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.

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!
