Ocean Surface Currents (Slides 1 & 2)
Surface currents are controlled by four factors
global winds, the Coriolis effect, continental deflections, and the water temperature.
The East Australian Current does flow along the...
East coast of Australia
What would happen if Earth's surface were covered only with water?
Currents would travel in a fixed pattern across the Earth
Blank- are stream-like movements of ocean water far below the ocean surface.
Deep currents
Waves are made of two main components such as
crests and troughs.
Stream like movements of water that occur at or near the surface of the ocean are called
Surface Currents.
The real East Australian Current is much __ then in the movie
bigger
Warm water currents begin near the...
Equator
what affects the density of ocean water.
Temperture and salinity
A blank is the highest point and the blank is the lowest point.
Crest, trough.
The rotation of the Earth causes surface currents to move in
Curved paths
Speeds in the core of the EAC are among the...
Strongest in the South Pacific.
When currents meet landforms they...
Change Directions.
Deep currents are mainly controlled by
increases in water density.
A ___ is the distance between two adjust crests or troughs.
wavelength
Global winds blowing across the Earth’s surface create
surface currents.
How wide and how deep is the current?
100 km wide, and more than 1.5 km deep
Some surface currents warm and some cool coastal areas which affects the climate. around what time
year round
Cold air chills the water molecules at the surface, causing them to
move closer together.
blank is the vertical distance between a waves crest and its trough.
wave height
Coriolis Effect, currents in the Northern Hemisphere turn what direction
Clockwise
How much does the East Australian Current transports?
40 million cubic metres of water southward per second
Surface currents ___ affect the climate in many parts of the world.
Greatly
The denser water moves along the ocean floor and eventually travels toward the
equator in a deep current.
A wave is defined as a
transfer of energy.
