Ocean Study Stack

Nicholas Frissora's ocean study stacks

Name the five oceans. Atlantic, Pacific, Indian, Southern, Arctic
What are two sources of water in Earth's oceans? Condensation and asteroids/comets.
Define Salinity. A measure of the mass of dissolved solids in a mass of water.
What is polarity? It is when an item has a slightly negativly charged side and a slightly positivly charged side.
What is cohesion? The attraction among molecules that are alike.
What is adhesion? The attraction of molecules that are not alike.
True or False. The density of ice is lower than the density of the same volume of liquid water. True.
True or False. The density of freshwater is lowest at 4 degrees celcius. False it is greatest.
In which states of matter can watter exsist in nature on Earth? The three states Solid,Liquid,Gas.
What would happen if you placed drops of water on a counter? It would form little droplets of water.
What causes the drops to form? Cohesion comes into play combining like molecules to stick to each other.What
What happens when you add sugar to water? The sugar will dissolve.
What causes waters unique properties? Polarity is what makes it unique as it can help mix the water with other things and dissolve other things.
Why does ice float in water? The ice is less dense than the water therefore it floats in the water.
Why does ice make it possiple for organisms to live in the lake in the winter? The warm water is pushed down to the bottom where all the fish can live.
Why do water molecules attract to each other? This happens as the hydrogen and oxygen molecules of the water connecting to each other through polarity.
Define what an ocean current is. A large volume of water flowing in a certain direction.
Define gyre. A circular system of currents.
Name 5 major gyres. North Pacific, South Pacific, North Atlantic, South Atlantic, Indian Ocean.
Explain why upwelling occurs. When wind blows across the oceans surface and pushes water away from the surface.
Name one benefit of upwelling. It brings nutrient-rich water to the surface.
Describe Density Currents. They are currents that move downward and they carry water from surface to deeper parts of the ocean. And are not caused by wind.
What are Density Currents caused by? They are caused by the changes in density moving from high density to low density.
What current moves water horizontally? The surface currents.
