Oceanography
| Question | Answer |
|---|---|
| What is Matter? | Anything that takes up space and can be weighed. |
| What is Volume? | The amount of space an object occupies. |
| What is Density? | The amount of matter in a given shape. |
| What is the formula for Density? | D=m/v |
| What is the most abundant salt in the ocean? | Sodium Chloride |
| What is Salinity? | The total amount of dissolved solids in water. |
| If Salinity increases when is removed, what are some ways Salinity is increased? | Salinity increases when water freezes or evaporates. |
| If Salinity decreases when is added, what are some ways Salinity is decreased? | Salinity decreases by precipitation, runoff, and melting of glaciers |
| What is Thermocline? | A layer of water when temperature is decreasing rapidly. |
| What is Pycnocline? | A layer of water where there is a rapid increase in density with depth. |
| What are Plankton? | Organisms that float. |
| What are Nekton? | Organisms that swim. |
| What are Benthos? | Organisms living on the seafloor. |
| What is Upwelling? | The rising of cold water from deep layers to replace warmer surface water that is blown out to sea. |
| What resources does Upwelling provide? | Upwelling provides nutrients to the surface which promotes the growth of microscopic plankton. |
| What is the largest and deepest ocean? | Pacific ocean |
| What is the Smallest ocean? | Arctic |
| What is wave height? | Vertical distance between trough and crest |
| What is wave length? | Horizontal distance between 2 successive troughs or 2 successive crests |
| What are 3 things that can help you determine the size of a wave? | Wave height, wave length, and "the fetch" |
| What does fetch mean? | The length of the wave depend on wind blows, the length of time the wind blows across the water, and the distance the wind blows. |
| What is a seamount? | A volcanic peak on the ocean floor that does not reach the surface. |
| What is the continental slope? | A part of the ocean next to the continental shelf where the seafloor drops off at a steep slope. |
| What is the continental shelf? | A part of the ocean next to the continental shelf where the seafloor drops off at a steep slope. |
| What is the continental rise? | A gradual incline between ocean basin and continental slope. |
| What are the abyssal plains? | Deep in ocean and has extremely flat features. |
| Where are the mid-ocean ridges? | A chain of underwater mountains. |
| What resources do we get from the ocean? | Salt, sand, oil, gas, and gravel |
| What color travels the deepest in the ocean? | Blue |
| What percentage of living space do oceans make up? | 99% |
| How much does the Pacific ocean cover on earth? | 1/3 |
| The energy that drives surface ocean currents comes from ____. | |
| Density currents move ____. | |
| What are the 2 types of ocean currents? | |
| In addition to salinity, what factor affects the density of seawater? | |
| What is true about an ocean current that is moving toward the equator? | |
| Ocean currents that move toward the poles are ____. | |
| The horizontal distance between two successive crests is called the ____. | |
| Seafloor spreading occurs where 2 tectonic plates are ______________________. |
