Does lava and water make obsidian? Obsidian is formed from quickly cooled lava, which is the parent material. Extrusive formation of obsidian may occur when felsic lava cools rapidly at the edges of a felsic lava flow or volcanic dome, or when lava cools during sudden contact with water or air.
Does water and lava make obsidian in real life? obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes.

Does water and lava make obsidian in Minecraft? There is no crafting recipe for obsidian. Instead, any time flowing water hits a stationary lava “source” block, the lava turns into obsidian.
What controls lava flow? Many variables influence lava flow, from the temperature, the slope of the hill, the material it flows over, to the viscosity. … The viscosity, for example, can determine everything from how fast the lava moves, to when it will stop flowing, to its final shape, Karson explains.

Which layer of the earth has lava?

Can cooled lava be melted?
Yes, at least partially. It is important to remember that a “rock” usually does not have a single melting point. It melts over an interval. Igneous (magmatic) rocks are made of combination of minerals (for example, quartz, olivine, pyroxene, feldspar) that each will melt at a different point.
Which boundary or type of volcano produces very fluid lava?
Shield volcanoes have the following characteristics: Basaltic magma, which is high in temperature, very low on silica and with low gas content. This type of magma produces fluid lava with very little explosive activity.
Is lava less dense than crust?
This molten material is called magma. It is less dense than the surrounding rock so it tends to move upwards through the crust.
What type of gas is in lava?
