How did Japan's archipelago form?

Explanation:

Most archipelagoes are made of oceanic islands. This means the islands were formed by volcanoes erupting from the ocean floor. ... The Japanese archipelago consists of four large islands, from Hokkaido, in the far north, through Honshu, Shikoku, and Kyushu in the far south.

Volcanoes.

Explanation:

There are many theories about this, though Japan was not discovered until the Chinese stumbled upon it, trying to find a potion of immortality(yes, I know, it sounds silly) and BOOM, Japan was Japan. I personally suspect volcanoes since for volcanoes to go extinct, they must have spewed a LOT of lava. Take mount Fuji, an dead volcano. it probably accounted for making about 13% of Japan's landmass. Also, since water goes down during the winter, Japan might have even existed back in the Ice Age.

the aksumite empire was an ancient kingdom located in what is now northern ethiopia from the period of 100 ad to 940 ad. its capital was the city of aksum. the kingdom established itself as one of the 4 great powers at its time, along with persia, rome, and china.

the kingdom was rich in goods like gold, iron, and salt. it established strong commercial ties with the regions governed by rome, egypt, and persia (arabia). aksum was a key location in this commercial network. trade was also facilitated with the introduction of the aksumite currency.
