Question

1. which of these statements provides evidence that suggests that plate tectonics has been active on earth for billions of years? a the presence of deep - sea vents that support unique ecosystems b the discovery of fossilized plant and animal remains in sedimentary rocks c the observation of volcanic activity and earthquakes in certain regions of the world d the identification of magnetic stripes on the seafloor that correspond to changes in earths magnetic field over time

Explanation:

Fossilized plant/animal remains in sedimentary rocks can be dated to billions of years old, and their distribution across now-separated landmasses (due to plate movement) shows plate tectonics has operated for that timescale. Deep-sea vents relate to current tectonic activity but not long-term timeline; volcanic/earthquake observations show present activity; magnetic stripes confirm seafloor spreading but not billion-year scale activity.

Answer:

B. The discovery of fossilized plant and animal remains in sedimentary rocks
