It is a sink hole if it reaches the surface.
The correct term is false ceiling. Fall ceiling isn't correct.
A ceiling partition is a track on the ceiling that may have a metal or wooden wall fitting into it. This divides a room by the ceiling support.
Penn's Cave is located in the topographic region of Pennsylvania known as the Ridge and Valley. According to the studies done in the 1970's Penn's Cave contains 600,000 feet of volume. Penn's Cave is 30 million years old. The Caves in Pennsylvania are of four principle patters, which are Linear, Angulate, Branch Work and Network Mazes. Penn's Cave was formed in the Nealmont and Linden Limestone formations of the Ordovician Age.
' types of ceilings can a) contact ceiling b) suspended ceiling c) furred ceiling
a suspended ceiling
A sinkhole is formed when the roof of a cave collapses.
When rock above a cave collapses, a sinkhole is formed.
A sinkhole forms.
A large hole formed when a roof of a cave collapses.
A large hole formed when a roof of a cave collapses.
Shakehole or Sinkhole - when the collapse extends to the surface. (Not all cave roof collapses disturb the surface above.)
Collapsed caves are often referred to as sinkholes. This occurs when the roof of a cave collapses, creating a depression or hole on the surface. Sinkholes can pose dangers to infrastructure and properties located above them.
When rock above a cave collapses, a sinkhole is formed.
Stalactites. You may also notice distinct erosion patterns in many cave ceilings, formed when the passage was filled with water at an earleir stage in the cave's development.
Stalagmites are formed when mineral-rich water drips from the ceiling of a cave and deposits calcium carbonate, which crystallizes and accumulates over time to create a conical or mound-shaped structure on the cave floor.
Cave icicles, or stalactites, are formed when mineral-rich water drips from the ceiling of a cave. As the water evaporates, it leaves behind small deposits of minerals that accumulate over time, eventually forming long, pointed icicle-like structures hanging from the cave ceiling. This process can take thousands of years to create noticeable stalactites.
Stalagmites grow from the ground in caves. They are formed by the accumulation of minerals deposited by water dripping from the ceiling of the cave.
