How are lava tubes caves formed?

butter........juicy buttery butter........yummy bacon and eggs and opps forgot the best part baby sausage weinie things! HAHA no its formed at your mamas house lol! stupid i no but just laugh.....


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.


Differences between lava and ash landforms and magma landforms?

Lava landforms are created by the eruption and cooling of molten lava on the Earth's surface, forming features like lava flows, lava domes, and lava tubes. Ash landforms are the result of volcanic eruptions that produce ash and volcanic debris, creating features like cinder cones, ash clouds, and pyroclastic flows. Magma landforms are underground structures formed by the cooling and solidification of magma, such as plutons, batholiths, and dikes.


What 2 igneous are formed by fast cooling lava?

Two igneous rocks formed by fast cooling lava are basalt, which is a fine-grained volcanic rock, and obsidian, which is a natural glass formed from rapidly cooling lava without crystal growth.


Pumice obsidian and scoria are kinds of?

volcanic rocks formed from different processes. Pumice is a light and porous rock formed from foamy lava, obsidian is a dark volcanic glass formed from quickly cooled lava, and scoria is a dark, vesicular rock formed from gas-rich lava.

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.


Did onyx originate from lava?

Onyx is a type of mineral formed from the deposition of calcium carbonate in caves. It is not directly formed from lava but can sometimes be found in lava tubes or caverns where it is deposited by water flowing through the rock.


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.


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.


Is a'a or pahoehoe lava better for making lava tubes?

Lava tubes are usually produces by pahoehoe.


How do lava tubes caves formed?

Lava tubs form as a result of pahoehoe lava flows. As one of these flows progresses, it builds of a layer of rock on top of it. eventually, thus becomes thick enough to support is own weight, and forms an insulating tube through which lava can flow.


How many caves are formed by erosin?

All except lava-tubes, which result from lava draining from under the solidified crust of a lava flow. Most are in limestone, soluble in water acidified by carbon-dioxide from the atmosphere (chemical weathering).

Which features may occur when volcano lava cools at the surface?

Lava that cools at the surface can form features such as lava flows, which are large sheets of solidified lava. It can also create lava tubes, which are tunnels formed when the outer layer of the lava flow cools and hardens while the inner lava remains molten and continues to flow. Additionally, lava may form spatter cones or lava fountains when ejected into the air and solidifies before hitting the ground.


What rocks are formed after lava dries out?
