At the end of the lesson, the learners will be able to: 1. describe the characteristics of magma; 2. identify the substances/elements present in magma; 3. explain the processes involved in the formation of magma; and 4. give importance on how the formation of magma affects the environment.

Picture Analysis
Video Analysis Guide Questions: 1. Give three (3) descriptions about the picture. 2. What is the material being squeeze out by Mount Mayon? 3. Where do you think did this material come from? https://www.youtube.com/shorts/2n2WqUW_DJs
MAGMA vs LAVA MAGMATISM What is MAGMA? A semi-liquid hot molten rocks located beneath the Earth https://scitechdaily.com/global-cooling-13000-years-ago-was-caused-by-volcanic-eruptions-not-meteors/
What is MAGMA? Magma is a molten rock; located at the magma chamber of the volcano Lava is a molten rock; located at the surface of the Earth once volcano will erupt MAGMA vs LAVA MAGMATISM
What is MAGMA? MAGMA vs LAVA MAGMATISM The process under the Earth’s crust where formation and movement of magma occur. This happens in the ASTHENOSPHERE
ASTHENOSPHERE Composition of magma How is magma formed? the lower part of the Earth’s crust and upper portion of the mantle. https://gifer.com/en/gifs/convection
ASTHENOSPHERE Composition of magma How is magma formed? https://study.com/learn/lesson/asthenosphere- temperature-facts-density.html
ASTHENOSPHERE How is magma formed? Composition of magma https://opentextbc.ca/physicalgeology2ed/chapter/3-2-magma-and-magma-formation/
ASTHENOSPHERE Composition of magma How is magma formed? Through PARTIAL MELTING Partial melting forms the magma present in the asthenosphere
Increased temperature Addition of Volatiles Decrease of pressure PARTIAL MELTING
Increased temperature Addition of Volatiles Decrease of pressure PARTIAL MELTING
Addition of Volatiles Decrease of pressure Increased temperature PARTIAL MELTING
Addition of Volatiles Decrease of pressure Increased temperature PARTIAL MELTING
1. Do you think partial melting will occur if the pressure is high in the asthenosphere? 2. Do you think partial melting will occur if there is too much amount of water in the subduction zone? 3. Do you think partial melting will occur if there is direct contact of hot molten rock in the Earth’s crust?
How does the formation of magma affect the environment?
ACRONYM! Directions . Use the word MAGMATISM as an acronym. Use each letter to represent word/s that is related to the lesson
Additional activities Directions. Read the poem below and answer the question that follows. Magma by Jemie Ann A. Quiroba ( Mataas na kahoy Senior High School) HUMSS 12 SY 2019-2020 I kept myself I hid to deep Burned myself, with my own heat I must go out, must go with the flow My red tears shouted pain, as it glows So as I am, later on it would be tough I freed my burning self and I'll go reach the top Answer: What is the message of the poem?
