A stalactite is very much slower.
it takes 1 million years for a stalagtite to grow 1 cm
a column
Human hair can not grow visibly longer overnight, sorry.
The result is called a "column".
Yes, a stalactite can grow without a corresponding stalagmite below it. If there is a river flowing under the water seeping through the rock, the stalactite will grow while the river will sweep away the mineral rich water.
nine months
On average they grow at 1 mm a year.
It takes a longer time to grow
It grows to be about 4 to 5 feet
Stalactites and stalagmites are slightly different in their growth and do not depend on each other to grow. A stalactite grows when calcium carbonate and other ions precipitate out from the groundwater. A stalagmite forms when calcium carbonate and other ions precipitate out from the groundwater. This water does not need to come from stalactites. When a stalactite and a stalagmite do grow with one above the other, they are called a column when they meet.
Takes 4-6 weeks to grow a good length of hair.
as we grow, it takes longer to heal.
