Answers

1. Plate tectonics is the scientific theory that describes the movement and interaction of the Earth’s lithospheric plates.
2. The main types of plate boundaries are divergent, convergent, and transform boundaries.
3. Tectonic plates move due to the forces generated by mantle convection, slab pull, and ridge push.
4. The theory of continental drift, proposed by Alfred Wegener, suggests that continents have moved over geological time to their current positions.
5. A subduction zone is a region where one tectonic plate is forced beneath another, leading to volcanic activity and earthquakes.
6. Mountains are formed through plate tectonics when two continental plates collide, causing the crust to buckle and fold.
7. The Ring of Fire is a region around the Pacific Ocean where many volcanic eruptions and earthquakes occur due to plate tectonics.
8. Earthquakes are related to plate tectonics as they occur when stress builds up along plate boundaries and is released as seismic energy.
9. A mid-ocean ridge is an underwater mountain range formed by divergent plate boundaries where new oceanic crust is created.
10. Volcanoes are related to plate tectonics as they often form at convergent and divergent plate boundaries where magma reaches the surface.
11. Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.
12. Plate tectonics affect the Earth’s surface by creating mountains, ocean basins, earthquakes, and volcanic activity.
13. A transform boundary is a plate boundary where two plates slide past each other horizontally.
14. Plate tectonics contribute to the rock cycle by recycling crustal material through processes like subduction and volcanic activity.
15. Evidence supporting the theory of plate tectonics includes the fit of continental coastlines, fossil distribution, and the alignment of geological features.
16. Plate tectonics influence climate by affecting the distribution of continents and ocean currents, impacting weather patterns.
17. A tectonic plate is a large, rigid slab of the Earth’s lithosphere that moves and interacts with other plates.
18. Plate tectonics create ocean basins through seafloor spreading at divergent boundaries.
19. Mantle convection drives plate tectonics by causing the movement of molten rock in the Earth’s mantle, which in turn moves the plates.
20. Plate tectonics affect the distribution of natural resources by creating and concentrating minerals, oil, and gas deposits through geological processes.
