How does the viscosity affect of lava affect its flow rate?
Viscosity means how runny it is. Thus a lava with low viscosity will erupt fast and form long, wide spreading lava flows (eg Hawaii) and lavas of high viscosity will erupt slowly and form lava domes (eg Mt. St. Helens).
What is lava called with high viscosity?
Lava with high viscosity is called slica-rich lava
Does crystal content affect viscosity of lava?
Yes, the more numerous and larger the crystals are, the more viscous the lava is: it does not, however, have a very dramatic effect.
Does High viscosity lava flows faster than low viscosity lava?
No. Viscosity is a liquid's resistance to flow. So higher viscosity means a slower flow.
Is pyroclastic material likely to form from low-viscosity lava or high-viscosity lava?

How would viscosity of the lava affect the size of the crystals that forms in the rock as it cools?
If the lava has cooled fast, the Cristal's will be smaller. If the lava cooled slowly, the crystals will be big

Yes, the more numerous and larger the crystals are, the more viscous the lava is: it does not, however, have a very dramatic effect.
How does the thickness of lava affect nature?
Its viscosity affects the speed of its flow. If it had a low viscosity, then its flow would be much faster and hence more menacing to the environment.
How does the silica content of lava impact its viscosity?
Silica content is directly proportional to viscosity, so the higher the silica content of a lava, the higher its viscosity. high viscosity means a lava will be thick and slow moving, hence probably meaning an explosive eruption. lava's with a high viscosity include rhyolite and andesite whereas lava's with a low viscosity (runny ones) include basalt.
Does High viscosity lava flows faster than low viscosity lava?
No. Viscosity is a liquid's resistance to flow. So higher viscosity means a slower flow.
Is pyroclastic material likely to form from low-viscosity or high-viscosity lava?
low viscosity lava due to the violent eruption of the volcano

What kind of viscosity lava does Mount Tambora have?
High viscosity.
Does sugar affect the viscosity of water?
Yes
Does Krakatoa make pillow lava?
No. Pillow lava is basaltic, low-viscosity lava. Krakatoa is a stratovolcano with a style of ereuption more characteristic of high-viscosity andesitic lava.
