Answer:
1. c. Island arc chain.
2. d. Indian and Eurasian
3. a. divergent
4. c. mid ocean ridge
Step-by-step explanation:
The convergence of oceanic and oceanic crust can leads in the formation of volcanoes that may rise above sea level forming Island. The formation of Mount Everest occurs from the fusion of tectonic between the Indian and Eurasian tectonic plates about more than ten millions of years ago. Seafloor spreading occurs at divergent plate boundaries in which less-dense material rises from the earth crust forming a mountain or elevated area of the seafloor. The geologic feature formed at divergent boundary is mid ocean ridge.
