| Question | Answer |
|---|---|
| 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 |
| The oceans were filled during tens of thousands of years with water form ________ and possibly ice from comets and asteroids. | Precipitation |
| In areas where tectonic plates collide, the seafloor has deep _______. | Trenches |
| In areas where tectonic plates separate, the seafloor has mid-ocean _____. | Ridges |
| Oceanographers use _____________ to explore the seafloor. | Submersibles |
| The continental shelf, continental slope, and continental rise are regions of the continental _______. | Plains |
| What is the term for an uncrewed submersible used to explore the seafloor? | ROV |
| Which zone does not receive any sunlight? | Deep Zone |
| What happens to density as depth increases in oceans? | It increases. |
| List 2 main categories of resources on or beneath the ocean floor. | Energy resources & minerals |
| How does light that is absorbed affect the temperature of the water? | The more light absorbed, the warmer the water will be. |
| Why do organisms that perform photosynthesis live only in the surface zone? | The Surface Zone receives the greatest amount of sunlight. |
| Most bioluminescent deep-sea organisms emit blue and green light. What is the advantage of emitting these colors instead of other colors? | Blue & green penetrate deeper into the sea. |
| Why does the salinity of surface water in polar regions differ from the salinity of surface water in temperate of tropical regions? | Warm water evaporates more rapidly than cold water. When water evaporates, salt is left behind. |
| A feature on the ocean floor. | Abyssal Plain |
| Water in the oceans. | Seawater |
| Refers to dissolved salt content. | Salinity |
| Slightly salty. | Brackish water |
| The large, flat areas of the seafloor that extend across the deepest parts of the ocean floor are the _________. | Abyssal Plains |
| Physical characters that are used to classify the ocean into zones include water depth, temperature, salinity, density, and amount of ________ received. | Sunlight |
| Water from a sea or an ocean that has a average salinity of 35 ppt is _____. | Seawater |
| Two main resources on the seafloor are ________ and _______ resources. | Minerals; energy |
| The measure of the mass of dissolved solids in a mass of water is called _______. | Salinity |
| Freshwater mixed with seawater is ___________. | Brackish Water |
| True/False--Fix if False: The five oceans are the Antarctic Ocean, the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Southern Ocean. | False; Change Antarctic to Arctic. |
| True/False--Fix if False: Salinity is a measure if the mass of dissolved solids in a mass of water. | True |
| A salinity of 35 parts per thousand means that if you measured 1,000 g of seawater, 965 g would be water molecules and 35 g would be salts. | True |
