A. Differentiate the following: 1. earthquake's magnitude and intensity 2. earth's Crust, mantle and core 3. magma and lava 4. Philippines dry and wet season 5. Earth's rotation and revolution 6. PAGASA and PHILVOLCS
Answer (1)
Earthquake’s Magnitude vs. IntensityMagnitude measures the total energy released at the earthquake’s source and is recorded using the Richter scale. It remains constant regardless of location.Intensity describes the earthquake’s effects on people, structures, and the environment, varying based on distance from the epicenter. It is measured using the Modified Mercalli Intensity (MMI) scale.Earth’s Crust, Mantle, and CoreCrust: The outermost and thinnest layer of the Earth where we live. It consists of solid rock.Mantle: The thickest layer, located beneath the crust, composed of semi-molten rock (magma). It drives plate tectonics.Core: The innermost layer, divided into a solid inner core (iron and nickel) and a liquid outer core, responsible for Earth’s magnetic field.Magma vs. LavaMagma is molten rock stored beneath the Earth's surface.Lava is magma that has erupted from a volcano onto the Earth's surface.Philippines' Dry vs. Wet SeasonDry Season: Occurs from November to May, bringing little rainfall and higher temperatures. It is divided into the cool dry season (November–February) and hot dry season (March–May).Wet Season: Lasts from June to October, characterized by frequent rainfall and typhoons due to the southwest monsoon (Habagat).Earth’s Rotation vs. RevolutionRotation: The Earth spins on its axis, taking 24 hours, causing day and night.Revolution: The Earth orbits the Sun, taking 365.25 days, resulting in the changing seasons.PAGASA vs. PHIVOLCSPAGASA (Philippine Atmospheric, Geophysical, and Astronomical Services Administration) monitors weather, climate, and typhoons in the Philippines.PHIVOLCS (Philippine Institute of Volcanology and Seismology) focuses on earthquakes, volcanoes, and seismic activities to ensure disaster preparedness.
