Ocean Study Stack
Nicholas Frissora's ocean study stacks
| Question | Answer |
|---|---|
| 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. |
