Dry lava builds up and over time it grows to be above the water and that's how volcanic islands are made.

What is released from a volcanic island?
Magma, (Volcanic Rock)
What is an area of volcanic activity that develops above rising plumes of magma?
Areas of volcanic activity that develop above rising plumes of magma are called hot spots.
How does magma that hardens beneath the surface create land forms?
It creates it because when a volcano erupts, it releases lave and magma which will eventually cool, dry and harden, which creates a volcanic island.
What does magma rising between separate plates create?
Stuff
How does rising magma and flowing lava create volcanic islands?
When lava erupts, it cools and hardens. After long periods of this happening and cooling in layers on top of all the other cooled lava, a mountain of hardened lava rises out of the water and to the surface. This rising mountain soon will become a volcanic island.

True or false many volcanoes are found in island arcs?
True. Island arcs are formed due to the subduction of one tectonic plate beneath another, creating a line of volcanic islands. The volcanic activity in these regions is a result of magma rising to the surface from the subducted plate, leading to the formation of numerous volcanoes.

How did the santorini volcano form?
Santorini volcano was formed by the conversion of the African plate and the Aegean Sea Plate. As subduction occurred, some magma burned to the surface and create volcanic islands called island arcs. Santorini is one of those volcanic islands.

Can you swim under Hawaii?
the answer is no, because it is a volcanic island. which ,means it was created by the magma and the earth plates shifting.
What was the Hawaiin island formed out of?
The Hawaiian Islands were formed by volcanic activity millions of years ago. The islands formed as a result of magma rising up from the Earth's mantle through a hotspot beneath the Pacific tectonic plate. Over time, repeated volcanic eruptions built up the islands we see today.
What does a volcanic island form over?
A volcanic island realy doesn't form over anything. Hot magma rises from benieth the sea and cools. Sometimes it doesn't make it to the surface and it flows down to the bottom again.
Why does a volcanic island suddenly explode?
Not all volcanic islands are explosive. Many volcanic islands form at subduction zones, where an oceanic plate slides into the mantle. Such areas tend to produces viscous magma with water trapped in it. In an island setting, additional seawater often seeps into the volcano. As the magma approaches the surface and pressure drops, the water is explosively released as steam (other gasses are relased as well). This process stakes magma with it, forming ash and pumice.
