• Content Area: Science
• Grade Level: 5
• Summary: The purpose of this instructional PowerPoint is to help the
students understand the physical characteristics and the chemical makeup
of the atmosphere, and how it influences the surface processes and life on
Earth.
• Learning Objective: websites that contains facts about the ocean and the
effects it has on weather and climate, students will need to interpret the
material within the website to answer the questions within the power point
with 100 percent accuracy.
• Content Standard: SPI 0507.8.1 Describe the effects of the oceans on
weather and climate.
Accomplishment:3. Research and information fluency
Students apply digital tools to gather, evaluate, and use information.
b. Locate, organize, analyze, evaluate, synthesize, and ethically use
information from a variety of sources and media
FACTS
Go to this website to explore important
facts on the Oceans and climate NASA's
Climate Kids :: What is happening in the
ocean?
Why is the Ocean Important?
The ocean covers 70% of Earth's
surface
The ocean contains about 97% of all
the water on Earth.
One big part of its role is to soak up
energy (heat) and distribute it more
evenly around the Earth. Another part is
to soak up CO2.
WHAT ROLE DOES CO2
PLAY?
Carbon Dioxide (CO2):
•
Carbon dioxide is entirely made up of carbon and
oxygen and accounts for 54.7% of the major
greenhouse gases from peoples activities. CO2
originates from a natural processes such as
respiration and volcano eruptions though it can just
as well originate from human activities such as the
burning of gasoline and other fossil fuels used to
produce electricity and heat buildings.

THE OCEAN AFFECTS CLIMATE & WEATHER
Majority of the sun’s radiation is absorbed by the ocean
The ocean acts a as massive, heat-retaining solar panel. Earth’s atmosphere also plays a part in this process,
helping to retain heat that would otherwise quickly radiate into space after sunset
Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain
and storms that are then carried by trade winds, often vast distances.
Weather patterns are driven largely by ocean currents
Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward
the poles and cold water from the poles back to the tropics.
Currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s
surface.

SUMMARY
The world’s ocean is crucial to heating the planet. The ocean doesn't just
store solar radiation; it also helps to distribute heat around the globe. When water
molecules are heated, they exchange freely with the air in a process called
evaporation. . Ocean currents act much like a conveyer belt, transporting warm
water and precipitation from the equator toward the poles and cold water from
the poles back to the tropics. Therefore, currents regulate global climate, helping
to counteract the uneven distribution of solar radiation reaching Earth’s surface.
Without currents, regional temperatures would be more extreme super hot at the
equator and frigid toward the poles, and much less of Earth’s land would be
habitable.
