Rock begins to melt when?
When the temperature reaches the lowest melting point of the mineral or minerals of which the rock is made.That depends entirely on what type of rock you have, and what it's made up of. Different substances have different melting points. Igneous rock has the highest, which means they don't melt easily. You'd have to know what types of materials are in the rock and look up their respective melting points in a chemistry book, or online. There is no one single answer to your question.
What does the temperature have on the characteristics of magma?
Temperature, among other factors, effects the viscosity(thickness) of magma. However, for the most part, the temperature of magma is relatively consistent because magma is the type of molten rock that has not yet exited the volcano, so there are fewer factors to effect the temperature.
Which factors determine how violent an eruption will be?
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
What type of magma that tends to cause explosive eruptions has a what?
High temperature
What types of molecules would have the lowest melting point?
Type your answer here... Nonpolar molecules
Which type of magma is produced at the Coolest temperature?
felsic magma
What is the melting point of magma?
Temperatures of most magmas are in the range 700 °C to 1300 °C (or 1292 °F to 2372 °F), but very rare carbonatite melts may be as cool as 600 °C, and komatiite melts may have been as hot at 1600 °C

What type of crystaline solid has the lowest melting points?
These are solids with covalent bonds.
What affects the type of igneous rock that is formed?
Mineral composition of the magma, Rate of cooling of the magma, Temperature of the magma, Presence of volatiles and Amount of water present in the magma.

What type of rock is made from magma cooling?
If a magma of higher temperature cools down, certain minerals solidify first. Eventually, those minerals that remain liquid at the lowest temperatures solidify the latest. The rock that is then formed is Granite (if it's intrusive), or Rhyolite (if it's extrusive)
What does more iron and magnesium make magma?
More iron and magnesium in magma can make it more dense and viscous. This can result in a thicker magma that is less likely to flow easily. It may also affect the melting temperature and can influence the type of volcanic eruptions that occur.
