Magma
- 1. JOHN FLORENTINO E.ECHON
- 2. Factors that affectthe viscosity of Magma 1. Temperature 2. Chemical composition/ silica content 3. Amount of dissolved gasses
- 3. 1. Temperature The viscosityof magma decreases with temperature. The higher the temperature of magma is, the lower is its viscosity. As lava flows, it cools and begins to harden, its ability to flow decreases and eventually it stops.
- 4. 2. Silica Content Magmaswith high silica content are more viscous than those with low silica content. The magma that contains less silica is relatively fluid and travels far before solidifying.
- 5. 3. Amount ofGases Other factors being equal, gas (mainly water vapor) dissolved in magma tends to increase its ability to flow. Therefore, in near-surface environments, the loss of gases makes magma more viscous, forming a dome or a columnar
- 6. Viscosity of Magmain Different Conditions
- 7. Lava with lesssilica content has low viscosity that it can travel a great distance, forming a thin sheet. 1
- 8. Lava with highsilica content is too viscous to travel far, and tends to break up as it flows. 2
- 9. Lava with lowamount of gas and high silica content is very viscous and does not flow out at all as it rises forming, a columnar plug in the vent. 3
- 10. Lava with lowamount of gas as it rises has high viscosity that it piles up at a vent resulting in a dome. 4
- 11. 1-2 Classification ofvolcanoes according to its eruption 3-5 Classification of volcanoes according to its shape 6-8 Factors that affect the viscosity of magma 9. Mayon volcano is an example of _______________ cone volcano. 10. It refers to molten rock
- 12. 11. The higherthe temperature the _________ viscosity. 12. The higher the silica content the ____________ viscosity. 13. The ______ amount of gases the higher the viscosity. 14. The ________ temperature the higher the viscosity. 15. The higher the amount of gas the _________ viscosity.
- 13. 16-17 two characteristics Lavawith less silica content has low viscosity that it can travel a great distance, forming a thin sheet. 1
