- 2. Rock Cycle is abasic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous.
- 3. Rock Cycle 1. MAGMATISM 2.MAGMA 3. LAVA 4. OXYGEN 5. BASALTIC MAGMA 6. RHYOLITIC 7. ANDESITIC 8. HIGH TEMPERATURE 9. IGNEOUS ROCK 10. IN SUBDUCTION ZONE
- 4. From Molten Materialsto Rocks Metamorphic rocks formed when preexisting rocks are exposed to high temperature and pressure but remain solid. However, when they subjected to extreme pressure and temperature, melting occurs. This produces molten rocks called magma. The molten rocks that have crystallized become igneous rocks.
- 5. Activity 1: PictureAnalysis Observe the picture of Mount Mayon and answer the following: Give three (3) descriptions about the picture. What is the material being extruded by Mount Mayon? Where do you think did this material come from?
- 6. What is Magma? Magmais composed of semi- liquid hot molten rocks located beneath the Earth, specifically in the melted mantle rock and oceanic plate. This molten state, when solidified, creates igneous rocks found on the surface of the Earth.
- 7. What is Magma? Magmaand lava are both molten rocks. However, they differ in location. Magma is found inside the magma chamber of the volcano while Lava is found on the surface of earth once the volcano erupts.
- 8. What is Magmatism? -isa process under the earth’s crust where formation and movement of magma occur. -These happen in the lower part of the Earth’s crust and in the upper portion of the mantle, known as asthenosphere.
- 9. Composition of Magma GuideQuestions: 1. Which of the following elements has the highest amount in the magma? 2. Which of the following elements has the lowest amount in the magma? 3. What are the top two compositions of magma?
- 10. THREE TYPES OFMAGMA 1. Basaltic Magma- it is the most common magma on earth. It is characterized by its low silica content, high temperature, low viscosity, and low gas content
- 11. THREE TYPES OFMAGMA 2. Rhyolitic Magma- has high silica content, low temperature, very high viscosity and high content of gas
- 12. THREE TYPES OFMAGMA 3. Andesitic Magma- a magma with the properties of that are between basaltic and rhyolitic magma
- 13. The magma presentin the lower crust and upper mantle of the Earth is formed or generated through the process of partial melting. In this process, different minerals in rock melt at different temperature and pressure. How is Magma formed?
- 14. Another factor beingconsidered in this process is the addition of volatile materials such as water and carbon dioxide.. How is Magma formed?
- 15. How is Magmaformed?
- 17. Melting in themantle requires one of three possible events to occur: 1. AN INCREASE IN TEMPERATURE: Conduction in mantle happens when heat is transferred from hotter molten rocks to the Earth’s cold crust. This process is known as heat transfer. It happens at convergent boundaries, where tectonic plates are crashing together.

- 19. Melting in themantle requires one of three possible events to occur: 2. A DECREASE OF PRESSURE: Mantle rocks remain solid when exposed to high pressure. However, during convection, these rocks tend to go upward and the pressure is reduced. This triggers the melting of magma. This is known as decompression melting. This process occurs at the Mid-Ocean Ridge, an underwater mountain system.

- 21. Melting in themantle requires one of three possible events to occur: 3. ADDITION OF VOLATILES: When water or carbon dioxide is added to hot rocks, flux melting occurs. The melting points of minerals within the rocks decrease. If a rock is already close to its melting point, the effect of adding these volatiles can be enough to trigger partial melting. It occurs around subduction zones.

- 23. VOLCANISM It refersto the processes and phenomena associated with the eruption of (molten magma) The eruption of molten rock from inside the Earth to the surface. It’s occurring because of Earth’s internal heat, and is associated with tectonic processes and a part of rock
- 24. Three Types ofRocks IGNEOUS ROCKS formed from hardening and crystallization of magma or molten material that originates deep within the earth. Latin (ignis) means fire
- 25. Three Types ofRocks IGNEOUS ROCKS - Crystallization- is the process of the formation and growth of individual mineral crystals.
- 26. Two types ofIgneous rock A. Extrusive/Volcanic rock - forms when magma makes its way to Earth’s surface as lava and then cools. The crystals are very small (fine grained) since the cooling process is fast.
- 27. Two types ofIgneous rock B. Intrusive/Plutonic - It cools slowly beneath the Earth surface and are created by magma. The intrusive igneous rocks have very large crystals (coarse grained).
- 28. Classification of Igneousrock 1. Composition FELSIC - light in color; feldspar and silicates MAFIC - dark in color; made up of magnesium and iron INTERMEDIATE – between mafic and felsic ULTRAMAFIC - very dark color
- 29. Classification of Igneousrock 2. Texture- overall appearance of rock Aphanitic - fine grained Phaneritic- coarse grained Porphyritic- large crystals with small crystals Glassy- non-ordered solid from rapid quenching Pyroclastic- composite of ejected fragments
