Question

For each of the statements below, choose "silicic magma" or "mafic magma" or neither.

As a lava, could easily flow great distances from a volcanic eruptive center because its viscosity is so low.

Creates explosive volcanic eruptions because of a high volatile content.

Typically behaves as a highly viscous or thick fluid.

Begins to melt at about 1000°C.

Begins to melt at about 800°C.

Quartz is a main mineral in the igneous rock that forms from this magma.

Has a silica (SiO2) content of 48%.

Forms dark colored volcanic or plutonic igneous rocks.

Quartz is not a main mineral in the igneous rock that forms from this magma.

Quartz and olivine both occur as main minerals in the igneous rock that forms from this magma.

Creates explosive volcanic eruptions because of a high volatile content.

Typically behaves as a highly viscous or thick fluid.

Begins to melt at about 1000°C.

Begins to melt at about 800°C.

Quartz is a main mineral in the igneous rock that forms from this magma.

Has a silica (SiO2) content of 48%.

Forms dark colored volcanic or plutonic igneous rocks.

Quartz is not a main mineral in the igneous rock that forms from this magma.

Quartz and olivine both occur as main minerals in the igneous rock that forms from this magma.

1. Silicon magma creates explosive volcanic eruptions because of a high volatile content.

2. Silicic magma has high

3. Neither

4. Quartz is a essential mineral in Silicic magma.

5. Neither. Because it is intermediate magma

6. Magic magma forms dark colored volcanic or platonic igneous rocks.

6. Silicic magma

7. Neither. Because quartz and olivine never occur together.
