mechanism of plate movement quarter 1.pptx

Science 10

1. Plate movement, a fundamental geologic process, occurs due to the continuous motion of Earth's lithospheric plates, which float on the semi-fluid asthenosphere beneath them. This movement is the driving force behind the ever-changing face of our planet, responsible for the creation and evolution of continents, the formation of mountain ranges, and the occurrence of seismic activity along plate boundaries. Whether plates collide, pull apart, or slide past each other, their interactions shape Earth's surface, influencing geological features, climate patterns, and even the distribution of life on our dynamic planet.

7. DRIVING FORCES - either push tectonic plates toward each other or pull them apart. RESISTING FORCE- acts against the driving force

8. The main driving force behind plate movement is MANTLE CONVECTION

9. In Physics Convection is a HEAT TRANSFER. .   an energy transfer from an area of higher energy to one of lower energy.

10. Heat from the Earth's interior rises toward the mantle, increasing its kinetic energy and causing it to expand and spread out the plate.  

11. Kinetic is a type of energy which means energy in motion, and the other type is potential which means energy at rest

12. The upward force of mantle convection causes the newly created crust to push the adjacent plates away In English when we say adjacent, it means being in close proximity . In Geometry-angles having a common side and a common vertex.  

13. Ridge Push-the denser plate sinks/subducts into the mantle, it pulls the rest of the plate along with it. GRAVITY -Force that attract the body toward the center of the Earth.

14. - subducting slab sinks into the hot mantle because of temperature. The rest of plate to which the slab is attached to is being pulled as well.

15. SLAB SUCTION - occurs between two colliding plates, one of which is subducting underneath the other.

16. SLAB RESISTANCE-when plates collide at a plate boundary in subduction zone, the force will resist movement .

17. In 2 minutes construct one or two sentences in any sheet of paper about why do we need to study plate movement? After two minutes I will be choosing lucky two learners to share their insight or thoughts.

18. It helps us understand the dynamic nature of our planet and the processes that have formed and continue to modify its features.

19. By studying plate movement, scientists can identify areas where tectonic plates interact and are more likely to generate seismic activity. This information is vital for earthquake prediction and mitigation efforts, which can save lives and reduce property damage.

20. Understanding plate movement helps predict and manage volcanic eruptions .

21. Studying plate movement helps in understanding patterns of biodiversity and evolution

22. Many valuable natural resources, such as minerals, oil, and natural gas, are found in regions associated with plate boundaries and their movements. Studying plate tectonics helps locate and access these resources.

23. Many valuable natural resources, such as minerals, oil, and natural gas, are found in regions associated with plate boundaries and their movements. Studying plate tectonics helps locate and access these resources.

24. 1 . Subduction zones generate a gravitational force known as “ _______ pull," which contributes significantly to the movement of tectonic plates . 2. At mid-ocean ridges, the upward force of mantle convection causes the phenomenon known as "_______ push.” 3. Mantle convection is primarily driven by heat from the Earth's interior, causing material in the semi-fluid _______ to rise and create convection currents. SLAB RIDGE ASTHENOSPHERE

25. 4. The heat-driven rising and sinking of material in the asthenosphere create convection currents that set the lithospheric plates in _______. 5. Ridge push is the force that pushes plates away from mid-ocean ridges as newly formed oceanic crust exerts an upward _______. MOTION FORCE
