Why is the amount of Silica in magma important?
It is important because you can tell wether the magma is very or little bit thin and runny or very thick and very sticky.
What can cause the most explosive volcano?
If you get a very sticky magma (molten rock) which can occur due to the composition of the magma it makes it hard for gas to escape (e.g. think of blowing bubbles through honey and water, its harder through honey), when the gas does escape out of these sticky magma's it has built up a lot of pressure and explodes.
Does a volcano erupt quietly if its magma is thick and sticky?
Usually very viscous magma is rich in gasses, so it will erupt explosively, forming clouds of ash and pumice rather than lava flows. If the magma is fairly depleted in gasses then it may form a lava dome. The lava in this case is too viscous to flow away from the vent, so instead it piles up on top of it. Such domes may sometimes form thick, short lava flows called coulees.
How does the amount of silica content change the viscosity of magma How does this affect the flow of magma?
The amount of silica and water affect the viscosity of the magma. The more viscous the magma, the slower the flow rate and the shorter and the thicker the flows. Silica makes for a more viscous magma.
Is the mantle part of the earth a solid or liquid?
The mantle consists of molten rock. Therefore, it made up of a very thick, hot liquid referred to as magma.

What is Venus atmopheric conditions?
Venus is generally very hot and the atmosphere is very thick and full of clouds.
When magma does crystallization what rock does it make?
That entirely depends on what type of magma it is and under what conditions it crystallizes. If you are looking for a general rock type, the answer is igneous, but that's very general.
Are milkshakes sticky?
yes they are very sticky

Some sticky substances are yucky things?
Some sticky substances are very yucky things. Boogers are sticky and they are very nasty things. Molasses is also sticky.
Hat is the difference between cobwebs and spiderwebs?
Technically no difference. Some spider web is sticky some is not, som is very thin and some as thick as horse hair.
What will happens when you add kerosene to diesel or petrol engine?
kerosene is thick fuel. when it will pass through fuel injection left it sticky and there will be a very adverse effect on the piston.
How does the viscosity of the magma influence the type of eruption?
The viscosity of magma affects whether or not magma flows away or piles up during an eruption. Viscosity, along with volatiles (dissolved gases) and volume determine whether you have a peaceful eruption or a very violent one.
