pillow lava named that because when it cools it looks like pillows.
Basaltic magma is produced at the coolest temperatures because it has a lower silica content and therefore has a lower melting point compared to other types of magma. This type of magma typically erupts quietly and forms basaltic rock, such as the kind found at mid-ocean ridges.
Mount Shasta typically has andesitic magma, which is a type of intermediate magma that is common in subduction zone environments. This type of magma is rich in silica and forms from the partial melting of both oceanic and continental crust.
A divergent boundary forms when two plates pull apart. As the plates move away from each other, magma rises to fill the gap, creating new crust. This process can result in the formation of mid-ocean ridges.
When magma cools and solidifies, it forms igneous rocks such as granite, basalt, or obsidian. The specific type of rock that forms depends on variables such as the composition of the magma, cooling rate, and environment in which it solidifies.
The color of the rock that forms oceanic crust at mid-ocean ridges is dark gray to black. The rock is primarily basalt, which is a type of igneous rock formed from the solidification of molten lava.
Basaltic magma is produced at the coolest temperatures because it has a lower silica content and therefore has a lower melting point compared to other types of magma. This type of magma typically erupts quietly and forms basaltic rock, such as the kind found at mid-ocean ridges.
(1)midocean spreading ridges, (2) subduction zones, and (3) transform faults.Normal fault, Reverse fault, and strike-slip fault

Ash and poised magma that will turn into Metal!
magma is a mixture of several different types of rock.
Gaseous thick magma equals massive explosion.
