Earth and Space Science
- Plate Tectonics Theory: Proposes the Earth's lithosphere is composed of plates.
- Evidence Supporting Plate Tectonics:
- Fossil distribution: Similar fossils found in different locations.
- Earthquake and volcano locations: Clustered at plate boundaries.
- Geological Features: Activities occur along boundaries.
- Spreading seafloor: Molten material causes plates to move apart.
- Plate Boundaries: These are locations where plate interactions cause geological activity.
- Convergent Boundaries: Plates move toward each other.
- Types include fold mountains, deep-sea trenches and volcanic mountains.
- Resulting movement is destructive.
- Continental-Continental: Neither plate sinks.
- Continental-Oceanic and Oceanic-Oceanic: Denser oceanic plate sinks.
- Divergent Boundaries: Plates move away from each other.
- Types include mid-ocean ridges and rift valleys
- Resulting movement is constructive.
- Transform Boundaries: Plates slide past each other.
- Types include major earthquakes.
- Resulting movement is conservative.
- Volcanoes:
- Types (Structure):
- Cinder Cone (e.g., Taal) – Piles of lava
- Composite/Stratovolcano (e.g., Mayon) – Alternating layers of lava and ash.
- Shield (e.g., Mauna Kea) – Outpourings of lava
- Types (Activity):
- Active – Erupted within last 10,000 years.
- Potentially-Active – Young looking, no recent eruption records
- Inactive – Not erupted in last 10,000 years.
- Types (Structure):
- Volcanic Eruptions: Magma's temperature, viscosity, silica content, amount of dissolved gases are factors that affect eruptions.
- Types: Phreatic, Phreatomagmatic, Strombolian, Vulcanian, Plinian
- Volcanic Hazards: Lava flows, tephra falls, pyroclastic density currents (PDCs).
- Energy from Volcanoes: Hot water from volcanic activity can be converted to steam to generate electricity.
- Climate Factors: Latitude, altitude, distance from sea, topography regulate climate.
- Climate Phenomena: Global Warming, El Niño, La Niña.
- Indicators of Climate Change: Rising temperatures, sea levels, melting ice caps.
- Practical Ways to Mitigate Climate Change: Reduce, reuse, recycle, eat vegetables, save energy.
- Stars and Constellations:
- Stars are massive balls of gas (Hydrogen and Helium).
- Movement of Stars: Earth's rotation and revolution affect star visibility.
- Beliefs and Practices about Constellations: Astrology and Indigenous practices like using constellations for navigation.
- Galaxies: Composed of Hydrogen, Helium, oxygen and Carbon.
- Types: Spiral, Elliptical and Irregular.
- Components: Disk, bulge.
