What else can I help you with?
Where can you find stalactites and stalagmites other than caves?
Stalactites and stalagmites can also form in underground tunnels, lava tubes, mines, and man-made structures like abandoned buildings and tunnels. They require a source of water to form as minerals are deposited over time.
Is this statement correct Stalagmites form on the ceiling of a cavern?
No, it is stalactites that form on the ceilings. Stalagmites form on the cavern floors.
What stalactites is the hardest mineral?
Stalactites made of calcite are relatively soft, while those made of aragonite are harder. However, the hardest mineral commonly found in stalactites is quartz, which can form as chalcedony stalactites in caves.
What do stalactites and stalagmites join to form?
Stalactites and stalagmites join to form columns. These columns are created when a stalactite hanging from the ceiling of a cave and a stalagmite growing from the floor eventually meet and fuse together.
Rilles are associated with what lunar features?
Rilles are associated with lava tubes on the Moon, which are long and narrow channels formed by flowing lava. They can also be found in areas with collapsed lava tubes or where the surface has been disrupted by volcanic activity.
What is the difference between how two common cave features -- stalactites and stalagmites -- form in limestone caves and how they form in lava tubes?
Stalactites and stalagmites in limestone caves form through the precipitation of calcium carbonate from dripping water that has dissolved limestone, with stalactites hanging from the ceiling and stalagmites rising from the floor. In contrast, lava tubes, formed by flowing lava that cools and hardens, can develop formations like stalactites and stalagmites made of mineral deposits from volcanic gases or cooled lava drips, but these are typically less common and have different compositions, such as basalt. The formation processes and the materials involved differ significantly due to the distinct geological environments of limestone caves and lava tubes.

Tubes with hollow centers?
Stalagmites
Does Yellowstone volcano have lava tubes?
Yes, Yellowstone volcano has lava tubes formed by past volcanic activity. These tubes are created when lava flows beneath the surface and eventually solidifies, leaving behind hollow tunnels. However, these lava tubes are not as prevalent or well-known as those found in some other volcanic regions.
Would a'a form lava tubes or pahoehoe?
Both a'a and pahoehoe lava types can create lava tubes, but pahoehoe lava usually forms smoother, more continuous tubes due to its lower viscosity and higher flow rates. A'a lava tubes are typically more irregular and blocky, formed by the slow-moving, cooler outer crust of the flow.
Is a'a or pahoehoe lava better for making lava tubes?
Lava tubes are usually produces by pahoehoe.
How do lava tubes form and what role do they play in the formation of volcanic landscapes?
Lava tubes form when flowing lava cools and solidifies on the surface while the molten lava continues to flow beneath, creating a tunnel-like structure. These tubes play a significant role in the formation of volcanic landscapes by allowing lava to travel long distances underground, preserving heat and fluidity, and eventually emerging as surface flows, shaping the terrain with their unique structures and patterns.
What is melted rock that has been exposed to earths surface?
'Magma' while it is still in or below the Earth's surface and when it reaches or flows out on the Earth's surface it is called 'lava'. Magma from the 'magma' chamber can form a 'lava lake' at the surface and the lake can drain down the volcano in 'lava tubes' to form 'lava flows' or 'pillow lavas' if the lava tubes drain into the sea.
Where do stalactites form?
in caves

How are lava tube caves and mount Pinatubo the same?
They both depend on eruptions for their formation but lava tubes form only in large flows of low-viscosity, basaltic,lava. I don't know if this applies to Mt. Pinatubo.
How long does it take for a lava cave to form?
That's extremely variable and specific to each cave, but you have to think in tens or hundreds of thousands of years.
