Cliffs of Moher (Ireland)
Located in county Clare, the Cliffs of Moher are amongst the most impressive places to see in Ireland. The cliffs consist mainly of beds of Namurian shale and sandstone, with the oldest rocks being found at the bottom of the cliffs.

Bay of Fundy(Canada)
The Bay of Fundy is renown for having the highest tides on the planet (16.2 metres or 53 feet). One hundred billion tonnes of sea water flows in and out of the Bay of Fundy twice daily – more water than the combined flow of all the world’s fresh water rivers. Fundy’s extreme tides create a dynamic and diverse marine ecosystem.
The Bay is renown for its coastal rock formations, extreme tidal effects (vertical, horizontal, rapids and bores) and sustainable coastal development. It is also a critical international feeding ground for migratory birds, a vibrant habitat for rare and endangered Right whales, one of the world’s most significant plant and animal fossil discovery regions.
The Bay of Fundy is located between the Canadian provinces of New Brunswick and Nova Scotia on North America’s east coast.
The great wall of china
The Great Wall of China, one of the greatest wonders of the world, was listed as a World Heritage by UNESCO in 1987. Just like a gigantic dragon, the Great Wall winds up and down across deserts, grasslands, mountains and plateaus, stretching approximately 8,851.8 kilometers (5,500 miles) from east to west of China. With a history of more than 2000 years, some of the sections are now in ruins or have disappeared. However, it is still one of the most appealing attractions all around the world owing to its architectural grandeur and historical significance.http://www.travelchinaguide.com/_wall/facts/
Amazon
The Amazon River Basin is home to the largest rainforest on Earth. The basin -- roughly the size of the forty-eight contiguous United States -- covers some 40% of the South American continent and includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, and Suriname, as well as French Guiana, a department of France.
Reflecting environmental conditions as well as past human influence, the Amazon is made up of a mosaic of ecosystems and vegetation types including rainforests, seasonal forests, deciduous forests, flooded forests, and savannas. The basin is drained by the Amazon River, the world's largest river in terms of discharge, and the second longest river in the world after the Nile. The river is made up of over 1,100 tributaries, 17 of which are longer than 1000 miles, and two of which (the Negro and the Madeira) are larger, in terms of volume, than the Congo (formerly the Zaire) river. The river system is the lifeline of the forest and its history plays an important part in the development of its rainforests.

Angel Fall,Venezuela

Spills from the Auyantepui into what is known as the Devil's canyon 979 Meters below. The local indians call it Kerepakupai-merú but is was named Angel Falls after Jimmy Angel, an American bush pilot and gold-hunting adventurer, who discovered it in 1937. The waters fall freely some 807 meters (2,648 feet) and reach the bottom of the valley as a misty spray that gathers into a small creek which eventually finds its way into the north-bound Churun River.
The Natives in Venezuela had known about the "Salto Angel" since the beginning of time. Then United States pilot Jimmie Angel was flying over the area in 1935 when he landed on the top of a lone mountain in search of gold. His plane got stuck in the boggy jungle on top of the mountain and he noticed a pretty impressive waterfall plunging thousands of feet down. He wasn't too happy about the 11 mile hike back to civilization, and his plane remained stuck and rusting upon the mountain as a monument to his discovery. Soon the whole world would know about the falls, which came to be known as Angel Falls, after the pilot who "discovered" them.
Angel Falls plunges from the top of a mesa, or what the natives call a Tepuyi. Named "Auyantepui", the Angel Falls mesa is one of over a hundred of its kind which are scattered about the Guiana Highlands of southeast Venezuela. Like so many slumbering giants, what characterizes these mesas (Tepuys) is their massive heights soaring up towards the sky, each with a flat top and totally vertical sides (check out the picture at left). Also called "table mountains" (which accurately describes their shapes) these Tepuys were formed out of sandstone billions of years ago. Their vertical sides are continually being eroded by the action of water from the heavy rainfall the Guiana Highlands gets. www.angel-falls.com/
Taj mahal
I guess no one in the world is unaware of this Monument of Love. This monument has found a place in the Seven Wonders of the World. Taj Mahal was built by Mughal Emperor Shah Jahan for his beloved wife Mumtaj Mahal. Thus the Monument was also named after her name. The monument was constructed by 20,000 workers and took about 16 years to complete. The white marble which was used to build Taj Mahal was brought from the quarries of Makrana, in Nagaur district of Rajasthan. Over 1000 elephants were used to transport the big rocks of white marbled used in construction. 28 kind of rare & semi precious and precious stones were used to decorate the ineer inlay of Taj Mahal. The central dome of Taj Mahal is 187 feet high at the centre. May people say that after the completion of Taj Mahal Shah Jahan ordered amputation of the hands of all the workers. So that nobody is able to construct a monument like this again on this earth.

Stonehenge, England

Stonehenge is a well-known stone monument located on a world heritage site in Salisbury Plain, Wiltshire, England. The site as is quite large and contains many other structures from the Neolithic period and the Bronze Age. Stonehenge is considered one of the most archaeologically rich sites in Europe, with many Neolithic and Bronze Age finds. It is also the site of one of the biggest Chalk grassland reversion projects in the world. Stonehenge has been occupied since around 8000BC with early work at Stonehenge beginning in 3000BC when an outer ditch and embankment was constructed, and standing timbers erected. From about 2500BC, Neolithic and Bronze age man started to bring Bluestones and Sarsen stones from Wales and the Marlborough Downs, it was completed in 1600BC. A nearby hill fort was built during the Iron Age, and there is evidence to suggest that the area was extensively settled by the Romans. The reason behind the structure still remains a mystery with many theories developed to explain the phenomenon.
Scotland

Loch Ness is the largest of three lochs located in the Great Glen which divides the North of Scotland along a line from Fort William to Inverness.
The loch is large by British standards, being 23 miles long and a mile in width, and averaging 600ft in depth. Its catchment is hilly and wet, and is drained by 6 major rivers which flow into the loch. It contains over 2 cubic miles of fresh water, and the River Ness outlet, although only 5 miles long, is one of the greatest in Britain for average flow and of course is the home of the famous monster of lore.
