pressure and temperature
Things
Lava and Magma
Volcanoes.
magma can be generated from solid rock by three things:1. decress in PRESSURE2. increase in TEMPATURE3. addition of VOLATILES
Increasing pressure pushes the magma upwards. This rising pressure can be caused by many different things.
Silica and pressure
The two main types of magma are mafic and felsic.
it gets melted into magma, then it is cooled into igneous rock.
Things
Magma can be classified in the two ways. When it is inside the volcano it is called magma, but when it is out of the volcano, it's then called lava.
Rhyolitic magma. Boom! Basaltic magma is its exact opposite, while andesitic magma is in between the two.
barbed wire and locomotive
"Which" is when you have a choice between two or more things, such as "Which car do you drive?" "Witch" is a person who does witchcraft.
Lava and Magma
The three things that determine how thick or thin magma is temperature, silica content, and gas content.
Steam is produced. The steam pressure can be used to drive turbine or piston driven electrical generators.
