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 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.
