By GROUP 1  WHAT IS MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma WHAT IS WHAT IS MAGMA? MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma WHAT IS MAGMA? Magma comprises semi-liquid hot molten rocks located beneath the Earth, specifically WHAT IS in the melted mantle rock and oceanic plate. MAGMA? This molten state, when solidified, creates igneous rocks found on the surface of the Earth. At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  LAVA Lava is found Magma is MA on the surface found in the of the Earth WHAT IS magma when the MAGMA? chamber of volcano the volcano erupts. Magma comprises semi-liquid hot molten rocks located beneath the Earth, specifically Atin thethe endmelted mantleyou of this lesson, rock are and oceanic expected to: plate. This molten state, when solidified, creates Describe the characteristics of magma; Identify the substances present in igneous magma; rocks and found on the surface of the Explain the processes involved in forming Earth. magma MAGMATI WHAT IS MAGMA? SM At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma MAGMATI SM Magmatism is a process under the Earth’s WHAT IS crust MAGMA? where formation and movement of the magma occur At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  WHAT IS MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma HOW IS MAGMAWHAT IS MAGMA? FORMED? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma HOW IS MAGMA FORMED? Partial melting is the process WHAT IS where different minerals MAGMA? in rocks melt at different temperature and pressure At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  Potassium - 2.6% Sodium - Magnesium - Calcium - 3.6% 2.8% Others 2.1% Oxygen - 46.6% Iron - 5% Aluminum - 8.1% Silicon - 27.7% WHAT IS MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  WHAT IS MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma MANTLE MELTING OCCURS DUE TO WHAT IS ONE OF THREE MAGMA?EVENTS: At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma TEMPERATURE INCREASE Conduction in the mantle happens when heat is transferredWHAT from hotter IS molten rocks to the Earth’s cold crust, this process is MAGMA? known as heat transfer. This process happens at convergent boundaries, where tectonic plates are crashing together At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  WHAT IS MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma TEMPERATURE INCREASE The temperature of the mantle is around WHAT IS 1200℃. Rock MAGMA? minerals such as quartz and feldspar begin to partially melt at around 650-85 ℃ At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma TEMPERATURE DECREASE During convection, rocks tend to go upward and pressure WHAT ISis reduced, this triggers the melting of the magma. This MAGMA? process is called decompression melting and occurs at the mid-ocean ridge. At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  WHAT IS MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  ADDITION OF VOLATILES When water or carbon dioxide is added to hot rocks, flux melting occurs. The melting WHAT IS points of minerals within the rocks decrease. MAGMA? If a rock is already close to its melting point, the effect of adding these volatiles can be enough to trigger partial melting. This occurs at subduction zones. At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma  WHAT IS MAGMA? At the end of this lesson, you are expected to: Describe the characteristics of magma; Identify the substances present in magma; and Explain the processes involved in forming magma
