Picture Analysis. (presentation of different volcanic emissions) D. Presenting examples / instances of the new lesson What can you observe from these pictures? Do you know what these are? Can you name one of these pictures? From this analysis, can you guess what From the pictures could be our lesson all about? presented, I think our topic for today’s discussion is related with the volcanic emissions. What are the products of volcanic eruptions class? Volcanic eruptions E. Discussing new produce three types of concepts and materials: volcanic gas, practicing new lava, and fragmented skills #1 Volcanic gases are ejected by active debris called tephra. volcanoes. These include dissolved gases in magma and lava or gases emanating from lava, gases trapped in vesicles in volcanic rocks, and even emitted by groundwater heated by volcanic eruptions. Volcanoes release gases when they erupt, and through openings called fumaroles. They can also release gas into soil and groundwater. Figure 1. Norris Basin fumaroles, https://www.flickr.com/photos/clouds 7 Yellowstone oup/383368895 As shown in the picture, the main component of volcanic gas emissions is water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide. What is again a lava, class? Any idea about it? Lava is a molten rock(magma) that is ejected out from the interior of the earth. The ease with which lava flows and the structures it forms depends on how much silica and gas the lava contains. A lava flow is a moving outpouring of lava created during a non-explosive effusive eruption. The following are the lava flow materials and pyroclastic materials that are ejected from the opening of volcanoes. Here are the following lists of various volcanic material with their definitions. Please read what is a lava flow materials? Lava Flow Materialsare a stream of molten rock that erupts relatively nonexplosively from a Thank you, class. So these are the following lava flow materials. What are these, class? volcano and moves slowly downslope. A. Aa:: Aa (pronounced "ah-ah" - a Hawaiian term), is lava that has a rough, jagged, spiny, and generally clinkery surface. B. Pahoehoe: Pahoehoe (pronounced "pah-hoyhoy" - a Hawaiian term), is a very fluid lava flow, solidified that in form, is characterized by a smooth, billowy, or ropy surfaces. C. Lava: The term used for magma once it has erupted onto the Earth's surface. We move with the other materials that are ejected from the explosion. These are the pyroclastic materials. These pyroclastic materials pertain to fragmented rock material formed by a volcanic explosion or ejection from a volcanic vent. a. Volcanic Ash: Fragments less than 2 millimeters in diameter of lava or rock blasted into the air by volcanic explosions. b. Blocks:: Fragments of lava or rock larger than 64 millimeters in size that are blasted into the air by volcanic explosions. c. Bombs: Fragments of fluid or partially fluid lava or rock larger D. Pillow Lava: A special structure of fluid lava erupted or flowing underwater. than 64 millimeters in size that are blasted into the air by volcanic explosions. d. Cinder:: Cinders are vesicular lava fragments 1 centimeter or larger in diameter. e. Lapilli: Fragments of lava or rock between 2 and 64 millimeters in size that are blasted into the air by volcanic explosions. e. Pumice:: A light-colored, frothy, vesicular volcanic rock, usually of intermediate and composition, formed felsic by the expansion of gas in erupting lava. f. Scoria:: A dark to reddishcolored, scoriaceous, vesicular volcanic rock, usually of mafic composition. g. Tephra:: Solid material of all sizes explosively ejected from a volcano into the atmosphere. The following pictures are some of the lava and pyrocrastic flows. Please study these pictures and take note of the different styles of these materials. As we can see, there are also types of rocks in the pictures presented. How do you think do volcanic eruptions affect our society? Any idea about this, class? A volcanic eruption is often associated with both positive and negative effects. Our planet, the Earth is active, geologically speaking and as such, it undergoes a process of constant renewal by way of volcanic eruptions. Volcanoes erupt when magma reaches the surface due to high pressure and starts to pool in a magma chamber. Apart from enhancing soil fertility, the resultant eruption also helps to bring out various precious minerals buried deep in the earth such as Diamond, Opal, Garnets, emeralds and much more. Volcanoes can provide you with a ready source of power since the same can be tapped by geothermal power stations and help to power up the various cities located close by. A good example of the eruption is the Pinatubo Volcano which created a spectacular view resulting in an income generation of the community that attracts lots of tourists. Figure 3. Pinatubo Crater Lake https://www.flickr.com/photos/davedeluri a/150988141 The lava that blasted from the eruption makes the soil fertile, but this can be done after years of eruption. All volcanic eruptions result in widespread damage to the point that whole cities are destroyed along with the entire local infrastructure. This can impact the local population on several levels, and it can take a while before the city can be reconstructed. It can cause loss of lives and properties. Even though a volcanic eruption leads to increased fertility in the soil, the process takes time. Meanwhile, the fall out on the local environment is immediate with ash, toxic gases all of which impact the local flora and fauna. CLASSIFY ME! To check your comprehension to our lesson. I want you to answer this one individually in a ¼ sheet of paper. Classify the effects of volcanic eruption if it is positive or negative effects. Write positive if the statement says positive effect, and write negative if it is otherwise. F. Developing Mastery (Leads to Formative Assessment 3) 1. It can cause loss of lives and properties. 1. NEGATIVE 2. It serves as a tourist spot. 2. POSITIVE 3. Volcanic eruptions can cause a 3. NEGATIVE decrease in the Earth’s surface 4. NEGATIVE temperature. 5. NEGATIVE 4. As lava flows or pyroclastic materials are 6. NEGATIVE ejected in the air, they can destroy anything 7. NEGATIVE 8. POSITIVE on their way. 5. The strong winds during its eruption spread 9. POSITIVE 10. POSITIVE the aerosol particles from the plume around the globe. The measurable cooling of the Earth’s surface for a period for almost two years. 6. It can cause loss of infrastructures. 7. There will be the destruction of crops. 8. It produces very rich soils for farming. 9. People became creative also by making earthenware out of the ashfall. 10. It helps us to know what’s inside the Earth. G. Finding practical application of concepts and skills in daily living These identified Recognize the importance of identified personnel like those of authorities (DRRM) to the safety of people in DRRM/PHIVOLCS help volcanic eruptions. people to evacuate. They also announce and update what are the things we should do before, during, and after a volcanic eruption. In this case, people will be alarmed to evacuate and prepare for the effects and damages a volcanic eruption might bring to society as well as the human being. Very good! Any other answers, class? So these authorized personnel together with the PHIVOLCS announce updates about what to do, what to expect and what are the preparations that people should do in this times of phenomenon. Identify the effects of a volcanic eruption. Choose ✔ inside the box if it is an effect of volcanic eruption and X if not. H.
