How Are Volcanoes Formed? Volcanoes can be formed in several ways. They are all related to tectonic plates. The layer of the earth we live on is called the crust. It is made up of several giant chunks of crust that float on the layer below the crust, the mantle, which is liquid rock...
How are Volcanoes Formed? The earth is made up of three layers: the outer crust, the mantle, and the core. The primary ingredient for the formation of volcanoes is the mantle which is made up of molten materials and gases commonly referred to as magma. When intense pressure develops within...
How are rocks classified in the rock cycle? What is the sedimentary rock cycle? How did tectonic plates form? How are igneous rocks formed from a subduction zone? How do volcanoes support the theory of plate tectonics? What is the difference b...

So what happens to the magma formed by these processes? We saw that the magma produced at ocean ridges just hardens to form new crust material, and so doesn't produce spewing land volcanoes. There are a few continental ridge areas, where the magma does spew out onto land; but most land...

A study led by The Australian National University (ANU) has solved the 168-year-old mystery of how the world's biggest and most active volcanoes formed in Hawaii.
two Plates. As result of the fast-moving Indo-Australian Plate,the TethysOcean was completely closed in around 50 million years ago. Today, only the fossils people found on the Himalaya sedimentary rocks and the volcanoes at its edges tell us that the Himalaya area was once an ancient seabed...
Can convergent boundaries cause volcanoes? If two tectonic plates collide, they form a convergent plate boundary. ... The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. ...
