Question

the passage describes the movement of tectonic plates as a dynamic and ongoing process. based on this description, which of the following inferences can be made about the earths surface in the distant future? answer: a. mountain ranges will erode and disappear entirely. b. the earths surface will eventually become static and unchanging. c. volcanic and earthquake activity will cease completely. d. the earths surface will continue to change and evolve due to plate tectonics. question: the passage mentions the discovery of seafloor spreading in the 1960s as a key factor in the acceptance of plate tectonics theory. how did this discovery change the understanding of continental movement? answer explain:

Explanation:

The passage describes plate tectonics as a dynamic and ongoing process. This implies continuous change to the Earth's surface due to plate - related activities. Options A, B, and C suggest static or ending processes which go against the dynamic nature described.

The discovery of seafloor spreading showed that new oceanic crust was being formed continuously at mid - ocean ridges. This indicated that continents were not fixed but were moving as part of the tectonic plates. It provided evidence for the idea of continental drift and a mechanism for how continents could move over time.

Answer:

D. The Earth's surface will continue to change and evolve due to plate tectonics.
