I want to know the answer to the following question:
What natural process formed the land masses that would become the Samoan islands?
All the background I'm provided with is that "The Saleaula lava fields situated on the central north coast of Savai'i are the result of the Mt Matavanu eruptions which left 50 km² (20 sq mi) of solidified lava.". Is that enough to answer the question?
Answer: no
