| Question | Answer |
|---|---|
| How do you determine the ocean floor distance when sound travels at a certain time? | You take the time and divided by 2. Then you use that time to multiple by 1,531 miles. |
| What kinds of chemcial and minerals that are two expensive to get why? | Gold and manganese. They can't be claim because it's too expensive and it could ruin the enviorment. |
| Why are bathpheres better then bathscraphs and human divers. | They are better because bathscraphs are free moving unlike bathspheres. They can last longer in water a human diver. |
| Contiental Shelf | gently extends downward from the contients of the ocean |
| Contiental Edge | point of which the shelf surrounding each con. begins to angle down the sharply to the ocean depths |
| Contiental Slope | the clifflike dropp beyond the con. shelf and the true boundary between the con. and the ocean floor |
| Contiental Rise | strethes from the lower part of the slope to the deepest part of the ocean |
| Abyssal Plain | leads to the ocean bottom formed and by under sea rivers, currents and cooling part of the Earth crust |
| Mid-Ocean Ridge | the longest mountain range in the world |
| Seamounts | free-standing mountains formed by volcanoes munerous in the Pacific |
| guyot | a flat-topped seamount |
| islands | formed by the top of seamounts |
| What creates the natural features | natural forces such as volcanoes and hurricanes ect. |
| What are the three kinds of sediments and examples of each one? | Organic-protists and marine animals (contains carbon). Inorganic-soil, iron and glaciers(does not contain carbon). Chemical and minerals- gold and manganses |

| What is the difference between sonar and radar? | Sonar goes through water and radar goes through air. |
| How much does sound travel at? | 1,531 miles per second |
| Why do people use sonar? | To map the ocean floor. To detect ships, submarines and shipwrecks. It helpful in war. |
| A meter was in a layer for possibly how long and what may it caused? | 65 million years and it could have caused the dinsours to extinct. |
