Seems right! Sorry for the pretty low quality question I didn't know what to ask haha.
Lol it's no problem at all
Give one plausible hypothesis for the formation of the Hawaiian Islands. Contrast with the formation of the Japanese Islands. What is the name for a group of islands?
The Hawaiian islands were formed by the island passing over a hotspot, while the Japanese islands were caused by the subduction of many plates. The islands are called island arc chains
Yep!
That is one plausible hypothesis for the Hawaiian islands forming (although the islands didn't pass over the hotspot because the islands didn't exist prior to their formation by the hotspot). Groups of islands are archipelagos. Island arc chains are specifically created by subduction.

The Hawaiian Islands were probably formed by volcanic activity. Magma rose to the seafloor, and piled up until an island formed. However, the crust was moving and the hot-spot that made the magma didn't, because it was under the crust. Therefore, more magma would be produced in a different crust-location and form into islands, forming the island chain. The Japanese Islands were formed by tectonic movement, especially subduction, and not magma coalescing. Both of these are groups of islands, also called 'Archipelagos'. oops, didn't see that this was answered while I was typing. . . Sorry!

ah archipelagos, i didn't think of that. @twoplustwoisten if you want to post the question in my stead feel free to

No thank you, words are hard. Besides, you answered first.
