Does gas in lava makes it more or less explosive?
Gas in lava can make it more explosive. When gas bubbles within the lava are trapped and then released during an eruption, it can lead to more violent explosions. The pressure from the gas causes the lava to fragment into smaller pieces, creating explosive eruptions.
Does lava turn into a rock when it cools?
Yes, when lava cools and solidifies, it forms igneous rock. The type of rock that forms depends on the chemical composition of the lava and the rate at which it cools.
What is the origin of vesicles in basalt?
Vesicles in basalt are formed when gas bubbles trapped in magma during volcanic eruptions cannot escape and become preserved as the lava cools and solidifies. These gas bubbles create the small cavities observed in basaltic rocks.
How is the rock pumice made?
Pumice is formed by the rapid cooling of gas entrained (frothy) felsic lava which is erupted from volcanoes. If the amount of trapped gases in the lava is high, and cooled quickly enough to trap the bubbles of gas before they can escape, vesicular pumice will be formed, resulting in the only igneous rock that is able to float in water.
Lava rock with air pockets?
Lava rock with air pockets are known as vesicular lava rock. These air pockets are formed during the solidification process of lava, which traps gas bubbles within the rock. This gives the rock a porous and lightweight texture.
What does obsidian turn into after lava cooks it?
nothing, its a volcanic gas that hardens
Is lava flow found on any of the gas giants?
No. Gas giants do not have a solid surface on which lava might flow.
Does lava cool down in the air?
No. Lava heats up the air. In turn, the air cools the lava.
How does a rock turn into lava?
The rock becomes too hot that it must turn into liquid form (lava). This would usually mean that the rock had to have come into contact with lava first.
Does balsaltic lava have a high gas content?
Basaltic lava typically has a low gas content compared to other types of lava such as andesitic or rhyolitic. This is because basaltic lava is less viscous, allowing gases to escape more easily, resulting in less gas being trapped within the lava as it erupts.
Is it Obsidian a natural gas?
Obsidian is a type of glassy lava not a gas.
What can obesidian turn into?
Obesidian can turn into Lava when it is hot outside and may turn into Soft and smooth
What is the importance of a silica and oxygen in lava flow speed?
Silica and oxygen content in lava affects its viscosity, which in turn impacts flow speed. Lava with higher silica content tends to be more viscous and flows slower, while lava with lower silica content flows faster. The presence of oxygen also influences lava's ability to flow by affecting its gas content and pressure.
What shoots out of a volcano during an eruption?
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
Does gas in lava makes it more or less explosive?
Gas in lava can make it more explosive. When gas bubbles within the lava are trapped and then released during an eruption, it can lead to more violent explosions. The pressure from the gas causes the lava to fragment into smaller pieces, creating explosive eruptions.
What type of rock does rock turn into when it erupts?
lava
What materials come out the volcanoes?
Ash, Gas, and Lava
