Stalagmites and Stalactites

Stalagmites and stalactites are mineralized deposits formed by dripping water. The deposits are long and cone shaped. Stalactites hang from the tops of caves, and stalagmites are formed on the floors.

350 Questions

Stalactites grow up from the bottom of a cavern floor due to deposit of minerals over time?

Stalactites form on the ceiling of a cave when mineral-rich water drips down and leaves behind deposits of minerals like calcium carbonate. Over time, these minerals accumulate and harden into the characteristic icicle-shaped formations.

What is an example of stalactite?

An example of a stalactite is the formation found in caves, made of mineral deposits dripping down from the ceiling over time. These formations often have a long, cylindrical shape and can vary in size and color depending on the minerals present in the water.

What causes the formation of most caves as well as stalactites and stalagmites?

Running water, and the acids from dissolved gases, slowly carve out the stone to form an erosive cave. Where limestone is present above the cave, it will drip out as calcium bicarbonate in water, which reverts to particles of calcium carbonate in air. If the water carries to the floor of the cave, stalagmites (limestone pinnacles) are formed. If the calcium precipitates before it can drip, an "icicle" of limestone, a stalactite, hangs from the ceiling. Usually these forms are created simultaneously, and may merge to form columns or sheets of columns.

Unlike their icy counterparts, stalactites and stalagmites take hundreds to thousands of years to form, at an average of 5/1000ths of an inch (.13 mm) a year. A stalagmite in an Oregon cave has grown less than 1/4 of an inch since it was broken off 100 years ago!

Where do stalagmite and stalatites form?

They typically form in caves where they can grow undisturbed for hundreds of years. Stalagmites grow from the floor up and stalactites stick to the ceiling. Dripping water deposits minute amounts of limestone that build up over the years.

You do sometimes find small, rather coarse versions growing under bridges etc.built from bricks or ashlar masonry and mortar. Here, the calcite that is their constituent mineral has been leached from the structure's mortar. However caves in limestone (the rock hosting by far the majority of caves) are the natural home for stalagmites and stalactites, and their related formations.

How does stalagmites look like?

Stalagmites are rock formations that grow upward from the floor of a cave. They are typically cone-shaped with a pointed tip and can vary in size and shape depending on the minerals in the groundwater that drips from the ceiling of the cave. Stalagmites are created as mineral deposits accumulate over time, forming unique and often intricate patterns.

What do you call when a stalagmite and stalactite form together?

When a stalagmite and stalactite meet and grow together, they form a column or pillar. This occurs when mineral-rich water drips from the ceiling and deposits mineral material that builds up from the ground.

Are stalagmites made of limestone?

Yes, stalagmites are typically made of limestone. They form from mineral deposits left behind by dripping water in caves, which contain calcium carbonate. Over time, these deposits accumulate to form the stalagmites.

What are Stalactites and stalagmites in caves?

Stalactites are formations that hang from the ceiling of a cave and are formed by water dripping and leaving mineral deposits behind. Stalagmites are formations that grow up from the cave floor as a result of mineral deposits accumulating from water dripping onto the cave floor. Over time, stalactites and stalagmites can grow towards each other and eventually merge to form a column.

What causes stalagmites?

Stalagmites are formed in caves when mineral-rich water drips from the ceiling and deposits minerals on the cave floor. Over time, these mineral deposits accumulate and harden into cone-like structures known as stalagmites.

Where is the worlds biggest stalactite?

The world's largest stalactite is located in the Jeita Grotto in Lebanon. It measures at 27 feet long.

Formation of stalagmites in a cave?

Stalagmites are formed when the stalagtite above it drips small amounts of liquid onto it and it slowly hardens and keeps forming upward. It takes about 100 years for a stalagmite to grow 1 inch.

What is a drip curtain?

A drip curtain is a narrow strip of fabric, often made of plastic or vinyl, that hangs vertically to direct water away from a window or door. It helps to prevent water from seeping in through gaps or cracks during rain or storms.

Do Stalactites grow up from the bottom of a cavern floor due to the deposit of minerals over time?

No, stalactites grow from the ceiling of a cavern due to mineral-rich water dripping down and leaving behind deposits that accumulate over time. Stalagmites, on the other hand, grow up from the cave floor as mineral deposits build up from dripping water.

How do stalagmites grow 'upwards'?

Stalagmites grow upwards from the floor of a cave due to the accumulation of mineral-rich water dripping from the ceiling. As the water drips and evaporates, it leaves behind mineral deposits like calcite which gradually build up over time, forming the stalagmite structure. This process can take thousands of years for a stalagmite to reach significant height.

From which part of the cave do stalactites grow?

Stalactites grow from the ceiling of a cave. They are formed by mineral-rich water dripping from the cave ceiling and leaving behind deposits of minerals that accumulate over time, creating a cone-like structure.

How are ice stalactites formed?

Ice stalactites are formed when water drips downwards and freezes on the lower end of a surface, such as a roof or icicle. As more water continues to drip and freeze, the stalactite grows in size. Factors such as temperature and humidity levels can affect the formation of ice stalactites.

What is the tallest stalagmite in Europe called?

The tallest stalagmite in Europe is called "Hallelujah" and it is located in the Grotte de Clamouse cave in France, measuring about 70 meters (230 feet) in height.

What do you call Stalagmite and Stalactite when they touch each other?

When a stalagmite and stalactite meet and grow together, they form a column.

How many years does it take for a stalactite to grow?

Stalactites typically grow at a rate of 0.01 to 0.02 inches per year. It can take hundreds to thousands of years for a stalactite to grow to a noticeable size, with some of the largest ones taking tens of thousands of years to form.

True or false Stalactites attach to the top of a cavern ceiling and hang down?

True. Stalactites are mineral formations that hang from the ceiling of a cavern or cave, formed by dripping water containing minerals that slowly build up over time.

Where is the largest stalagmite in the world?

Many caves around the world report having the "world's largest stalagmite," but these are often unsupported claims.

As featured on the BBC series "Planet Earth," the largest recorded stalagmite is in the cave of Cueva San Martin Infierno, Cuba. It measures 62.2 metres (220 feet) high.

There is still the possibility of a larger stalagmite being found, as many cave systems across the world are as of yet unexplored, or have not been documented.

Which one of the following statements is correct A Stalagmites are narrower than stalactites B Stalagmites form on the ceiling of a cavern C Stalagmites are formed from water containing salt?

The only statement actually listed is not correct, at least not always. (We're really not ideally set up here for multiple choice questions.)

the answer is: Stalagmites are coned-shaped deposits.

D is correct. Stalagmites are cone-shaped deposits.

As a general rule C is wrong, certainly in limestone; but Iranian cavers recently discovered a beautiful cave formed entirely by dissolution of the salt in a massive rock-salt bed; and this contains really lovely salt-crystal formations!

A more common exception is gypsum - calcium sulphate - which often appears as lovely, fine porcupine quill-like elongated crystals, on the clay which it is its mineral source.

Are there different kinds of stalactites and stalagmites?

Yes, there are various types of stalactites and stalagmites based on their composition, shape, and formation process. Some common types include soda straws, helictites, and draperies for stalactites, and pillars, shields, and coral garden for stalagmites. Each type has unique characteristics formed under specific conditions in caves.

What is a first stage stalactite called?

A soda staw represents the earliest stage of stalactites. A soda straw is like a thin tube attached to the ceiling.
