Crust Formation Insights
Continental crust is primarily formed from lighter, silica-rich materials that rise to the surface through processes like subduction, where oceanic crust is pushed into the mantle. This melting and subsequent rise of magma contribute to the growth of continental crust over billions of years. In contrast, oceanic crust is continuously created and recycled through seafloor spreading, making it much younger than its continental counterpart.In this clip

Which statement BEST compares the rock found at an oceanic ridge to rock found at a deep ocean trench?
Which TWO things do the rocks provide evidence of in terms of the geologic understanding of Earth as discussed in the episode: episode\[Plate Tectonics Are What Makes Earth Inhabitable] and the clip: clip\[Volcanoes and Earthquakes]?
Rock at the oceanic ridge is younger because it forms when plates move in opposite directions.
