| Question | Answer |
|---|---|
| what is polarity | condition in which opposite ends of a molecule have slightly different charges. |
| which states can water excist naturaly | solid liquid gas |
| what causes drops to form | cohesion (surface tension) |
| what causes waters unique properties | polarity |
| why does ice float in water | has a lesser density than water |
| what are the atoms of water | 2 hydrogen 1 oxygen |
| why is water sometimes called the universal solvent | it's the one thing everything needs |
| which substance has a stronger bond between its particles: water or alcohol. | alcohol |
| what are five of earths oceans | Pacific, Atlantic, Indian, Southern, Arctic |
| what are two sources of water for oceans | 1. condensation 2. asteroids and comets |
| what is salinity | a measure of mass of dissolved solids in a mass of water |
| 4 criteria scientists use to classify ocean zones | sunlight temperature salinity density |
| describe the surface zone | has the greatest amount of sunlight |
| describe the middle zone | wave lengths have been absorbed |
| describe the deep zone | plants cant grow here |
| why is river water near an ocean sometimes salty | the ocean water is either flowing into it or there are many rocks |
| define ocean currents | large volume of water flowing in a certain direction |
| what is a gyre | circular system of currents |
| what are the 5 main gyres | north pacific, south pacific, north Atlantic, south Atlantic, Indian ocean |
| what is a benifit of upwelling | it brings cold, nutrient-rich water from deep in the ocean |
| what is a density current | it carrys water from the surface to deep in the ocean |
| what are density currents caused by | changes in density |
| how do surface currents affect weather and climate | the warm water is being pushed in one direction and the cold water is being pushed in another |
| how do ocean currents affect weather and climate | the warm currents make the water warm on the surface |
