Which of the following can be caused by excessive pressure from overlying structures over a cavern?
Excessive pressure from overlying structures over a cavern can cause the collapse of the cavern roof, leading to sinkholes, subsidence of the ground surface, or even a catastrophic cave-in event.
Do stalactites form quicker than stalagmites?
No, stalactites generally form more slowly than stalagmites. Stalactites are formations that hang from the ceiling of caves and are created by mineral-rich water dripping from above, while stalagmites grow from the ground up as mineral deposits accumulate from water dripping onto the cave floor. The rate of growth for both formations can vary depending on factors like the mineral content of the water and the size of the cave.
How does the formation of stalagmites and stalactites in caves are relate to equilibrium?
Stalagmites and stalactites in caves form through the process of calcium carbonate-rich water seeping through rocks, depositing minerals as it drips. The formation reaches equilibrium when there is a balance between the rate of mineral deposition and the rate of water dripping. This equilibrium helps maintain the growth of stalagmites and stalactites over time in caves.
What stacticals and stalagmites are formed from?
Stalactites are formed from mineral deposits left behind as water drips and evaporates from the ceiling of a cave. Stalagmites are formed from the same mineral deposits, but build up on the cave floor as water droplets fall and leave behind minerals as they evaporate.
Stalactites can come in a variety of colors, depending on the minerals present in the rock or cave from which they are formed. Common colors include white, brown, red, and orange due to the presence of calcium carbonate, iron oxides, or other minerals.
Is there a rhyme to remember stalactites and stalagmites?
Yes! "Stalactites hold tight to the ceiling, while stalagmites might reach the ceiling." This rhyme can help you remember which formations grow up from the ground and which ones hang down from the ceiling of a cave.
What is a stalactite made from?
A stalactite is made of mineral deposits, typically calcium carbonate, that accumulate as water drips from the ceiling of a cave. Over time, these deposits form a cone-shaped structure that hangs down from the cave ceiling.
What are three types of stalagmites?
Are stalactites a type of crystal?
No, stalactites are not a type of crystal. They are formations that hang from the ceiling of caves, formed by mineral deposits dripping down over time. Crystals, on the other hand, have a more defined geometric structure and can form in a variety of environments.
Do stalagmites grow on the top or bottom of a cave?
Stalagmites grow on the bottom of a cave floor. They form when mineral-rich water drips from the ceiling and deposits minerals that build up over time, creating the distinctive cone-shaped formations.
How big is the biggest stalactite?
The biggest stalactite in the world is located in Jeita Grotto in Lebanon, and it measures over 27 feet long. Stalactites can vary in size depending on the location and conditions where they form.
Why are stalagmites stronger than stalactites?
Probably since stalgtites cling to the ceiling and earth's gravity is constantly pulling them downward. Stalagmites have a more stable base
Acidic ground water (rain-water that has absorbed atmospheric carbon dioxide to form carbonic acid) dissolving the limestone as it flows through the joints & other discontinuities in the rock mass.
As well as forming the cave passages, the calcite held in solution may precipate on exposure to the cave air as the solution emerges from a joint in the cave roof, to develop stalactites & stalagmites.
How old is the oldest stalactite?
The oldest stalactite is estimated to be around 190,000 years old. Stalactites form when mineral-rich water drips slowly from cave ceilings, depositing minerals over time. These formations can provide valuable insights into past climate conditions and geological processes.
How many inches does a stalactite grow in a year?
A stalactite typically grows at a rate of around 0.001 to 0.02 inches per year, depending on factors like the mineral content of the water and the size of the stalactite.
Why stalactite and stalagmite is important?
Stalactites and stalagmites are important because they are structures formed in caves through the deposition of minerals from dripping water, helping to create unique and diverse cave environments. They can provide valuable information about past climates and geological processes through the study of their growth patterns and composition. Additionally, stalactites and stalagmites are important for cave ecosystems, providing habitats for various organisms to thrive.
Why are our ice cubes growing handles upward like stalagmite in my ice cube tray?
Basically they form kinda like mini-volcanos. The ice cube freezes at the top first, from the outside edges in, and under the right conditions you can be left with a tiny hole somewhere in the middle that isn't frozen yet.
Ice takes up more volume than water since it forms crystals as it freezes. The expanding ice forces the remaining water up through the hole, where the outside of the bulge of water freezes. The inside remains liquid and continues to push upward. This continues, forming a longer and longer spike until either the end of the spike freezes over or the ice cube runs out of water to push up through the spike due to it all freezing.
Distilled water works best, since any impurities in the water can act as nucleation sites and make the hole freeze up before the ice spike forms.
Did Stalactites grow up from the bottom of a cavern floor due to the deposit of minerals over time?
No, stalactites grow downward from the ceiling of a cavern due to the dripping of mineral-rich water, usually calcium carbonate, which solidifies and forms the stalactite over time. Stalagmites, on the other hand, grow up from the floor of the cavern due to the mineral-rich water dripping onto the ground.
Stalactites are natural formations found in caves that are formed by the slow dripping of mineral-rich water. While they are unique and beautiful to observe, they do not hold significant monetary value like precious gemstones or metals. Their value lies more in their aesthetic appeal and scientific significance.
How do you determine the age of a stalactite 10.5 inches long?
The age of a stalactite is determined by calculating the rate at which it grows, typically between 0.13 to 0.25 inches every 1,000 years. Using this growth rate, a 10.5-inch long stalactite would be estimated to be between 42,000 to 80,770 years old.
Stalactites can come in a variety of colors, including white, brown, amber, and even shades of pink or green. These colors are often influenced by the minerals present in the water that drips from the ceiling of a cave, which solidify over time to form the stalactites.
Why do stalactites grow on cellings?
Stalactites grow on ceilings because mineral-rich water drips from the roof of a cave, leaving behind deposits of calcium carbonate as the water evaporates. Over time, these deposits build up and harden into the cone-shaped structures known as stalactites.
Do stalagmites grow from the ceiling or the ground?
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.
What grows faster from stalactites and stalagmites?
I'd guess stalagmites. Stalagmites are formed when water and acids are dripping from a stalactite...for a stalactite to form there must be years of oxidization, but I guess a stalagmite could be made at 4-5 years...
+++
They probably grow at similar rates, at least by volume if not necessarily by length, and the rate is probably fairly specific to the individual site.

Add 00 to those figures. None have been found to grow in 4-5 years, though scientists studying deposits in one Italian caves were startled to find a glass bottle only a few decades old inside one stalagmite! That is exceptionally fast. Normally, these formations, which grow by precipitation of calcium carbonate, not by oxidation or dripping acids, take hundreds or thousands of years to grow.
