Question

For each of the statements below, choose "silicic magma" or "mafic magma" for the kind of magma that best matches the statement.

Has a silica (SiO2) content of 48%.

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

Begins to melt at about 1000°C.

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

Begins to melt at about 800°C.

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

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

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

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

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

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

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

Typically behaves as a highly viscous or thick fluid.

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

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

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

Creates explosive volcanic eruptions because of a high volatile content.

[ Choose ] silicic magma mafic magma neither silicic nor mafic magma

Forms dark colored volcanic or plutonic igneous rocks.

1. Has a silica (SiO2) content of 48%. - Mafic Magma

2.Begins to melt at about 1000°C. - Mafic magma

3. Begins to melt at about 800°C. - Silicic Magma

4.Quartz is a main mineral in the igneous rock that forms from this magma.- Silicic Magma

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

6. Quartz and olivine both occur as main minerals in the igneous rock that forms from this magma. - neither silicic nor mafic magma

7. Typically behaves as a highly viscous or thick fluid. - Mafic Magma

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

9. Creates explosive volcanic eruptions because of a high volatile content. - Silicic Magma
