You have learned from your previous lessons that lithospheric plates or the solid part of the Earth are gradually moving to form different geologic events such as earthquakes, mountain buildings, and volcanoes. But what causes these plates to move? What is the evidence that the Earth’s Plates are moving? These questions ignited our scientists’ curiosity to look for answers and lead to the development of the following ideas: Continental Drift Theory, Seafloor Spreading, and Earth’s Magnetic Reversal.
After going through this module, you are expected to enumerate the lines of evidence that support the plate movement (S9ES –Ia-j-36.6).
Specifically, you will learn to:
✓ investigate the pieces of evidence of the Continental Drift Theory;
✓ demonstrate the evolution of the oceanic crust through Sea Floor Spreading; and
✓ realize the importance of the seafloor spreading process relative to the Continental Drift Theory.Science10_q1_mod5_evidence-of-plate-movements_ver2
