- 1why is there a higher salinity near the equator?because of the heat. as the heat allows the water to vaporize, leaving behind the salt.
- 2why would there be a lower salinity near the continents than the middle of the ocean?as the water runs into the ocean water from lakes and rivers, it dilutes the water it comes in contact with. then the water water salinity decreases
- 3why would there be a higher salinity near the north and south pole?as the water freezes, the water turns into a solid(ice), the salt is left behind. Leaving the remaining water to become saltier
- 4what is density?the measure of the amount of mass a given volume holds
- 5where does salt come from?1. Land, as the water seeps through the land it picks up and collects the dissolved solids from millions of years ago
2. Volcanoes, they have high levels of molten rock and dissolved solids that go in to the ocean
- salt is made up of many chemicals, mostly of sodium (NA+) and chlorine (Cl-) - 6examples of density1. a bowling ball has a higher density than a volleyball of the same size
2. a sponge has a lower density than a rock of the same size - 7what is another difference between freshwater and salt water?FREEZING POINT
- 8why is salt water more dense than fresh water?when salt is dissolved in water, it is more dense because the dissolved salt adds mass to the water, objects tend to float better on dense surfaces therefore salt water you can float better on salt water
- 9how is the freezing point a difference of salt water and fresh water?1. the more dense a material is, the lower the freezing point is
- the dissolved salt tin the water makes the water more dense but lowers the freezing point
2. freshwater has a freezing point of 0 degrees Celsius, salt water has a freezing point of -1.9 degrees - 10If you wanted to show this salinity how many grams of salt would you put into 1 L of water?0.5 grams
- 11Of this 70% of water....97.2% is salt water
2.8% is freshwater - 12salinity is ....the amount of dissolved salt there is in a body of water
