population densities compared to other nations in the region.

The northernmost country in the western hemisphere is Canada. Its northernmost point is at Ellesmere Island in the territory of Nunavut.

Most of Europe is in the Eastern Hemisphere.

The eastern and western sections of the US are divided based on the time zones. The eastern portion follows Eastern Standard Time (EST) or Eastern Daylight Time (EDT), while the western portion follows Pacific Standard Time (PST) or Pacific Daylight Time (PDT).

The Prime Meridian, which runs through Greenwich, England, is the line that divides the Earth into the Eastern and Western hemispheres. Locations to the east are in the Eastern Hemisphere, while locations to the west are in the Western Hemisphere.
