A magma containing not much silica (= SiO2). For example: a basaltic magma.
These magma's have a low viscosity since the lower the SiO2-content, the lower the viscosity; and hence flow easily (↔ a felsic magma).
Silicic magma is term used to describe magma with a high silica content. The higher silica content makes the magma more viscous and traps gases. Volcanoes with silicic magma tend to have much more violent eruptions. Think Mt. St. Helens (silicic) vs. Mt. Kilauea (Basaltic).
Silicate magma is magma with high levels of silica in it. Silica is found in the Earth's crust and often mixes with magma.
Molten rock under the surface is called "magma". When magma reaches the surface it is called "lava".
This is called the magma chamber.
Magma is a type of molten rock underground. Hope this helps. :)
When cool magma sinks and warm magma rises, yes that is convection.
magma turns into lava.
An acid magma or a granitic magma.

In a magma chamber
No. Magma is not alive.
No. Magma is not an ore.
The molten rock inside the Earth is called magma. When magma reaches the surface, it is called lava.
