Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres.

A common way of referring to regions in the United States is grouping them into 5 regions according to their geographic position on the continent: the Northeast, Southwest, West, Southeast, and Midwest.

Geographic regions are divided by variations in landforms, climate, and natural resources. Regions vary with regard to development of natural resources, art, architecture, literature, customs, religion, economics, and transportation. The characteristics of a region can change.

Three common types of regions are formal regions, which are defined formally by government or other structures, such as cities, states, and mountain ranges; functional regions, which consist of a central place and the surrounding areas that are dependent upon that place, such as a metropolitan area; and vernacular …

A region is a basic unit of geographic study. It is defined as an area that has unifying characteristics. For example, the peaks and valleys of the Rocky Mountains form a physical region. Some regions are distinguished by human characteristics.

Regions can include large areas of a country such as the American Midwest, the British Midlands, the Swiss Alps, the south east of England and southern California; or smaller areas such as Silicon Valley in northern California.

Ten Smallest States

The 5 Smallest States by Land Area

• Rhode Island—1,045 square miles (2,707 square kilometers)
• Delaware—1,954 square miles (5,061 square kilometers)
• Connecticut—4,845 square miles (12,548 square kilometers)
• Hawaii—6,423 square miles (16,635 square kilometers)

Rhode Island is the smallest state in the US with a total area of just 1,544.89 square miles.

1. Rhode Island. Rhode Island might be small, but it holds a great deal of American history.
2. Delaware.
3. Connecticut.
4. New Jersey.
5. New Hampshire.

Here is a list of the top ten least populated states in the country:

• Wyoming (Population: 581,075)
• Vermont (Population: 623,251)
• District of Columbia (Population: 714,153)
• Alaska (Population: 724,357)
• North Dakota (Population: 770,026)
• South Dakota (Population: 896,581)
• Delaware (Population: 990,334)

Alaska is still a massive state But when you look at most two dimensional maps, Alaska actually looks much larger than that. In the case of many map projections, Alaska appears to be more than half the size of the lower 48 states, when in reality the continental US is 4.7 times as large.

Is Alaska Bigger Than Europe? The total area of Europe is 3,837,081 square miles, while the state of Alaska comprises 663,268 total square miles. This equals about 1/6 of the size of Europe. So no, it’s not nearly as large as Europe.

United States is about 1.3 times bigger than Australia. Australia is approximately 7,741,220 sq km, while United States is approximately 9,833,517 sq km, making United States 27% larger than Australia.

By this measure, Australia comes out on top, with median wealth of $US191,453 ($263,822) per adult. The US has a median wealth of $US61,667 ($84,977) per adult, which puts the country at number 18, well behind others, including the UK ($US97,169), Canada ($U106,342), and New Zealand ($US98,613).

Canada is around the same size as Australia. Australia is approximately 7,741,220 sq km, while Canada is approximately 9,984,670 sq km.

Based on landmass, Vatican City is the smallest country in the world, measuring just 0.2 square miles, almost 120 times smaller than the island of Manhattan. Situated on the western bank of the Tiber River, Vatican City’s 2-mile border is landlocked by Italy.
