Answer :
Final answer:
Plate Tectonics theory explains the movement of Earth's lithosphere through tectonic plates on the asthenosphere, leading to geological phenomena like mountain formation and continental drift.
Explanation:
Plate Tectonics is a theory that explains the movement of Earth's lithosphere through the motion of tectonic plates made up of the crust and upper mantle. These plates float on the flowing asthenosphere and interact at plate boundaries, leading to geological phenomena like mountain formation and continental drift.
- Tectonic Plates: These are rigid pieces of Earth's lithosphere that move independently above the mantle.
- Lithosphere: The outer rigid layer of Earth that includes the crust and uppermost mantle.
- Mantle Circulation: The circulation of molten rock in the mantle drives the lateral movement of tectonic plates.
