Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How heavy is the Open ocean convection?North Atlantic Deep Water (NADW) and Antarctic Bottom Water (AABW)
2. What is the location?High-latitude open ocean regions, notably the North Atlantic and Southern Ocean
3. What is the process?Formation of dense surface water that sinks, driving deep ocean circulation
4. Why does surface water become denser?Surface water becomes denser when it cools or when evaporation and sea ice make it saltier, so it weighs more than the water below.
5. How does open ocean convection help the climate?It creates deep water that drives the ocean’s great conveyor belt, moving heat, oxygen, and nutrients around the world.

Mesoscale Oceanographic Process: Oceanic phenomena occurring at horizontal scales of tens to hundreds of kilometers.
Atmospheric Forcing: The influence of the atmosphere on ocean processes, such as wind stress and heat exchange.
Freshwater Flux: The rate at which freshwater is added to or removed from the ocean, affecting salinity.
