Thanks for your great question! The Atlantic
Ocean plays a large role in controlling the
climate of eastern North America. An ocean
current is the continuous movement of seawater in
a certain direction. The ocean currents are
caused by winds blowing on the water surface and
by changes in the temperature and salinity
(saltiness) of the ocean water. If water is
saltier or colder it will sink because it’s
heavier, and this sinking sets up a type of
circulation known as thermohaline
circulation. The combination of thermohaline
circulation and wind direction plays a role in
setting up the general directions that ocean
currents are flowing. Off the coast of eastern
Canada, the most important ocean current is known
as the Labrador current.
The Labrador Current flows southwards from the
arctic along the coasts of Labrador, Newfoundland,
and Nova Scotia, which are in eastern Canada. This
current brings cool
temperatures to eastern Canada and also carries
icebergs from the Greenland ice sheets southward.
Near Nova Scotia, the Labrador Current runs into
the Gulf Stream, which is a northward flowing
current that brings warm waters along the east
coast of the United States from Florida to Canada.
When these two currents run into each other they
sometimes create a lot of fog in a part of Canada
known as the Grand Banks.
I hope this answers your question!
