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 basaltic or andesitic magma hotter?
Basaltic magma is hotter than andesitic magma.
Does cooler magma flows more or less quickly than hotter magma?
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
What causes it to erupt?
Sometimes the plates on the earths crust crash into each other, forcing one to go lower. The friction causes the rock to get hotter and hotter until it melts. This is called magma. The magma keeps getting hotter, but it needs somewhere to go, so it surges up through the earths crust, making a hole. That is how a volcano is made. Once the hole is made, magma from the earths core comes to the surface, causing the volcano to spit lava
What causes magma in the sun?
There is no magma in the sun. The sun is much hotter than magma. At the sun's core hydrogen atoms fuse together to form helium, releasing enormous amounts of heat which causes the sun to glow brightly.

Basaltic magma is hotter than andesitic magma.
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.
Does cooler magama flow more or less quickly than hotter magma?
Cooler magma flows slower than hotter magma.
Does cooler magma flow more or less than hotter magma?
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
What is the difference in silica content and viscosity between light-colored 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.

Is magma hotter than fire?
Many will assume that lava is hotter. It may be hard to believe, but fire can generally get hotter. I guess that lava may be seen as wore due to the fact that it can smother.
How does solid rock usually become magma?
As rock is pushed down toward the the Earth's center it gets hotter and hotter.
