Outer - second 4. Inner - third Volcanology: study of volcano Meteorology: the study of Weather and Climate 1. Troposphere - lowest layer 2. Stratosphere - where aircrafts were 3.

Seismograph: used to measure earthquakes Phillipines is a tropical climate. Lesson 2: Earthquake - sudden movement of the ground PHILVOCS ( Phillipine Institute of volcanology and seismology ) - a government group/ an agency 2 Volcano classification. - active ( a volcano that has a record of an eruption in 600-10000 years) - inactive ( If not ) PARTS OF A VOLCANO EXTERNAL 1. Base - lowest part 2. Slope - the steep part ( center ) 3. Summit - most external INTERNAL 1. Magma Chamber - the reservoir (Storage) of the lava, Beneath the Earth's surface is called magma ( Hot molten Rocks )... 2. Vent - passageway of the magma to outside of the volcano.. 3. Crater - The very opening / the mouth of the volcano. / A funnel-shaped opening at the top of the volcano. 4. Pyroclastic ash - Gas given off when the volcano erupts. 5. Lava - hot melted rocks and given off when volcano erupts. - becomes part of the volcano once solidified - depending on the types of volcano the lava takes different forms Cadera - the baon in the crater / deformed of the volcano's crater. / Water also forms when / opening in the crater. Metamorphic - diamonds/crystals Igneous rocks - rocks that solidified / also know as the fire rocks Sedimentary - sand Lesson 3: TYPES OF VOLCANIC ERUPTIONS FACTORS AFFECTING THE VOLCANOES' ERUPTIVE STYLE • Magma's Viscocity • property of materials resistance to flow • describe as liquids thickness and stickiness 1. Magma's Temperature - High temperature less viscous, less temperature more viscous. 2. Chemical Composition - high silica more viscous, less silica less viscous. • Lava with less silica has low viscosity that it can travel in a great distance forming a thin sheet. 3. Amount of Gases Dissolve - Less gases more viscous, high gases less viscous. • lava with low amount of gas and high silica content is very viscous and does not flow out at all as it rises, forming a columnar plug in vent. • lava with low amount of gas as it rises has a high viscosity that it piles up at the vent resulting in a dome. Types of volcanoes, 1. Phreatic or hydrothermal - steam based explosion, aqua and hot rocks 2. Phreatomagmatic - reaction by aqua and magma 3. Strombolian - Fountain lava 4. Vulcanian - tall pyroclastic ash 5. Plinian - Most explosive, excessive type Geothermal energy - an alternative source of energy that generates electricity which is the source using the heat beneath the ground Geo - 'Earth'
