Lava solidifies to rock. New Zealand has 3 main types of volcanoes, and each has been formed from a different type of magma. Once the lava has erupted, it cools and solidifies into rock: 1  Basalt magma often forms shield volcanoes. 2  Andesite magma often forms cone volcanoes.asalt is associated with great rock columns that are found in many places around the Earth, for example, the Organ Pipes in Dunedin or the Giantâs Causeway in Ireland. Basalt magma is formed at high temperatures (around 1,200ÂºC). When it comes out of the volcano, it is hot and liquid.
Continental/Continental: The Himalayas. The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today.ontinental/Continental: The Himalayas.

Expand for References. Today I found out how the Himalayas formed. The Himalayas, which stretch some 2,900 kilometres between India, Pakistan, China, and Nepal, is the worldâs tallest mountain range.In addition to Mount Everest, the worldâs tallest mountain by peak elevation standing at 8,848 meters tall, the range also features several other mountain peaks over 8,000 meters.n part, the rate of vertical growth has varied over time, including in favor of more horizontal growth. And, of course, gravity and erosion having limited the mountainsâ growth significantly. India merging into Asia became the accepted theory about how the Himalayas were formed around 1912.
