Volcanic Neck

When magma hardens in a volcano's pipe, the result will eventually be a volcanic neck or volcanic plug. This landform is a solidified remnant of magma that once filled the volcano's vent.
When a volcano erupts and the lava hardens it can build up under water and over time, if enough builds up, the result will be an island
They are formed in a very different way. Unlike usually Hawaii is on top of a "hotspot" or a very weak spot in the crust where the mantle breaks out, hardens and forms a volcano.
When a volcano erupts, it releases hot melted rock called magma, which then solidifies into solid rock. When enough of this rock has been released underwater, the result is an island.
Holes in a rock that result from rapid cooling are called vesicles. These form when gas bubbles trapped in molten rock solidify before they can escape, leaving behind cavities in the rock as it cools and hardens.
The lava with a wrinkled surface that forms when mafic lava hardens is called pahoehoe. It is characterized by smooth, undulating, or rope-like textures that result from the flow of lava as it cools and solidifies. Pahoehoe lava flows typically have a low viscosity, allowing the lava to move easily and form these distinctive features.
Volcanoes don't help plate tectonics; volcanoes are the result of plate tectonics.
No. Volcanoes are the result of processes inside the earth. Weather has nothing to do with it.
Andesitic magma will result in the formation of a stratovolcano, also called a composite volcano.
