Volcanoes usually form near plate boundaries where subduction is occurring. This causes magma from the mantle to rise up onto Earth's surface and form volcanoes. Most volcanoes are formed in this way. Volcanoes can also be formed by hotspots. Magma from the mantle rises through these hotspots and find their way to Earth's surface, forming volcanoes in a chain like Hawaii.
Well, volcanoes are usually the land that creates islands like Hawaii. I'm doing homework right now and i'd say an island? If not that, i'd go with the first two answers. :)
they form by something
composite volcanos
igneous rock

Jupiter, being one of the gas giants within our solar system is not believed to have a rocky surface. If volcanos were to exist on Jupiter, they would not be in a similar form to what is observed on Earth.
Jessie they formed all of land over water we see today.
