• A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak- over 2000 feet
• Generally steeper than a hill
The highest mountain on Earth is Mount Everest in
the Himalayas of Asia, whose summit is 8,850 m (29,035 ft) above mean
sea level.
The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft).
• A plateau is a flat topped highland with steep sides– Average elevation of 2000 feet
• Since it looks like a table, it is also called a tableland. They are basically areas of high flat land.
• The Tibetan Plateau or Himalayan Plateau, is a vast elevated plateau in Central Asia or East Asia.
• The Pampas, also called the Pampa, vast plains extending westward across central Argentina from the Atlantic coast to the Andean foothills.
• The deepest canyon in the world, the Indus Gorge 7,120 m (23,360 ft) deep near the Nanga Parbat mountains.
• Tsushima Strait is the eastern channel of the Korea Strait, which lies between Korea and Japan, connecting the Sea of Japan and the East China Sea.
