One formed below the solidified surface of a low-viscosity (basltic) lava flow by still-molten rock flowing out from under it.
What else can I help you with?
What is the tunnel where the lava travels to the top called?
lava tube
Why would lava flow faster through a lava tube than it would above ground?
The solidified lava forming the walls of the lava tube will act to insulate the molten lava. It will therefore cool more slowly than lava at the surface and so will have a lower viscosity (it will be more runny) and so will flow faster than lava at the surface.
Where do lava tube caves form?
Lava tube caves form when low viscosity lava flows beneath the hardened surface of lava flow while the volcano is active. Then when the volcano is dormant or extinct, it leaves cave like channels.
Which type of lava would most likely form lava tube caves?
Pahoehoe lava, which has a smooth, rope-like texture and forms by flowing rapidly and cooling quickly, is more likely to form lava tube caves due to its ability to retain heat and flow for long distances before solidifying. Aa lava, with its jagged and blocky texture, tends to move more sluggishly and is less likely to create extensive tube structures.
What is a lava tube cave?
A lava tube cave is a natural tunnel formed by the flow of lava, creating a channel for molten lava to move through during a volcanic eruption. When the lava flow stops, the tube can cool, leaving behind a cave-like structure with unique geological features.
What is the hole in a lava field where you can seethe lava?
The hole in a lava field where you can see lava is often referred to as a "lava tube" or "lava vent." These openings form when the surface of a lava flow cools and solidifies while molten lava continues to flow beneath, creating a tunnel-like structure. In some cases, the roof of the lava tube can collapse, exposing the lava inside. Such features can provide spectacular views of flowing lava, especially in active volcanic regions.
What is passage followed by magma?
The tunnel is called a lava tube or magma tube.It's called a conduit.conduita tube or vent tube
What is the tube that lava travels through?
It travels through a "Pipe" and explodes out the "Vent", or possibly the "Side Vent", and another world for the hole at the top is the Crater.
How are lava tubes formed?
Lava tubes are formed when lava flows through a hardened outer crust, creating a tunnel-like structure. As the lava continues to flow, it leaves behind an empty space that eventually forms a tube. These structures can be maintained over time if the lava continues to flow and the tube remains intact.
What is the difference between lava flow lava fountains and lava tubes?
A lava flow is basically a stream of lava on the surface. A lava tube is an underground cave through which lava flows downhill. A lava fountain is lava shooting into the air out of a volcano in much the same manner as a water fountain.
What is the phenomenon that occurs when molten lava flows through a natural tunnel-like structure underground, known as a lava tube, and what travels through it?
The phenomenon is called lava tube formation, where molten lava flows through a natural tunnel-like structure underground. Lava travels through these tubes, allowing it to move further away from the volcanic vent.
Can intense heat form a cave?
no +_++ With one exception, the Lava Tube! This results from still-molten lava flowing out from beneath the solidified crust on a mahjor lava flow.
