Match the following terms with their descriptions:

Sverdrup = A unit of measurement for ocean currents, equivalent to one million cubic meters per second Co-motion = A phrase used to describe ocean currents, referencing 'currents' Density = A force driving ocean currents, due to differences in water temperature Atmosphere = The layer of gases surrounding the Earth's surface Signup and view all the answers

Match the following ocean characteristics with their descriptions:

2/3 = The portion of the Earth's surface covered by oceans Cold water = Denser than hot water, due to molecules being closer together 10 sverdrups = The current of all the Earth's rivers combined Blue planet = A nickname for Earth, due to its abundant oceans Signup and view all the answers

Match the following ocean current factors with their descriptions:

Wind = A factor controlling ocean currents near the surface Tides = A periodic rising and falling of the sea level, influencing ocean currents Earth's rotation = A factor affecting ocean currents, especially near the surface Land shape = A factor affecting ocean currents, especially near the coast Signup and view all the answers

Match the following ocean features with their descriptions:

Ocean conveyor = A huge ocean current that ties the oceans together Deep ocean circulation = A process driven by density, involving colder water sinking and warmer water rising Rivers = A source of freshwater, contributing to ocean currents Atmosphere = A layer of gases surrounding the Earth, much lighter than the oceans Signup and view all the answers

Match the following terms with their descriptions:

Hot water = More dense than cold water, due to closer molecules Cold water = Less dense than hot water, due to farther molecules Surface currents = Ocean currents controlled by wind, tides, and the Earth's rotation Deep ocean circulation = A process driven by density, involving colder water sinking and warmer water rising Signup and view all the answers

Match the following ocean characteristics with their descriptions:

1,000 years = The time it takes for a bit of water to make one loop around the ocean conveyor Hundreds of times = The weight of the oceans compared to the atmosphere 9/10 = The proportion of the ocean's water driven by density Ridiculous amounts = The quantity of water moved by the ocean conveyor Signup and view all the answers
