2. describe what role did the analysis of mid-ocean ridges play in the
historical development of plate tectonic theory?

Plate tectonics theory scientifically explained the movement of continents, formation of islands, earthquakes and volcanoes.

Explanation:

Continental drift theory is a pioneer in the field of geology which is proposed by Alfred Wegner but it failed to explain the movements of continents, island formation, etc. Plate tectonic theory proposed the plate concepts which is completely new to geomorphology. It also explained about the movement of plates. Mid oceanic ridge is an area of the divergent or constructive plate boundary which looks like the shape of 'S' between the North American and the Eurasian plate in the North Atlantic ocean and then between the South American and the African plate in the South Atlantic ocean.
