1st - Mount Everest .

Mount Everest is regarded as the Earth's highest mountain. The first publicized height of the renowned Mount Everest was established by India's Great Trigonometric Survey. This was in the year 1856 and with an estimated height of approximately 29,002 feet or 8,840 meters.
Mount Everest is regarded as the Earth's highest mountain. It is being measured according to its summit's height above sea level. This is actually around 29,029 feet or 8,848 meters. Aside from this, Mount Everest is also indicated as a portion of the acclaimed Himalaya range along High Asia, located just within the borders of Tibet in China and Sagarmatha Zone in Nepal.
2nd - The Great Barrier Reef

Australia vacations are all about fun, adventure, and discovery, which is why The Great Barrier Reef Islands are the perfect place to visit. The Great Barrier Reef is visible from space, and is the largest coral reef system in the world, containing about 3,000 individual reefs and 900 islands that stretch for 1,616 miles over an area of 132,974 miles in the Coral Sea.
The reef system is both composed of and supported by billions of tiny organisms known as coral polyps. Much of the reef is also protected by the Great Barrier Reef Marine Park, and through these protection efforts, many of the vulnerable and endangered species that make the reef their home and are in fact endemic to the reef system are protected as well.
3rd - The Grand Canyon

Annually, hundreds of thousands of people flock to a feat of nature, the Grand Canyon, in Arizona. No one can help but marvel when they look upon the cut in the earth a mile deep, 18 miles wide, and 277 miles long.
4th - Victoria Falls

The Victoria Falls or Mosi-oa-Tunya (the Smoke that Thunders) is a waterfall situated in southern Africa on the Zambezi River between the countries of Zambia and Zimbabwe. The falls are, by some measures, the most enormous waterfall in the world, as well as being among the most unusual in form, and having arguably the most diverse and easily seen wildlife of any major waterfall site.
5th - Aurora Borealis

Auroras, sometimes called the northern and southern (polar) lights or aurorae (singular: aurora), are natural light displays in the sky, usually observed at night, particularly in the polar regions. They typically occur in the ionosphere. They are also referred to as polar auroras. In northern latitudes, the effect is known as the aurora borealis, named after the Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas by Pierre Gassendi in 1621.
Without getting too scientific there are several factors that come into play when discussing what causes the northern lights. When the sun experiences large explosions or flares there are large quantities or solar particles thrown into space. These particles form plasma clouds that usually take between two to three days to reach our earth.
