Primary Production: the synthesis of organic chemicals from carbon dioxide (mostly happens through photosynthesis)
Upwelling: the motion of cooler, usually nutrient-rich, water towards the ocean surface

Why Earth Has Two Levels | Hypsometric Curve
To learn more about this topic, start your googling with these keywords:
Hypsometric Curve: Basically, a chart that shows the proportions of surface area at every elevation on a planet.
Crust: Earth's outermost layer, made out of two distinct materials – oceanic crust (which is denser) and continental crust (which is less dense).
Lithosphere: The rigid outer layer of Earth, including the crust and the hard, un-bending part of the upper mantle.
Subduction: The process of an ocean plate crashing into another plate and getting forced to dive down into Earth's mantle.
Isostasy: Describes the way earth's crust sort of floats in the underlying mantle. Continental crust is less dense and thicker, and floats higher than the oceanic crust, which is denser and thinner. Geologists talk about things like "isostatic rebound," which is what happens after an ice age, when the ice melts off a continent and the continent lifts up, like a floating raft in a pool after someone gets off (though continents rise more slowly).

From the creators of the popular science show with millions of YouTube subscribers comes the MinuteEarth podcast. Every episode of the show dives deep into a science question you might not even know you had - but once you hear the answer, you’ll want to share it with everyone you know. Our team of scientists digs into the research and breaks it down into a short, entertaining explanation jam-packed with science facts and terrible puns. We’ll tell the incredible story of how monkeys crossed the Atlantic ocean on natural rafts, and we’ll explain why it gets hotter the deeper you dig underground.
