Cone shaped deposits that rise from the floor of a cave are called Stalagmites. This is easy to remember as it contains a letter 'G' as does ground. While a Stalactite, which hangs down from a cave ceiling, contains a letter 'C.'
If you are talking about the large crater created after a volcano errupts, then it would be a caldera. They are formed after the magma chamber is emptied, when the cone of the volcano collapses to fill the empty space.
Some do. But that is caused by immaturity or herniation. But it isn't the nipples that are cone-shaped, but everything, areolae too.
A cone shaped mountain formed from layers of lava and ash (tephra, cinders) is called a 'composite volcano' or a 'stratovolcano'. Both names refer to the alternating layers.
cinder cone volcanoes: consist of primarily erupted volcanic ash and rock fragments, or cinders. When the volcano erupts the ash and rock are ejected onto the mountain. As this process continues the volcano "grows" higher because of the debris build up.
Jean Paul Gautier
A cone shaped mountain that is built from layers of lava is called a volcano.However, that description does not quite fit any of the three accepted descriptions of the world's volcanoes.A dome shaped mountain built from layers of lavais called a 'shield volcano'.A cone shaped mountain built from layers of cinders (tephra) is called a 'cinder cone' or a 'cinder cone volcano'.A cone shaped mountain built from alternating layers of lava and cinders is called a 'composite volcano'.
