No, some volcanoes are underwater and when they erupt the magma gets higher and higher and forms on the ocean which is land. (that is how Hawaii was made)
The Pacific Ocean has many small scattered islands that were formed from the tips of extinct volcanoes. These types of islands are known as volcanic islands or seamounts and can be found throughout the Pacific's vast expanse.
Both shield volcanoes and stratovolcanoes can form islands.
No. They are also found above things called 'plumes'. If you want to find out more Google it, there are plenty of sites where you can get any information you might need.
Most of the Hawaiian islands were formed by volcanic activity, but not all islands currently have active volcanoes. The Big Island of Hawaii is home to active volcanoes, while some of the other islands, such as Kauai and Oahu, have dormant or extinct volcanoes.
The largest volcanoes on Earth by volume are typically found on hot spots, such as the Hawaiian Islands. Hot spots are stationary sources of volcanic activity that form large shield volcanoes over time. Tectonic spreading centers and oceanic transform faults are not typically associated with the formation of large volcanoes.
Active volcanoes are mostly found on islands such as Japan ,andaman and nicobar etc.
No. Only a handful of Hawaii's volcanoes are active.

They can occur on either. There are volcanic islands such as Hawaii and the Galapagos, but there are some found on Continents such as Mt Saint Helens. Some volcanoes can be found in the interiors of continents such as in the Great Rift Valley in Africa and one located in Yellowstone.
No. Islands are small bodies of land, whereas volcanoes have erupted to make new land.Sometimes, large volcanoes can cause new islands to emerge (like Hawaii, for example), but volcanoes and islands are two very different things.
Shield volcanoes
They are shield volcanoes
All of the Hawaiian Islands are volcanic, but only Hawaii, the Big Island, has active volcanoes at this time.

It is not so much that volcanoes tend to occur on islands as much as many islands are formed by volcanoes. Subduction zones and hot spots often cause volcanoes to develop on the sea floor. Erupted material then piles up to form islands.
