Toronto, Canada

Toronto is the most populous city in Canada and the provincial capital of Ontario. It is located in Southern Ontario on the northwestern shore of Lake Ontario. The history of Toronto began in the late 18th century when the British Crown purchased its land from the Mississaugas of the New Credit. The British established a settlement there, called the Town of York, which its lieutenant governor, John Graves Simcoe, designated as the capital of Upper Canada. The city was ransacked in the Battle of York during the War of 1812. In 1834, York was incorporated as a city and renamed Toronto. It was damaged in two huge fires in 1849 and 1904. Over the years, Toronto has expanded its borders several times through amalgamation with surrounding municipalities, most recently in 1998. According to the 2011 Census, the city has 2.6 million residents, making it the fifth-most populous city in North America. In 2012, the municipal government published a population estimate of 2,791,140, which led to media reports claiming Toronto as the fourth most populous city in North America and the most populous Great Lakes city, surpassing Chicago. The census metropolitan area (CMA) had a population of 5,583,064,[4] and the Greater Toronto Area (GTA) had a population of 6,054,191 in the 2011 Census. Toronto is at the heart of the Greater Toronto Area, and of the densely populated region in Southern Ontario known as the Golden Horseshoe. Its cosmopolitan and international population reflects its role as an important destination for immigrants to Canada. Toronto is one of the world's most diverse cities by percentage of non-native-born residents, with about 49% of the population born outside Canada. As Canada's commercial capital, it is home to the Toronto Stock Exchange and the five largest banks in the nation. Toronto will host the 2015 Pan American Games.

Lake Geneva, France

Lake Geneva or Lake Léman (French: Lac Léman, Le Léman, sometimes Lac de Genève, German: Genfersee) is a lake in Switzerland and France. It is one of the largest lakes in Western Europe. 59.53% 345.31 km2 (133.32 sq mi) of it comes under the jurisdiction of Switzerland (cantons of Vaud, Geneva, and Valais), and 40.47% 234.71 km2 (90.62 sq mi) under France (Haute-Savoie).
Lake Geneva is divided into three parts because of its different reasons of formation (sedimentation, tectonic folding, glacial erosion):
Haut Lac (Upper Lake), the eastern part from the Rhone estuary to the line of Meillerie–Rivaz
Grand Lac (Large Lake), the largest and deepest basin with the lake's largest width
Petit Lac (Small Lake), the most south-west, narrower and less deep part from Yvoire–Promenthoux next Prangins to the exit in Geneva
According to the Swiss Federal Office of Topography, swisstopo, Lac de Genève designates that part of the Petit Lac, which lies within the cantonal borders of Geneva (excluding the cantonal exclave Céligny), so about from Versoix–Hermance to the Rhone outflow in Geneva.
The Chablais Alps border is its southern shore, the western Bernese Alps lie over its eastern side. The high summits of Grand Combin and Mont Blanc are visible from some places. Compagnie Générale de Navigation sur le lac Léman (CGN) operates boats on the lake.
The lake lies on the course of the Rhone. The river has its source at the Rhone Glacier near the Grimsel Pass to the east of the lake and flows down through the Canton of Valais, entering the lake between Villeneuve and Le Bouveret, before flowing slowly towards its egress at Geneva. Other tributaries are La Dranse, L'Aubonne, La Morges, La Venoge, La Vuachère, and La Veveyse. Lake Geneva is the largest body of water in Switzerland, and greatly exceeds in size all others that are connected with the main valleys of the Alps. It is in the shape of a crescent, with the horns pointing south, the northern shore being 95 km (59 mi), the southern shore 72 km (45 mi) in length. The crescent form was more regular in a recent geological period, when the lake extended to Bex, about 18 km (11 mi) south of Villeneuve. The detritus of the Rhone has filled up this portion of the bed of the lake, and it appears that within the historical period the waters extended about 2 km (1.2 mi) beyond the present eastern margin of the lake. The greatest depth of the lake, in the broad portion between Évian-les-Bains and Lausanne, where it is just 13 km (8.1 mi) in width, has been measured as 310 m (1,020 ft), putting the bottom of the lake at 62 m (203 ft) above sea level. The lake's surface is the lowest point of the cantons of Valais and Vaud. The beauty of the shores of the lake and of the sites of many of the places near its banks has long been celebrated. However it is only from the eastern end of the lake, between Vevey and Villeneuve, that the scenery assumes an Alpine character. On the south side the mountains of Savoy and Valais are for the most part rugged and sombre, while those of the northern shore fall in gentle vine-covered slopes, thickly set with villages and castles.

Lake Garda, Italy:

Lake Garda (Italian: Lago di Garda or Lago Benaco) is the largest lake in Italy. It is a popular holiday location and is located in Northern Italy, about half-way between Brescia and Verona, and between Venice and Milan. Glaciers formed this alpine region at the end of the last Ice Age. The lake and its shoreline are divided between the provinces of Verona (to the south-east), Brescia (south-west), and Trentino (north).
The northern part of the lake is narrower, surrounded by mountains, the majority of which belong to the Gruppo del Baldo. The phallic shape is typical of a moraine valley, probably having been formed under the action of a Paleolithic glacier. Although traces of the glacier's actions are evident today, in more recent years it has been hypothesised that the glacier occupied a previously existing depression, created by stream erosion 5 to 6 million years ago.
The lake has numerous small islands and five main ones, the largest being Isola del Garda. Nearby to the south is Isola San Biagio, also known as the Isola dei Conigli ("Island of the Rabbits"). Both are offshore of San Felice del Benaco, on the west side. The three other main islands are Isola dell'Olivo, Isola di Sogno, and Isola di Trimelone, all farther north near the east side. The main tributary is the Sarca River, while the only outlet is the Mincio River.
If the water level of the Adige river is too high, excess water is diverted to the lake through the Mori-Torbole tunnel.

Moon

The Moon is the only natural satellite of the Earth and the fifth largest moon in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary,[e] having 27% the diameter and 60% the density of Earth, resulting in 1⁄81 its mass. Among satellites with known densities, the Moon is the second densest, after Io, a satellite of Jupiter.

The Moon is in synchronous rotation with Earth, always showing the same face with its near side marked by dark volcanic maria that fill between the bright ancient crustal highlands and the prominent impact craters. It is the brightest object in the sky after the Sun, although its surface is actually dark, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its regular cycle of phases have, since ancient times, made the Moon an important cultural influence on language, calendars, art and mythology. The Moon's gravitational influence produces the ocean tides and the minute lengthening of the day. The Moon's current orbital distance, about thirty times the diameter of the Earth, causes it to appear almost the same size in the sky as the Sun, allowing it to cover the Sun nearly precisely in total solar eclipses. This matching of apparent visual size is a coincidence. The Moon's linear distance from the Earth is currently increasing at a rate of 3.82±0.07 cm per year, but this rate is not constant.[8]

The Moon is thought to have formed nearly 4.5 billion years ago, not long after the Earth. Although there have been several hypotheses for its origin in the past, the current most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body.

The Moon is the only celestial body other than Earth on which humans have set foot. The Soviet Union's Luna programme was the first to reach the Moon with unmanned spacecraft in 1959; the United States' NASA Apollo program achieved the only manned missions to date, beginning with the first manned lunar orbiting mission by Apollo 8 in 1968, and six manned lunar landings between 1969 and 1972, with the first being Apollo 11. These missions returned over 380 kg of lunar rocks, which have been used to develop a geological understanding of the Moon's origins, the formation of its internal structure, and its subsequent history.

After the Apollo 17 mission in 1972, the Moon has been visited only by unmanned spacecraft. Of these, orbital missions have dominated: Since 2004, Japan, China, India, the United States, and the European Space Agency have each sent lunar orbiters, which have contributed to confirming the discovery of lunar water ice in permanently shadowed craters at the poles and bound into the lunar regolith. The post-Apollo era has also seen two rover missions: the final Soviet Lunokhod mission in 1973, and China's ongoing Chang'e 3 mission, which deployed its Yutu rover on 14 December 2013.

Future manned missions to the Moon have been planned, including government as well as privately funded efforts. The Moon remains, under the Outer Space Treaty, free to all nations to explore for peaceful purposes.
