Understanding Plate Margins
Plate tectonics explains the movement of the Earth's lithosphere, which is broken into tectonic plates. These plates interact at various margins, leading to different geological phenomena.
Statement 1: New oceanic crust formation
- At **convergent plate margins**, one plate is forced beneath another in a process called subduction.
- This results in the recycling of oceanic crust back into the mantle, not the formation of new crust.
- Therefore, **Statement 1 is incorrect**.
Statement 2: Crust creation and destruction
- At **divergent plate margins**, tectonic plates move apart, allowing magma to rise from the mantle, creating new oceanic crust.
- Conversely, at convergent margins, crust is destroyed as it subducts.
- Thus, while crust is created at divergent margins, it is destroyed at convergent ones. This means that **Statement 2 is also incorrect**.
Conclusion
- Both statements misrepresent the dynamics of plate margins.
- Hence, the correct answer is **option 'D'**: Neither Statement 1 nor Statement 2 is correct.
Understanding these fundamental processes is crucial for grasping the complexities of geological activity and its implications for Earth’s landscape and seismic activity.
