ocean surface currents
what are the four main ocean currents
north equatorial, gulf stream, north atlantic, canary
what patterns do currents make
circulary
what is an example of a deep current
North Atlantic Deep Water and Antarctic Bottom Water
what causes waves
wind, suns radiation, gravity, earths rotation
what is a current
a circular pattern
what is an ocean current
driven by global wind systems that are fueled by energy from the sun
How do currents shape global climate patterns
act much like a conveyor belt
What are deep currents caused by
differences in water density
why are waves important
the motions they create perform a vital role in transporting energy around the globe and shaping the coastlines
What are the patterns of surface currents called
gyres
where is Tsushima current
the northeastward-flowing branch of the Kuroshio along the west coast of Japan
how many currents are there
two
what is the difference between surface currents and deep currents
Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy
what would happen if there were no waves
energy cannot do anything
What causes the pattern of ocean currents
wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents
what causes a ocean current
The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast
What is the Gulf Stream current
an intense, warm ocean current in the western North Atlantic Ocean
How do deep currents affect the oceans
regulation of local weather conditions and temperature extremes, stabilization of global climate patterns, cycling of gases, and delivery of nutrients and larva to marine ecosystems
whats the difference in waves and currents
Waves are created by the wind and then radiate in all directions away from the disturbance. Currents represent the movement of water particles which is controlled by winds and density differences
What are the 5 main ocean currents
North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres
how do surface currents affect climate
currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface
What type of current is the California Current
eastern boundary current
what causes deep currents
changes in water density
what causes tsunamis
earthquakes on converging tectonic plate boundaries
What are surface currents
caused mainly by winds but not daily winds
