12 Questions
Match the components that power the global ocean current system:
Salt = Some sunlight
Match the time period when the German Naval Observatory conducted the ocean-tracking experiment:
1864-1932 = 1800s
Match the entity that released the message in a bottle in the Indian Ocean:
German Naval Observatory = Shipwrecked sailor
Match the reason why the message in a bottle was released:
To figure out ocean currents = To send a love letter
Match the year when the message in a bottle was found in Australia:
2018 = 1864
Match the impact of climate change on the global ocean current system:
It might break the system = It would strengthen the system
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
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
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
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
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
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
Learn about the powerful system that keeps Earth's oceans healthy and thriving. From shaping ecosystems to influencing human civilization, discover the significance of ocean currents and what drives this global phenomenon.
