🗑
|
||||
| Coriolis effect | The apparent curving of the path of a moving object from an otherwise straight path due to the Earth's rotation.
🗑
|

| Currents in general are influenced by these three things: | Weather, Earth's Rotation, and Position of Continents.
🗑
|
||||
| One of the longest surface currents. It is a warm current carrying warm waters from the Caribbean to the British Isles. | The Gulf Stream.
🗑
|

| Surface Currents are controlled or caused by three things: | Global Winds, the Coriolis Effect, and Continental Deflections.
🗑
|
||||

🗑
|
||||
| Global Winds near the poles blow in what direction? | West to East.
🗑
|

| The Coriolis Effect causes surface currents in the Northern Hemisphere to turn ___________________. | Clockwise.
🗑
|
||||
| The Coriolis Effect causes surface currents in the Southern Hemisphere to turn___________________. | Counterclockwise.
🗑
|
||||
| When surface currents meet continents, the currents bounce off the land and change direction. | Continental Deflection.
🗑
|
||||
| Warm water currents start near the ______________ and carry __________________ water to other parts of the ocean | Equator, warm.
🗑

||||
| Density | The amount of water in a given space, or volume.
🗑

||||
| Deep currents form in the ocean where there is increased ____________________. | Density.
🗑

||||
| Density is influenced by two factors: | Salinity and Temperature.
🗑
|
||||
| Salinity | A measure of the amount of dissolved salts or solids in a liquid.
🗑
|
||||
| How to Deep Currents Form? | Decreasing Temperature of Water, Increasing Salinity through Freezing and Increasing Salinity through Evaporation.
🗑
|
||||
| Less dense water currents will always flow on __________ of more dense water currents. In other words, the densest current will always be closest to the bottom. | Top
🗑
