Reveiw over Properties of water/Composition of ocean/OceanCurrents
| Question | Answer |
|---|---|
| What are the two sources for Earth's oceans? | 1)Salt Water & 2)Fresh Water |
| What is Salinity? | It is a measure of the mass of dissolved solids in a mass of water. |
| What is Seawater? | It's water from the sea or ocean that has an average salinity of 35 ppt. (Parts Per Thousand) |
| What is Brackish water? | Brackish water or brack water, is fresh water mixed with seawater |
| TROPICAL REGIONS Temperature: Salinity: Density: | Temp:As depth increases temperature decreases Salinity:As depth increase salinity decreases Density:As depth increase density increases |
| TEMPERATE REGIONS Temperature: Salinity: Density: | Temp:As depth increases temperature decreases Salinity:As depth increases density decreases Density:As depth increases density increases |
| POLAR REGIONS Temperature: Salinity: Density: | Temp:As depth increases temperature stays about the same Salinity:As depth increases salinity increases Density:Density remains fairly constant. |
| What is the largest ocean? | PACIFIC Ocean |
| What does a water molecule look like? | It has one big oxygen molecule and 2 smaller hydrogen molecules |
| List 3 ways water is a unique compound? | 1)Ice floats in water 2)Water exists in all 3 states 3)Water forms into drops when it spills |
| Chose correct answer The density of ice is lower or higher than the density of the same volume of liquid water. | Lower |
| Chose correct answer The density of freshwater is lowest or greatest at 4*C | Greatest |
| Chose correct answer The particles of liquid water are closer together or farther apart than the particles of the same volume of frozen water. | Closer together |
| What is adhesion? | The attraction between molecules that are different. |
| What is cohesion? | The attraction between molecules that are alike. |
| The ocean is mostly fresh water or salt water. | Salt water 97%of the ocean is salt water. |
| True/False The heat from the sun condenses the water in the ocean leaving only salt behind. | False Evaporates |
| Fill in the blank Ocean currents are caused by ____ and the amount of salt in the water. | Wind |
| Chose correct answer Very salty water is heavier or lighter than water that isn't salty | Heavier |
| What are Thermohaline currents? | They are warm salty ocean currents. |
| Has the amount of salt change in the ocean? | Nope |
| What is an ocean current? | It is a current that a river of water through the ocean. |
| Earth is the only planet with oceans that's why Earth has ______ ______. | Living things. |
| What would you say about water's polarity? | A condition in which opposite ends of a molecule have slightly opposite charges but the overall charge of the molecule is neutral. |
| Continued from last part of answer. | The negatively charged oxygen atom of one molecule attracts positively charged hydrogen atoms of other water molecule.This produces an attractive force between water molecules. |
