Silica is like Carbon, Basically its atoms form strong covalent bonds between each other(4 as they each have 4 electrons in their outer shell) these bonds are branched in a never ending pattern, many of these strong bonds have to be broken in order for Silica to melt and hence it has a high melting point
low melting point
This is because silica has a high melting point due to its giant molecular structure. To break it up you would have to break strong covalent si-O bonds. I stumbled across this as i was trying to do my chemistry assessment. Hope it helped :)
Yes, it has a melting point of 1683 Kelvin.
They have high melting points
ionic compound tend to have a high melting point because of their high electronegativity.
The composition of the magma is very important for solidificatoin temperature. When it starts to cool, crystals of minerals begin to grow. If it has a low silica content - which means high melting point - the magma will solidify at high temeratures. If it has a high silica content - which means low melting point - it will solidify at lower temperatures.
The melting point of silicon dioxide is in the range 1 600-1 725 0C.

it has a low melting point
All metals have different melting points but they are all high
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
High Melting Point Of Over 1000 Degrees

No, this is a low melting point.
