Complete question is;
What features of ocean basins are chains of basaltic rock that stretch more than 1.5 times Earth's circumference around the world at spreading centers?
Answer:
Oceanic ridges

1) evaporation that involves moisture input into the atmosphere that is imperative for clouds to be formed that results in precipitation later .
2) condensation is the direct cause of precipitation and the most common circumstances behind the condensation is drop in temperature in the cloud system.
