Ocean Surface Currents (Slides 1 & 2)
This surface current flows from Florida to Iceland and transports 25 times more water than all of the rivers in the world.
What is the Gulf Stream?
True or False: Finding Nemo got all of the details of the EAC correct.
What is false?
Suface currents warm or _____ some costal areas year-round.
What is cool?
True or false: Denser water moves along the ocean floor, while less-dense water flows above it.
What is true?
Waves in the ocean move in this pattern.
What is circular?
This effect causes surface currents to move in curved paths rather than straight lines.
What is the Coriolis effect?
EAC stands for this.
What is the Eastern Australian Current?
Surface currents greatly affect this in many parts of the world.
What is climate?
Surface currents carry warmer, less dense water from here to here.
What is the equator to the poles?
Ocean waves form because of this between the wind and the surface of the water.
What is friction?
Global winds blowing across the Earth’s surface create these.
What are surface currents?
The EAC flows this direction from the Great Barrier Reef.
What is southward?
Warm currents begin near here and carry warm water to other parts of the ocean.
What is the equator?
Deep water currents are mainly controlled by increases in this.
What is water density?
The _______ of a wave is its highest point, and the ______ is its lowest point.
What are crest, trough?
Because of the Coriolis effect, currents in the Northern Hemisphere turn _____________ while currents in the Southern Hemisphere turn __________.
What are clockwise, counterclockwise?
The EAC flows at speeds up to _____ miles per hour.
What is 4.5?
The Gulf Stream is this temperature of current.
What is warm?
Ocean water becomes denser when it gets _______ and ________.
What are saltier and colder?
A wave is defined as a transfer of this.
What is energy?
Surface currents are controlled by these four factors.
What are global winds, the Coriolis effect, continental deflections, and water temperature?
The EAC is located in this ocean.
What is the Pacific Ocean?
This happens when currents meet landforms and change direction.
What is conntinental deflection?
Starting at about this depth, water temperature becomes colder as depth increases.
What is 200 meters?
This type of wave requires some type of matter to travel through.
What are mechanical waves?
