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.

Confidence votes 18.5K. The Himalayas were formed around 70 million years ago, when the Indo-Australian Plate collided with the Eurasian Plate at a convergent/destructive plate boundary.This has caused fold mountains to form as there are no subductions of the plates that can be seen from the absence of volcanoes in the Himalayas.wo different types of tectonic plate convergence were involved. The Andes are a result of subduction involving the collision of an oceanic plate and a continental plate. The â¦ Himalayas are a result of uplift and crust thickening involving the collision of two continental plates.
