Valcano :)) ......
~Your Welcome~ ♥
its called a vent , what comes out of it is called lava instead of magma.
You put this under the category of 'volcanoes'. I think you already know.
This is known as a volcanic vent.
Earthquakes are caused by a shift in two different plates beneath the earths surface. The shift is usually caused by convectional magma flows underneath the earths crust. This is because the plates are purely floating slabs of rock on the magma beneath it. The layer beneath the crust is called the mantle.
No, earthquakes can occur anywhere in the crust, oceanic crust or continental crust. An earthquake occurs when the hard brittle solid material of the crust fractures under stress. Earthquakes cannot occur deeper than the crust (the mantle is plastic and flows slowly under stress instead of fracturing, the outer core is liquid and flows even easier than the mantle).
Crater or vent. Sometimes lava also comes from fissures as well. However crater is the most commonly used term.
The opening through which menstrual flow flows is the vaginal opening. Menstrual flow leaves the uterus via the cervix and then passes through the vaginal canal.
