The USA Today Wonders of the World
Potala Palace
The Potala Palace (Tibetan: ཕོ་བྲང་པོ་ཏ་ལ་, Wylie: pho brang Potala) in Lhasa, Tibet Autonomous Region, China was the residence of the Dalai Lama until the 14th Dalai Lama fled to India during the 1959 Tibetan uprising. It is now a museum and World Heritage Site.
The palace is named after Mount Potalaka, the mythical abode of the bodhisattva Avalokiteśvara. The 5th Dalai Lama started its construction in 1645 after one of his spiritual advisers, Konchog Chophel (died 1646), pointed out that the site was ideal as a seat of government, situated as it is between Drepung and Sera monasteries and the old city of Lhasa. It may overlay the remains of an earlier fortress called the White or Red Palace on the site, built by Songtsen Gampo in 637.
Old City of Jerusalem
The Old City (Hebrew: הָעִיר הָעַתִּיקָה, Ha'Ir Ha'Atiqah, Arabic: البلدة القديمة, al-Balda al-Qadimah) is a 0.9 square kilometers (0.35 sq mi) walled area within the modern city of Jerusalem.
Until 1860, when the Jewish neighborhood Mishkenot Sha'ananim was established, this area constituted the entire city of Jerusalem.
The Old City is home to several sites of key religious importance: the Temple Mount and Western Wall for Jews, the Church of the Holy Sepulchre for Christians and the Dome of the Rock and al-Aqsa Mosque for Muslims. It was added to the UNESCO World Heritage Site List in 1981.
Polar Ice Caps
A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice.
There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land; only that it must be a body of solid phase matter in the polar region. This causes the term "polar ice cap" to be something of a misnomer, as the term ice cap itself is applied more narrowly to bodies that are over land, and cover less than 50,000 km2: larger bodies are referred to as ice sheets.
Earth's polar caps have changed dramatically over the last 12,000 years. Seasonal variations of the ice caps takes place due to varied solar energy absorption as the planet or moon revolves around the Sun. Additionally, in geologic time scales, the ice caps may grow or shrink due to climate variation.
Papahānaumokuākea Marine National Monument
The Papahānaumokuākea Marine National Monument (roughly /pɑːpɑːˈhɑːnaʊmoʊkuˌɑːkeɪ.ə/) is a World Heritage listed U.S. National Monument encompassing 583,000 square miles (1,510,000 km2) of ocean waters, including ten islands and atolls of the Northwestern Hawaiian Islands. Created in June 2006 with 140,000 square miles (360,000 km2), it was expanded in August 2016 by moving its border to the limit of the exclusive economic zone, making it one of the world's largest protected areas. It is internationally known for its cultural and natural values as follows:
"The area has deep cosmological and traditional significance for living Native Hawaiian culture, as an ancestral environment, as an embodiment of the Hawaiian concept of kinship between people and the natural world, and as the place where it is believed that life originates and to where the spirits return after death. On two of the islands, Nihoa and Makumanamana, there are archaeological remains relating to pre-European settlement and use. Much of the monument is made up of pelagic and deepwater habitats, with notable features such as seamounts and submerged banks, extensive coral reefs and lagoons."
Internet
The Internet (contraction of interconnected network) is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
The origins of the Internet date back to research commissioned by the federal government of the United States in the 1960s to build robust, fault-tolerant communication with computer networks. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia since the 1980s, commercialization incorporated its services and technologies into virtually every aspect of modern life.
Mayan Ruins
The peoples and cultures which comprised the Maya civilization spanned more than 2,500 years of Mesoamerican history, in the region of southern Mesoamerica which incorporates the present-day nations of Guatemala and Belize, much of Honduras and El Salvador, and the southeastern states of Mexico from the Isthmus of Tehuantepec eastwards, including the entire Yucatán Peninsula.
Throughout this region, many hundreds of Maya sites have been documented in at least some form by archaeological surveys and investigations, while the numbers of smaller/uninvestigated (or unknown) sites are so numerous (one study has documented over 4,400 Maya sites) that no complete archaeological list has yet been made. The listing which appears here is necessarily incomplete, however it contains notable sites drawn from several large and ongoing surveys, such as the Corpus of Maya Hieroglyphic Inscriptions (CMHI) and other sources (see References).
Great Migration of Serengeti and Masai Mara
The Serengeti (/ˌsɛrənˈɡɛti/) ecosystem is a geographical region in Africa. It is located in northern Tanzania. It spans approximately 30,000 km2 (12,000 sq mi).
The Serengeti hosts the second largest terrestrial mammal migration in the world, which helps secure it as one of the Seven Natural Wonders of Africa, and as one of the ten natural travel wonders of the world. The Serengeti is also renowned for its large lion population and is one of the best places to observe prides in their natural environment. The region contains the Serengeti National Park in Tanzania and several game reserves.
Approximately 70 large mammal and 500 bird species are found there. This high diversity is a function of diverse habitats, including riverine forests, swamps, kopjes, grasslands, and woodlands. Blue wildebeests, gazelles, zebras, and buffalos are some of the commonly found large mammals in the region.
