ACTIVE MAGMA VOLCANO VOLCANO 01 02 03 A volcano with accounts of The liquid rock below the A mountain or hill, typically eruption documented Earth's surface conical, having a crater or within 10,000 years (2 vent through which lava, words) rock fragments, hot vapor and gas is being or have been erupted from the earth's crust  EARTH SCIENCE Volcanoes  Objectives 01 02 03 Describe the distribution of Relate the distribution of Locate areas in the country active volcanoes to Plate active volcanoes to Plate that are prone to natural Tectonic Theory. Tectonic Theory. disaster like volcanic eruptions Volcano Volcanoes are openings, or vents where lava, tephra (small rocks), and steam erupt onto the Earth's surface. In the Philippines, there are active, inactive, and potentially active volcanoes.  earth LITHOSPHERE – composed of crust and upper mantle. TECTONICS – movement of the lithosphere  earth According to the Plate Tectonics Theory, the entire lithosphere of the Earth is broken into numerous segments called plates. 01 02 SEATWORK #1 1.

The crust and upper mantle make up Earth’s __________. A. Asthenosphere B. Continents C. Core D. Lithosphere 5. Which statement does best describe the location of the majority of earthquake epicenters relative to the location of volcanoes around the world? A. They are far adjacent. B. They are always 3 kilometers away from each other. C. They are situated at the same location. D. They are not necessarily relevant.  Additional Activity Re-think the risks  What you need One whole and ball pen Philippine geographic/political map  What you have to do 1. Look at the Philippine map. Can you pinpoint where you are now? 2. Study the hazard maps that will show you areas in our country that are prone to natural disasters like volcanic eruptions. (soft copies will be provided by the teacher) 3. Look at the geographical or political map of the Philippines. Try to compare the areas provinces with darker colors. These are the high-risk areas to the volcanic eruptions. 4. Get a whole sheet of paper for your answers and observations. (copy and answer) a. Which regions are high-risk (darkest shade), medium and low-risk in terms of volcanic eruptions? b. If you will choose a province to live, where will it be? Why? Thank You!
