- Currents are caused by wind, gravity and density.This is imoprtant because by these moves , water of the whole world can travel and moderate the weather.
- Eddy currents are tiny and rotates in .
- The upper layers of the sea are called Surface Circulation.
- Deep Circulation is caused by density.
- Gyre are the currents that goes in circles, besides there are 5 big ones in whole world.
- One is located at the Indian Ocean , this is made up of wind and gravity by the coriolis effect and sea topography.
- When water is cold its molecules are more close together, however when water is frozen its molecules spread out from each one.
- Thermal expantion causes the sea to expand.
- Earth rotates faster in the equator than in the poles.
- El nino was caused by a giant current.
- Temporary currents just happened in some seasons.
- Rip currents are strong channels of water flowing seaward from near the shore.
- We call longshore currents when a wave reaches a beach or coastline, it releases a burts of energy that generates a current, which runs parallel to the shoreline.
- Upwelling currents involved wind-driven motion of dense, cooler , and usually nutrient-rich water towards the ocean surface, replacing the warmer , usually nutrient-deplented surface water.
- El nino is one of the most misterious phenomenos that even the scientis can't figure out the reason that provocates them.
- El nino causes lots of different kinds of damages.Every year there is a different el nino.
Here it shows different types of temperature in places around the map and also different times
