| Question | Answer |
|---|---|
| ocean water has a higher concentration of ___________ __________ than freshwater | sodium chloride(salt) |
| when water vapor rises the vapor cools and starts to form clouds this is called | condensation |
| types of water on earth from greatest to least | saltwater, ice/glaciers, groundwater |
| gases most abundant in the ocean | oxygen and carbon dioxide |
| amount of water on earth remains fairly constant because | water that evaporates comes back as precipitation |
| way to conserve water | water your lawn in the morning or evening |
| deep ocean currents are caused by | differences in density |
| waves are caused by | wind |
| condensation occurs because | the temperature decreases |
| evaporation occurs because | the temperature increases |
| what does ocean water have that fresh water does not? | higher concentration of sodium chloride |
| lowest point of a wave | trough |
| highest point of a wave | crest |
| what changes as you go deeper in the ocean | pressure increases(more) & temperature decreases(colder) |
| why does the ocean have so many dissolved elements? | weathering and erosion of rocks |
| why do we have high tides and low tides? | the moon's gravity pulls the ocean causing it to rise and fall |
| about how much time is it from high tide to low tide? | 6 hours |
| the highest point of a wave to the lowest point of a wave | waveheight |
| if high tide is at 3:00 pm low tide will be | about 9:00 pm |
| if low tide occurs at 2:00 am high tide will be | about 8 am |
| effect of Earth's rotation on direction of the wind and currents | Coriolis effect |
| what is an area of low salinity in the ocean? | mouth of a river |
