Watch out for that magma!
Lava
Granite
Exploding magma
Igneoous rock is made from cooling of magma. Obsidian is a classic example of igneous rock.
Granite is one example.
A non-example of magma would be any solid rock found on the Earth's surface or within the Earth's crust. Magma is molten rock located beneath the Earth's surface, whereas solid rocks like granite, basalt, or sandstone are not examples of magma. Additionally, substances such as water, air, or metals are also not examples of magma, as they do not have the same chemical composition or physical properties as molten rock.
A type of rock group that forms from the solidification of magma is indigenous rocks. One example of this is sulphur.
The ratio of the concentration (by weight) of an element (e.g. Ti) in a crystallizing mineralto its concentration in the magma. For example, KTi = [Ti]min./[Ti]magma, where kTi is the partition coefficient for Ti, and [Ti]min. and [Ti]magma are the concentrations of Ti in the mineral and magma respectively. The value of k is dependent on temperature, pressure and the composition of crystallizing mineral and magma.
Magma when it hardens is an example of spreading. In Global Studies form
A laccolith is an example of an igneous intrusion, which is a body of intrusive igneous rock that forms by magma uplifting and pushing overlying rock layers.
this answer has to do with density if magma becomes less dense than rock it will rise to the top ,for example vegetable oil in water.
