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.

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.

The India tectonic plate moving north at about 45mm a year is pushing under the Eurasian plate beneath the Himalayas. | Humanitarian crises, Asia, Nepal, Earthquake.Two tectonic plates meet beneath the Himalayas along a fault line. The India plate is moving north at around 45mm a year and pushing under the Eurasian plate. Over time that is how the Himalayas were created.Dr Brian Baptie, head of seismology at the British Geological Survey in Edinburgh, explains the potential after-effects of the quake.he India plate is moving north at around 45mm a year and pushing under the Eurasian plate.
