lava rock
They can form islands: when hot lava reaches the ocean, it will harden and form an island.
Volcanoes that form along a mid-ocean ridge are called volcanic islands. These volcanoes occur when the plates move apart to produce gaps which molten lava rises to fill.
The lava that comes out of the volcano will go hard after it hits water. It will eventually build up and form an island.
Lava
When Volcanoes erupt the surface is melted by the lava
Most shield volcanoes have grown from the ocean floor to form broad, gently sloping structures with low viscosity lava flows. They are typically formed by multiple eruptions of basaltic lava, which flows easily and spreads out over a wide area, resulting in the characteristic shield shape.
Shield volcanoes form extensive fluid lava flow that erupts numerous times.
Because the lava from volcanoes form igneous rocks
No, volcanoes do not need lava to be volcanoes.

NO, volcanoes make lava.
Lava cools down and accumulates into rock as it reaches Earth's surface
