yes, because when you heat up the magma the molecules start moving faster which means it will be more fluid"ish." Kind of like an internal friction.

Does an increase in silica increase the viscosity of magma?
Yes. Viscosity is the resistance of a fluid to flowing. A high viscosity means low flowing (I specifically mention this because this is a huge pitfall) When silica content increases, and when temperature decreases, the viscosity of a magma increases along with it.
The hotter the magma or lava the greater lower visiosity?
The viscosity is lowered as molten rock heats up. A good analogy is warm honey versus cold honey. As the honey cools down it's molecules slow down and an increase in viscosity occurs.
Is basaltic magma or granitic magma hotter?
Baslatic magma is hotter.
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
What Tend to increase the explosive potential of magma body beneath a volcano?
high viscosity and dissolved gas
What mainly determines the viscosity of a magma?
Viscosity is the measure of a liquids resistance to flow. In the case of magma, the hotter it is, the lower the viscosity.
What is the difference in silica content and viscosity between light color and dark colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.

What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.
Which conditions make for a violent volcanic eruption?
Magma with low viscosity
What conditions make for a violent volcanic eruption?
Magma with high silica content
Is basaltic or andesitic magma hotter?
Basaltic magma is hotter than andesitic magma.
