South America (West Coast)
The Himalayan mountains are caused by the convergence of the Indo-Australian and the Eurasian plates. The Himalayan mountains are fold mountains.
Hawaii is geologically a unique place on earth because it is caused by a 'hot spot'.
There are a few 'hot spots' on earth and the one under Hawaii is right in the middle of the largest crustal plates on Earth - the Pacific Plate.

The west coast of North america is a convergent boundary.
This plateau region of eastern and northern Canada and the Great Lakes area of North America mainly includes rough and rocky surfaces, and large areas of coniferous forests. A mountain range stretching from northeastern California across Oregon and Washington. Major peaks included Mt. Hood, Mt. Ranier, and Mt. St. Helens.
Mountains run along the pacific coastlines of the west coast of north america, from British Columbia running through California.
The coastal areas include bayous, deltas, marshes, mud flats and swamps.
In North America the Western Continental Divide is an imaginary line that sits atop a continuous ridge of mountain summits that divide the continent into two main drainage areas.
Rift Valley (Africa)
The Rift Valley of Africa is a convergent boundary
The African Rift valley is a place where the earth's tectonic forces are presently trying to create new plates by splitting apart old ones. A rift is like a fracture in the earths crust that widens over time.
The Western Rift Valley is also known as the Albertine Rift and features some of the highest mountain ranges in Africa. They include the Virunga Mountains, Mitumba Mountains, and Ruwenzori Range and also the Rift Valley; which contains some of the deepest lakes in the world.
There are many surrounding volcanoes of the African rift valley, such as Dallol, Gada Ale, Alu | Dalaffilla, Borale Ale, Erta Ale, Ale Bagu, Hayli Gubbi, Borawli, North Island, Central Island, South Island, The Barrier, Marsabit, Namarunu, Segererua Plateau, and many more.
Japan is a subduction zone: Volcanoes, earth quakes, and mountain building are major characteristics of the japanese islands in an active continental margin which are closely related to plate subduction.
Based on the planet's history of tectonic activity, where do you think the 'best' place to live on this planet might be?

The Kunlun is an active volcano, and the last eruption was recorded in 1951 as a central vent explosion.The Kunlun volcanlo is a Pyroclastic cone(s) volcano. Volcanic activity from this region caused a magnitude 7.2 earthquake on March 21, 2008, but no eruption was reported.he 'Great Kashmir Earthquake of 2005' that killed over 87,000 people (about 86,000 people in the Pakistan side and 1,350 in the Indian side of Kashmir), injured at least 100,000 people
Video describing convergent boundary
Iceland is a divergent boundary.
Convection currents moving in opposite directions (caused by the intense heat of the Earth's interior) in the mantle move two plates apart. As these plates move apart this leaves cracks and fissures, lines of weakness that allows magma from the mantle to escapes from the highly pressurized interior of the planet. This magma fills the gap and eventually erupts onto the surface and cools as new land.
The mountain Esja (914 m (2,999 ft)) often called Esjan ("the Esja") is situated in the south-west of Iceland, about 10 km to the north of Iceland's capital city Reykjavík. Esja is not a single mountain, but a volcanic mountain range, made from basalt and tuff-stone.
Some of the volcanoes located in Iceland are Kolbeinsey Ridge, Tjörnes Fracture Zone, Theistareykjarbunga, Krafla, Fremrinamur, Askja, Lysuhóll, Helgrindur, Ljósufjöll, Snaefellsjökull, Hofsjökull volcano, Hveravellir, Langjökull, Tungnafellsjökull, Kverkfjöll, Kerlingarfjöll, Bardarbunga, Prestahnukur, Loki-Fögrufjöll volcano, Grímsvötn, Geysir, Esjufjöll, Hengill, Hrómundartindur, Grímsnes, Grensdalur, Öraefajökull, Hekla, Torfajökull, Krísuvík, Brennisteinsfjöll, Vatnafjöll, Reykjanes, Tindfjallajökull, Katla, Eyafjallajökull, Vestmannaeyjar (Heimaey + Surtsey)
