Science
| Term | Definition |
|---|---|
| What is the composure of earth ocean and where are they located? | |
| How does temperature in salinity affect density? | When salinity increases density decreases |
| What can sea floor features? Tell us about our planet | C4 features give us clues is to how our planet formed and continues to change overtime |
| How many oceans are there | 1 |
| How many basins are there | 5 |
| What are the basins | Atlantic, Southern,Arctic, Pacific, and Indian |
| What is composition | Make up, Structure, Parts, Pieces, and ingredients |
| Salinity(salt in the ocean) | 3.5% |
| Ocean water is salty because of | Acid rain, runoff from rivers and streams, and Hydrothemal vents |
| Temperature | The degree of hotness or coldness of an object |
| Salinity | The dissolve salt content of a body of water |
| Density | The amount of mass in a given space (volume) |
| Does a baseball have more or less than than a tennis ball? | More |
| More dense liquids will | Sink |
| Less dense liquid will | Rise |
| Temperature increases density | Decreases |
| As temperature decreases density | Increases |
| As salinity increase density | Decreases |
| Which diagram has the highest salinity | Ocean, death of salinity also increases temperature decreases because cold water is more dense in sinks |
| Temperature | Decreases |
| Salinity | Increases |
| Density | Increases |
| Humans have explore less than____ of the ocean floor | 10% |
| Sonar stands for | Sound navigation in ranging |
| Sonar uses____ Waves to measure depth | Sound |
| Bathymetric maps show | The depths of the ocean all over the globe |
| These are made using Sonar and | Satellite altimetey |
| Continental shelf extend form | The edge of the continental slope |
| Confidential shelf Formed by | Deposition |
| Continental slope located | After the shelf |
| Continental slope formed by | Erosion |
| Abyssal plains description description | A smooth flat area |
| Abyssal plains similar to | Planes on land |
| Abyssal plains formed by | Weathering |
| Seamount | Sea mountains rising from the ocean floor |
| Seamount formed by | Covering plates |
| Guyot | Volcanic mountain with a flat top found underwater |
| How does seamount become guyot | Guyot are sea mounts in which erosion by waves destroyed top believing in a flat top |
| A seamount that reaches the surface becomes a | Volcanic islands example Hawaii formed by converging plates |
| Trenches are located in the______ part of the ocean | Deepest |
| Trenches are formed by | Tectonic plates coming together |
| The deepest point of earth is called | Challenger deep it is located in the deepest part of the ocean |
| Mid ocean rages formed by | Diverging plates |
