This primary force drives surface currents by transferring energy to the water.
What is wind?
These microscopic organisms are the primary producers at the base of most marine food chains.
What are phytoplankton?
Covering 30% of the Earth's surface, this is the largest and deepest ocean on Earth.
What is the Pacific Ocean?
This type of cloud is associated with thunderstorms.

What is mutualism?
A severe, blinding snowstorm makes visibility low, a condition often called this.
What is a whiteout?
This refers to the layering of ocean water due to differences in temperature and density.
What is strafification?
These currents, comprising 90% of the ocean, are driven by differences in density, temperature, and salinity.
What is thermohaline circulation?
This term refers to the increase in toxin concentration at higher levels of a food chain.
What is biomagnification?
This is the term for light produced by marine animals.
What is bioluminescence?
Meteorologists use this type of radar to detect rotation in thunderstorms.
What is Doppler radar?
This is the deepest part of the ocean, formed where crustal plates collide.
What is a Trench (or Hadal Zone)?
This phenomenon, in which warm water is pushed away from the equator, helps to maintain this crucial aspect of Earth's climate.
What is heat distribution?
These organisms, such as bacteria, break down dead material to recycle nutrients.
What are decomposers?
This is the name for a group of jellyfish floating together.
