Oceans Interactions
Oceans 05
How does the ocean impact the other spheres
of Earth?
OBJECTIVES
• At the end of this lesson you should be able
to:
• describe interactions of oceans with other
spheres
• discuss how ocean waves affect a coastline
• describe how oceanic conditions in Florida
impact human behavior
Where did the sand come from?
From undersea mountains and the seafloor
From rocks on the ocean floor
From distant mountains and landforms
Earth’s Spheres
• Hydrosphere
• Biosphere
• Atmosphere
• Geosphere
• Cryosphere
Geosphere
List ways in which the ocean and geosphere interact
Geosphere
• Beach nourishment projects protect natural
shoreline environments.
• Many in Florida
Biosphere
• Organisms in the ocean depend upon each
other
• Life in the ocean plays a part in regulating
atmospheric gases and parts of the rock cycle.
• Biodiversity is threatened .
We will look at Coral Reefs, Intertidal Zones and
Deep Sea Organisms
Coral Reefs
•
•
•
•
How do they form?
Coral skeletons
Prevents erosion of shoreline
Affected by human activities
– Coral bleaching due to increase in ocean
temperature
Interactions with atmosphere, geosphere and
biosphere
Intertidal Zones
• Organisms here are adapted to daily changing
conditions: wave action, rising tides, falling
tides.
• They help scientists learn how tides affect the
biosphere.
Deep Sea Organisms
• These organisms deal with lack of sunlight and
great pressure.
Coelacanth- The Living Fossil Fish
– Teaches scientists about evolution. Thought it died
out 65 million years ago. In 1938 found living off
Madagascar
Recreation
Human Behavior
• Economic activities: encourage people to live
and work near coast.
• Shipping – transport of goods, local jobs
Hurricane
• Massive tropical cyclone that spins around a
low pressure center.
– Can lead to storm surges, catastrophic flooding,
loss of life, destruction and billions of dollars in
losses
Climate and Atmosphere
Do you notice a difference between the areas of ocean
in the Northern Hemisphere versus the Southern
Hemisphere?
How does this difference affect climate?

Introduction: Identify the ocean resource. Introduce how the resource
affects other Earth spheres, both positively and negatively, if appropriate.
Multimedia: Use at least three images, diagrams, videos, or audio clips.
Data: Describe how the ocean resource affects the rest of the
hydrosphere, as well as the geosphere, cryosphere, biosphere, and
atmosphere.
Conclusion: Describe its overall value to society. Justify the protection of
the resource by writing a summary paragraph explaining how the
endangerment of that resource can cause detrimental effects locally or
globally. Describe at least three ways to protect the resource.
Resources: List at least three reliable resources from your research,
including those for images, diagrams, videos, and audio clips.
