Science Science QE QE reviewer reviewer “The Crust” The crust is the outermost layer of the Earth. Least dense due to lighter rock material. Divided into 2 parts. Continental Oceanic Thicker Thinner Less dense More Dense Partial melting over time = Partial melting at mid- less dense rocks oceanic ranges “The Mantle” The mantle makes up 80% of the Earth. Thermal convection The cycle of heating, rising, cooling, & sinking of rock materials. Subduction An edge of a crustal plate subducts/descends  “The Core” The core is the most dense layer of the Earth. Has the highest temperature and pressure. Inner and Outer core Inner core = solid, Outer core = liquid Inner core = 4000-5000C, Outer core = 5000-7000C Lesson 1: distribution of earthquakes, volcanoes and mountain ranges “The pacific ring of fire” “Earthquake belt” “Volcanic belt” “!ALFRED WEGNER!” first proposed the theory of continental 🗣️🔥💯 drift in 1912 (the G.O.A.T ) “Continental Drift Theory” movement of lithospheric plates that interact slowly with underlying mantle Earth’s lithosphere is broken into plates  Lesson 3: Departments that help with typhoon damage Philippine Atmospheric, Department of Social Welfare Geophysical Astronomical and Development (DSWD) Association (PAGASA) -plays a crucial in providing immediate -provides weather forecasts and assistance to those affected by warnings disaster Philippine Institute of Department of Interior and Volcanology and Seismology Local Government (DILG) (PHIVOLCS) -ensures that local government units -monitors volcanic activity, earthquakes, have the necesary resources and and tsunamis training to manage disasters Philippine National Police Department of (PNP) Health (DOH) -their units are deployed to areas -coordinates health facilities to assist affected by disasters to provide local governments in disasters assistance, enforce evacuations, etc. Bureau of Fire Protection (BFP) -provide medical care, start search Department of Public and rescue operations after disaster Works and Highway (DPWH) -restores and clears vital access roads, National Economic and bridges, and reconstructing Development Authority infastructures (NEDA) -leads rehabilitation and recovery, and advocates for proper preparation to National Disaster Risk disasters Reduction Management Council (NDRRMC) -main government body in charge of coordinating disaster risk management Department of National efforts Defense (DND) -responsible for disaster preparation and management, and is involved in disaster responses  Lesson 4: What is a typhoon and how is it formed? “Typhoons, Hurricanes, and Cyclones” “Typhoon formation” Starts off as a tropical storm. Strong winds reel in moisture. Converts moisture into heat. Heat causes more air to go to the center for evaporation All the heat and air go to the center making the eye of the storm  Lesson 5: Parts of a typhoon “Eye of the storm” Calm, low pressure area in the center of the storm 20 to 40 kilometers in diameter “Eye wall” Highest windspeeds, heavy rainfall, turbulent clouds. It’s rotation is what gives the typhoon it’s destructive power.  “Rainbands” Spiraling bands of clouds. Extends outwards from the eyewall Heavy rains, strong winds and sometimes tornadoes. Lesson 6: tropical cyclone warning signals Lesson 7: heavy rainfall warning signals 1.
