Ocean Surface Currents
What are sream like movements of water that occur at or near the surface of the ocean?
Surface Currents
Who was a disney character that fallowed the The East Australian Current
NEMO!
what happens when a current meets a landform?
They change direction.
What are deep currents?
Stream-like movements of ocean water far below the ocean surface.
Waves are made of what two main components
crests and troughs
True or False
Do surface currents flow like rivers in distinct patterns around the Earth.
True
True or False
Does the Australlia Current flow Northward from the Great Barrier Reef?
False, It flows Southward!
True or False
Warm water currents begin near the equator and carry warm water?
True!
What are deep currents controlled by?
Deep currents are mainly controlled by increases in water density.
What is a crest?
A crest is the highest point!
What creates surface currents?
Global winds blowing across the Earth’s surface!
What current is Nemo and his friends on in the movie?
The East Australian Current
Do surface currents effect climate?
yes
True or false
Temperature and salinity do not affect the density of ocean water
False
What is a Trough?
trough is the lowest point.
What happens because of the Coriolis Effect?
Currents in the Northern Hemisphere turn clockwise while currents in the Southern Hemisphere turn counterclockwise.
Near what continent does the East Australian Current
Australia
True or false
Cold-water currents create warmer climates in coastal areas.
False, they create colder climates.
What happens as you go deeper into the ocean?
1. The water temperature becomes colder as the depth increases
2. The water temperature becomes warmer as the demth increases
#1 is correct
What is a wave length?
A wavelength is the distance between two adjust crests or troughs.
Surface currents are controlled by what four factors?
Global winds, the Coriolis effect, continental deflections, and the water temperature.
How wide and deep is the current?
almost 100 km wide, and more than 1.5 km deep
What causes changes in the atmosphere that disrupt the climate in many parts of the world.
Surface currents warm and cool.
True or flase
Less- denses water always flows on the water.
True
What is a wave height
Wave height is the vertical distance between a waves crest and its trough.
