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 force of this impact slowly pushed the land between them to fold up into big new mountains which we call the Himalayas. So at the very top of the Himalaya mountains you can find limestone that formed at the bottom of the ocean. Plate tectonics pushed the limestone up to the top of the mountain. The Himalayas are older than the Alps, but they're younger than the Rocky Mountains. A video tour of the Himalayas. The Himalayas separate India from the rest of Asia, forming the border between India and China and between India and Central Asia. The word Himalayas comes from the Sanskrit phrase home of the snow, because the Himalaya mountains are high enough to always have snow on them. They are the highest mountains in the world.
