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.....
by lava
Still-molten lava running out from below the solidified crust of a large lava flow.
Erosion, with the exception of lava tubes that result from molten rock running out from beneath the solidifiedcrust of a lava flow.
Erosional caves are formed by the action of water or wind.
Because it blows around so much that the wind stops erosion. This answer may not be right but it should be close. So look it up somewhere else. +++ Assuming it was a genuine question, I offer a genuine answer rather than nonsense that is neither right nor close. Caves except lava-tubes are themselves erosion features, the majority by dissolution of limestone by water flowing through the joints etc in the rock mass. External erosion will in time remove a cave as it removes the land that held it. Sea-caves are formed by wave action on the cliff.
lava formed the volcanic mountains
Yes, inactive volcanos will have lava tubes that are just like caves, they are the paths molten lava took to get to the surface.
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).
Constructive: natural features in karst landscapes (the vast majority of them)or in basalt-lava flows (lava-tubes)
Still-molten lava running out from below the solidified crust of a large lava flow.
Basaltic, low viscosity lava would form lava tube caves.
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.
None.In USA? Caves can only form in limestone, with a few exceptions such as lava tubes, so does every Americanstate contain karst landscapes then?
More accurately I think you mean "What type of rocks hold caves?" The majority of caves are in Limestone; some in its metamorphic edition, Marble. These, "karst" caves, often also hold calcite deposits (stalactites etc) formed by precipitation of the calcium carbonate dissolved from the rock above the cave by the water oozing through its joints. There are also lava tubes in basalt lava, formed by molten rock flowing from below a solidified crust. Sea-caves and mass-movement fissures can occur in most competant rocks.
The most famous spot for lava tubes on Earth is Hawai'i. Because of the geography, the Lava Tubes on Big Island are the biggest in the World. Kazumura Cave is 61.407 m long and has a height difference of 1102 m from end to end.

Caves are formed through various geological processes. The most common type of cave is a solution cave, which forms when water containing carbon dioxide dissolves limestone or other soluble rocks over a long period of time. Other types of caves include lava tubes, which form when molten lava creates tunnels, and sea caves, which are formed by the erosive action of waves on coastal cliffs.
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.
