United States of America

Washington, D.C, is the capital of the United States of America. It is coextensive with the District of Columbia (the city often referred to as simply D.C.). It locates on the northern shore of the Potomac River at the river's navigation head—that is, the transshipment point between waterway and land transport. The state of Maryland borders the District of Columbia to the north, east, and west and the state of Virginia borders the District on the southern shore of the Potomac River. Washington is an extraordinary city with multiple personalities: a working federal city, an international metropolis, a picturesque tourist destination, an unmatched treasury of the country's history and artifacts, and a cosmopolitan center that retains a neighborly small-town ambiance. Washington's role as the capital of the United States often overshadows its lively local history and its complex political, economic, and social issues. About half the land in Washington is owned by the U.S. government, paying no taxes. Several hundred thousand people in the D.C. metropolitan area work for the federal government. Washington has a temperate climate with high humidity levels. Precipitation throughout the year evenly distributes, averaging between 3 and 4 inches (75 and 100 mm) per month. Much of the attractiveness of Washington can be attributed to the hundreds of outdoor sculptures and monuments that adorn the parks, gardens, buildings, avenues, and cemeteries of the city. L'Enfant suggested using outdoor sculpture to honor the new country's heroes. The first outdoor sculpture situated in Washington was the Tripoli Memorial, commemorating the heroes of the Tripolitan War (1801–05). It stood first in the Navy Yard in Southeast Washington and later moved to the Capitol grounds before being relocated to the Naval Academy in Annapolis, Maryland.

The climate of the United States varies due to changes in latitude, and a range of geographic features, including mountains and deserts. Generally, on the mainland, the climate of the U.S. becomes warmer the further south one travels and drier the further west until one reaches the West Coast.

English is the most spoken language in the United States.

1. America is home to many natural wonders of the world. In fact, the United Nations Education, Scientific. Cultural Organization (UNESCO) have recognized many heritage sites in America. According to UNESCO, a world heritage site is a place of special cultural or physical significance.
2. The Missouri River is the longest in North America. The river derives from Montana, located at the base of the Rocky Mountains. It flows for approximately 2 341 miles (3 767 kilometers) before emptying into the Mississippi River just north of St. Louis, Missouri. The Missouri River and the Mississippi River combine to create the 4th most comprehensive river system globally.
3. The United States has maintained its position as the world’s largest economy since 1871. The economy is so large that the US is often noted as an economic superpower because it makes up almost a quarter of the global economy.
4. The first American Flag only displayed 13 stripes and 13 stars arranged in a circle. The stars and stripes represented the 13 colonies that declared independence from Great Britain. While the origins of the first American Flag are unknown, some do believe that it was designed by a New Jersey Congressman, Francis Hopkinson, and sewn by a Philadelphia seamstress, Betsy Ross.
5. The Gateway Arch, also known as the "Gateway to the  West," is a monument in St. Louis, Missouri, and sits along the west bank of the Mississippi River. At 630 feet tall, the Gateway Arch claims the title of the tallest artificial monument in the US. The memorial commemorates the United States' westward expansion and is officially dedicated to "the American People." The Arch is internationally recognized as a symbol of St. Louis, and because of this, it is a popular tourist destination.
   

• Every year, on February 2, Americans will discover if a Pennsylvanian groundhog named Punxsutawney Phil has seen his shadow. The tradition, which dates from the 18th-century says, if Punxsutawney Phil emerges from its burrow and sees its shadow, it will get a fright and scurry back underground. 
• Sticking with the animal traditions, the US president is presented with a Thanksgiving turkey at a special ceremony each Thanksgiving. The president then pardons the turkey (for what crime we do not know), and the turkey is spared from becoming the star of the dinner table. The happy turkey then returns to the farm to live out the rest of its days. This American tradition dates back to Abraham Lincoln, but it wasn’t until 1989 that the pardoning of the turkey became a permanent part of the ceremony.
• On the 4th of July, 1776, the Declaration of Independence adopters and the 13 American colonies severed their political ties with Great Britain. The following year marked the date with grand celebrations, including fireworks. The tradition has continued ever since. However, it only made the 4th of July a federal holiday in 1941. Nowadays, America’s birthday celebrates with parades, cookouts, concerts, and fireworks.
• Tucking into a Thanksgiving feast is one of the oldest traditions in America. It dates back to 1621, when the English colonists (Pilgrims) of Plymouth and the Wampanoag people shared an autumn harvest meal. However, Thanksgiving wasn’t declared a national holiday until 1863. It is celebrated on the fourth Thursday of November each year, and Thanksgiving Day commemorates the harvest and other blessings of the past year. The feast features traditional foods like stuffing, mashed potatoes, cranberry sauce, pumpkin pie, and a turkey. People usually share the bountiful meal with family and friends.
