| Question | Answer |
|---|---|
| A feature on the ocean floor | abyssal plain |
| Water in the oceans | seawater |
| Refers to dissolved salt content | salinity |
| chemical process in which light energy, water, and carbon dioxide are converted into sugar | photosynthesis |
| To operate with hands or by mechanical means in a skillful manner | manipulate |
| slightly salty | brackish |
| What is the term for an uncrewed submersible used to explore the seafloor | ROV |
| Which zone does not receive any sunlight | deep zone |
| How does light that is absorbed affect the temperature of the water | temperature increases |
| Why do organisms that perform photosynthesis live only in the surface zone | that's the zone that receives the most sunlight and photosynthesis is driven by sunlight |
| In areas where tectonic plates collide, the seafloor has deep | trenches |
| In areas where tectonic plates separate, the seafloor has mid-ocean | ridges |
| Two main types of resources are | mineral and energy |
| What do oceanographers use to explore the seafloor | submersibles |
| What happens to density as depth increases in oceans | decreases |
| How have tectonic plates affected oceans | when they collide and separate, they create ocean ridges |
| How have comets and asteroids could have been a second source of water for Earth's oceans | ice from these objects added to the water filling Earth barins |
| How does an ocean trench form | tectonic plates |
| How does a mid-ocean ridge form | tectonic plates |
| Why does the salinity of surface water in polar regions differ from the salinity of surface water in temperature or tropical regions | the temperature difference |
