ocean currents
| Question | Answer |
|---|---|
| What is the relationship between temperature and density | Colder water is denser and warmer water is less dense |
| What are 3 factors that affect surface currents | They are global winds coriolis effect and continental deflection |
| What happens to ocean currents whenthey approach a body of land | When ocean currents get close to land they change direction |
| What causes convection curents to form | Convection currents are caused by differences in water density |
| What causes upwellings | Wind cause upwellings |
| What is the relationship between ocean winds and currents | Ocean winds determine which way the surface currents go |
| What causes an increase of water density and results in deep ocean currents | Warm water loses energy to its surroundings and cools down turning into the deep ocean currents |
| What has the greatest effect on the growth of ocean life | The factor that has the greatest effect on the growth of ocean life is ae upwellings because they provide food fromthe deeper waters to the organisms that live near the surface. |
| How does heat energy move in the the global ocean | Heat energy in warm surface currents is transferred to thenearth's poles by wind |
| What are 3 steps that show the energy transfer that create ocean currents | First there are solar energy from the sun, this causes wind energy which causes surface currents. |
| What type of current happens when the surface water becomes more dense and sinks | The type of current that occurs is deep currents |
| What is an upwelling and why is it importnt to ocean life at least 3 reasons | Upwellings are important to ocean life because they transfer matter such as food from the dee ocean to the surface where is helps feed the organisms that live there Without upwellings the organisms that rely on the food from the deep oceans would die |
| If a region of the ocean has a large amount of salt water how would the movement of water change | The salinty in that region would increase and since there is more salinty the water in thatarea would be more densesince the water is more dense it will sink from the surface and create a deep ocen current |
| Describe how ocean waves and currents form and how they transfer energy around the world | Ocen waves and currents are cause by winds which is powered by the solar energy they tranfer matter and enegy by moving from warer regions of the ocean to colder aresin the process they transfer solar energy |
