STRUCTURAL LANDFORMS

e.g. Mountains, Fault, Scarps, Valleys, etc.

WEATHERING LANDFORMS

e.g. Soils, Karst Caves, talus cones etc.

EROSIONAL LANDFORMS

e.g. Rivers and Glacial, Valleys, Gullies etc.

DEPOSITIONAL LANDFORMS

e.g. Sand Bars, Alluvial Fans, Deltas,

Floodplains, Glacial till, etc.

Mountains

• 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).

Plateaus

• 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.

Plains

• Usually smooth or slightly rolling– less than 500 feet

• 55% of earth’s land surface is plains

• The Pampas, also called the Pampa, vast plains extending westward across central Argentina from the Atlantic coast to the Andean foothills.

Hills

• Over 500 feet but less than 2000 feet• Habitability less than plains, greater than

mountains

• Signal Hill or Lion's Rump, is a landmark flat-topped hill located in Cape Town

Bay

• A small body of water enclosed partially by land.

• Wineglass Bay is located on the island of Tasmania , Australia

Canyon

A valley that is deep and has

steep sides

• The deepest canyon in the world, the Indus Gorge 7,120 m (23,360 ft) deep near the Nanga Parbat mountains.

Strait

• A narrow waterway connecting two larger bodies of water

• 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.
