Each member of the group will go to the
website listed on task card #1
Complete the task cards in order.
Every student will answer the questions from
the task cards on the lab sheet in the
Research It! section.
1. Go to
https://bit.ly/3aY5wMv
Use the website to answer
questions on the next card.
You will need to watch the video
and read the background info.
Density differences in
ocean water drive the
global conveyor belt. This
global circulation system
is also called
thermohaline circulation.
1. When broken down into its root
words, what does “thermohaline”
mean?
The global conveyor belt
carries water and heat
energy across the globe.
2. What is the difference in how
the conveyor belt moves water
in the tropics compared to the
Arctic?
3. What forces are responsible
for tidal currents and are they
predictable?
Explore It! Station Directions
One member of the group will read the task
cards in order. The group will be responsible
for completing each of the tasks that are
being read.
Each member of the group will then write
their conclusions down on the lab sheet in
the Explore It! section.
Use the diagrams at the
station for this activity.
1. On your lab sheet compare and
contrast the two different
diagrams.
During the day the Sun heats up the
Earth unequally. Parts of the Earth get
more direct sunlight and parts get very
little sunlight.
1.
How do you think the Sun’s energy
impacts ocean currents and wind?
A convection current is the
transfer of heat in within a
liquid or gas.
The Sun’s energy heats the oceans and
land. The energy is released in the form
of convection currents into other parts
of the ocean and into the atmosphere.
The ocean has convection currents that
cause channels of water to flow in a
predictable direction throughout the
worlds oceans.
The gases in the atmosphere move in
the form of wind due to energy that is
released from the land and oceans.
The ocean has a greater
heat capacity than the land
meaning that it can hold
more heat than the land.
The oceans overall temperature will not
change as drastically as the land will.
1.
List an example of how the land can
have a dramatic change in
temperature throughout the day.
Use the diagrams at the
station for this activity.
During the day the land heats up
much quicker than the ocean. The
energy is released in the form of
heat and the cooler air moves in
from the ocean which causes a
sea breeze.
Use the diagrams at the
station for this activity.
During the evening the land has
released most of it’s energy and is
much cooler than the ocean. The
heat from the ocean rises up and
pulls cooler air from the land to
form a land breeze.

Read It! Station Directions
Each member of the group will read the
passage and answer the questions from the
task cards on the lab sheet in the Read It!
section.
It is important to remember that the answers
will come directly from the reading passage.
Convection Currents
Convection currents in the atmosphere carry heated air up and
drop cooler air down toward the earth’s surface. This is due to
the differences in density of warm and cold air. This continuation
of air movement affects air pressure, winds, and weather on
earth.
If there is sunlight, there will be wind. The wind is a by-product of
solar energy. Approximately 2% of the sun’s energy reaching the
earth is converted into wind energy. The surface of the earth
heats and cools unevenly, creating atmospheric pressure zones
that make air flow from high-pressure to low-pressure areas. Any
difference in pressure will cause wind, but the greater the
difference, the stronger the wind.
The direction that wind takes is influenced by the rotation of the
earth. On a non-rotating earth, the wind would move in a
straight path from a high to a low-pressure area. Because of the
earth’s rotation, the wind is deflected from this straight path and
moves to the right in the Northern Hemisphere and to the left in
the Southern.
Local winds are those that affect a comparatively small area.
These winds are often caused by heat transferred through
convection. Direct radiation from the sun does little to heat the
air. It is warmed chiefly by heat radiated from the earth. Intense
local heating of the land causes air directly above to become
greatly heated and to expand. As a result, some of the air aloft
flows away, lowering the pressure over the heated area and
increasing the pressure around it. The cooler, heavier air near
the earth then flows to the heated area.
In mountainous areas, winds tend to blow uphill during the day
because the mountainside is heated more than the valley below
it. At night, when the mountainside cools, the wind blows
downhill. In summer, breezes tend to blow from oceans or large
lakes to the warmer land during the day. They blow from the
land at night, when the land cools.
Convection is a big part of how hot and cold air moves around
our planet.

A. Eliminate Mercury, Venus and
Mars
B. Eliminate all plant life
C. Eliminate the moon

does air flow near a

shoreline
B. Wind is not impacted by day and

C. From the ocean to the land
D. From the land to the ocean
