4. Scientists believe that 40,000 basaltic columns of this structure formed in northern Ireland about 50 million years ago. This happened when lava- flow cracked vertically along regular geometric angles as it slowly cooled.

9. It is the world’s largest desert found in Northern Africa. Areas of vegetation are now limited to oasis fed by underground springs. It is about 11,00 to 12,00 km wide and 4800 km long from east to west. ------------------

10. This place in South America is the world’s largest of its kind. It has a diverse collection of plants and animal species on the earth and is home to large varieties of world’s plants, birds, and insect species. -------------------

11. The largest cave system on earth, it stretches 640 km underneath a limestone ridge in South Central Kentucky (USA) hollowed out by trickling water for the past 10 millions years. The cave has unusual shapes and rare creatures. -------------------

12. The world’s coldest, iciest region containing most of the world’s fresh water. This glacial desert has been the site of the lowest recorded temperature (-89.2°C) on average It is 1.2 km thick and provides home to seals, and whales and penguins. -----------------
