Vocabulary
Wind movement as a result of Earth's rotation
Coriolis effect
True or false:
some ocean currents flow at or near the ocean's surface.
true
what are the three factors that influenced the surface currents in Earth's oceans.
1. global winds
2. locations of the continents
3. Earth's rotation - Coriolis effect
What temperature is on point A?
Around 28-30 degree celsius
Earth's surface currents flow in huge circular patterns
Gyres (JYRZ)
Winds and currents move in similar directions because currents are generated by ________
winds
Winds turn clockwise
Northern hemisphere
What temperature is on point B?
Around 8-10 degree celsius
streamline movement of ocean water in a regular pattern
ocean current
As wind blows, energy is transferred from the wind to the ocean. The energy transfer causes the water to move in a surface ocean ___________
current
Ms. A's question
South hemisphere
What temperature is on point C?
Around 0 to 2 degree celsius
horizontal movement of water in a regular pattern at the ocean's surface
surface current
If wind is moving from east to west and reaches the coast of a continent, which way will it deflect?
It will deflect the other way, which will then move towards the east
Can point C ever reach 26 to 30 degree celsius? Why?
No because the temperature is extremely cold. However, if global warming continues then there is a possibility that the temperature might pass 6 degree celsius.
change in direction of currents as they meet continents
deflection
Why does floating garbage tend to build up in certain places in the ocean?
Currents carry floating objects with them. When garbage reaches a gyres, it could be moved to the center as the surface current drift to the center of the gyre. Especially within north/south Atlantic Ocean, Pacific Ocean and Indian Ocean.
