The World's Largest Desert


he Sahara (Arabic: الصحراء الكبرىAṣ Ṣaḥrā´ al Kubrā, English: The Great Desert) is the world's second largest desert, after Antarctica. At over 9,400,000 square kilometres (3,630,000 sq mi), it covers most of Northern Africa, making it almost as large as Europe or the United States. The Sahara stretches from the Red Sea, including parts of the Mediterranean coasts, to the outskirts of the Atlantic Ocean. To the south, it is delimited by the Sahel, a belt of semi-arid tropical savanna that composes the northern region of central and western Sub-Saharan Africa.

The World's Highest Waterfall

Angel Falls (Salto Ángel) in Venezuela is the highest waterfall in the world. The falls are 3230 feet in height with an uninterrupted drop of 2647 feet. Angel Falls are located on a tributary of the Rio Caroni. The falls are formed when the tributary stream falls from the top of Auyantepui (a tepui is a flat-topped structure surrounded by cliffs - similar to a mesa).

The Deepest Part of the World Trench/ Ocean


The Mariana Trench is the deepest part of the world's oceans, and the lowest elevation of the surface of the Earth's crust. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres (1,580 mi) long but has a mean width of only 69 kilometres (43 mi). It reaches a maximum-known depth of about 10.91 kilometres (6.78 mi) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end, although some unrepeated measurements place the deepest portion at 11.03 kilometres (6.85 mi). If Mount Everest, the highest mountain on Earth at 8,848 metres (29,029 ft), was set in the deepest part of the Mariana Trench, there would be 2,076 metres (6,811 ft) of water left above it.

The Largest Forest in the World





The Amazon Rainforest (in Portuguese, Floresta Amazônica or Amazônia; Spanish Selva Amazónica, Amazonía or usually Amazonia), also known in English as Amazonia or the Amazon Jungle, is a moist broadleaf forest that covers most of the Amazon Basin of South America. This basin encompasses seven million square kilometers (1.7 billion acres), of which five and a half million square kilometers (1.4 billion acres) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, and with minor amounts in Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname and France (French Guiana). States or departments in four nations bear the name Amazonas after it. The Amazon represents over half of the planet's remaining rainforests, and it comprises the largest and most species-rich tract of tropical rainforest in the world.
