Why is Europe warmer
than Northern Canada?
By Rebecca S.
Introduction
Northern Canada and Europe are located on the
same line of latitude, but they have completely
different climates and weather patterns. Did you
ever wonder why this was? It all has to do with a
very important current, the Gulf Stream.

What is the Gulf Stream?
The Gulf Stream is the
second largest current
system in the world, and
the largest system in the
Atlantic Ocean. It is QuickTime™ an d a

Florida and ends in
northwest Europe. The
average temperature of
the Gulf Stream is 77
degrees Fahrenheit, which
keeps the air temperature
of the earth warmer in
some places.
How does the Gulf Stream
work?
Winds from the Artic cool the
surface water in the Atlantic. The
cool water becomes denser and
saltier, so it sinks to the ocean
floor. Then, the new surface water

the warm water in the Gulf of
Mexico to the Atlantic to replace
the cold water that moved toward
the equator. The Gulf Stream is
classified as a convection current
because the cold water sinks and
the warm water rises.
What is a Convection
Current?
Convection currents are
caused by the expansion of a

less dense, warmer liquid
rises and the denser, cold
liquid sinks. The Gulf Stream
is a convection current.
Specific Heat Capacity of
Water
The quantity of heat required to raise the temperature of a
substance by one degree Celsius is known as the heat
capacity of water. Every substance has a different heat
capacity; however, water has a very high heat capacity. Water
takes a long time to warm in the sun, but it also takes a long
time to cool during the night. Water resists change in
temperature because of its high heat capacity. The Gulf
Stream keeps the water warm, which helps the climate in some

How does the Gulf Stream
impact the Climate in
Europe?
The Gulf Stream carries
warm waters to the Atlantic
near Europe and stays
warm until it starts to cool.
