|---|---|---|---|---|---|
| what is the relationship between density and water temperature | water that is colder is more dense than water is warmer
🗑
|
||||
| what 3 factors affect currents? | 3 factors are global winds, continental deflection, and the corolis effect
🗑
|
||||
| what happens to ocean currents as they approach a body of land? | They deflect off of the continent and keeps on going.
🗑
|
||||
| What causes convection currents to form? | When surface currents and deep currents link together in the ocean.
🗑
|
||||
| What causes upwellings? | Winds cause upwellings in the ocean.
🗑
|
||||
| What is the relationship between ocean and wind currents? | Ocean winds determine which direction the ocean currents will flow.
🗑
|
||||
| What does heat do in the formation of convection currents? | When water loses heat or cools it sinks to the bottom of the ocean.
🗑
|
||||
| What causes an increase in density and results in deep ocean currents? | Warm water loses its energy to its surroundings and cools down turning into deep ocean currents.
🗑
|
||||
| What has the greatest effect on growth of ocean life? | An upwelling because its brings them nutrient rich water from the deep ocean water and food to surface animals.
🗑
|
||||
| How does heat energy move in the global ocean? | The ocean currents move the heat energy which are transferred to Earth's poles by wind.
🗑
|
||||
| What are 3 steps that show the energy transfer that creates ocean currents? | Solar energy, wind energy and ocean energy
🗑
|
||||
| What type of current happens when the surface water becomes more dense and sinks? | It is a convection current because water from a surface current may become a deep current in the areas where water density increases.
🗑
|
||||
| What is an upwelling and why is it important to ocean life? | An upwelling brings nutrients, nitrates, and iron up to the surface animals that cannot travel far down into the ocean for food.
🗑
|
||||
| If a region of the ocean has a large amount of salt water, how would the movement of water be affected in that area. | The salinity (or amount of salt in the water) in that region would increase and since there is more salinity the water in that area would be more dense, it will sink from the surface and create a deep ocean current.
🗑
|
||||
| Describe how ocean waves and currents transfer solar energy around the globe. | Ocean waves and currents are caused by wind which is powered by solar energy. Ocean waves and currents transfer matter and energy by moving from warmer regions of the ocean to colder regions and in this process they transfer the sun's solar energy around
