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.

Which mountains were formed by the collision between continents? Numerous mountain ranges were formed by the collision of two continental tectonic plates, including the Himalayas, the Alps, the Appalachians and the Atlas mountains. It is also thought that the Rocky Mountains formed in part due to small pieces of land on the Pacific oceanic plate colliding with North America.
