Study Notes
Wegener's Continental Drift Theory
- Wegener suggested that the drifting of continents was responsible for the breakup of the supercontinent Pangaea.
Oceanic Tides
- The major cause of tides in oceanic waters is the gravitational pull of the Moon and the Sun.
Plate Boundaries
- Divergent boundaries occur when plates move apart, resulting in the creation of new crust.
- Convergent boundaries lead to subduction zones, where one plate is forced under another.
Tectonic Plates
- The Philippines plate is considered a minor plate in terms of area size.
- The Pacific plate is the largest in terms of area.
Plate Tectonics Theory
- The main idea behind the theory of plate tectonics is that the Earth's lithosphere is broken into plates that move relative to each other.
Plate Composition
- Oceanic plates are composed mostly of magnesium and silicon minerals.
- Continental plates are made up of continental crust rich in aluminum and silicon materials.
Evidence for Continental Drift
- Evidence supporting the Continental Drift theory includes fossil evidence, similar rock formations, and glacial deposits.
- A characteristic feature of tillite is that it is a type of sedimentary rock formed from glacial deposits.
Non-Evidence for Continental Drift
- The Earth's rotation is not a piece of evidence supporting the Continental Drift theory.
