Ch 51: CEOE Middle Level Science: The Hydrosphere

About This Chapter

Reinforce what you know about bodies of salt- and freshwater using our video lessons and self-assessment quizzes. These earth science topics are addressed on the Certification Examinations for Oklahoma Educators (CEOE) Middle Level Science exam.

CEOE Middle Level Science: The Hydrosphere - Chapter Summary

The lessons in this chapter are designed to provide brief but detailed overviews of seawater and freshwater systems, ocean characteristics and the water cycle. You will go over specific features, formations and processes relating to various bodies of water. A thorough review of this material will prepare you to answer these types of questions on the CEOE Middle Level Science exam:

  • Relating details about water-based ecosystems
  • Explaining the water cycle
  • Detailing how water is distributed over the Earth
  • Understanding Archimedes' Principle
  • Calculating hydrostatic pressure
  • Describing flow rate and the equation of continuity
  • Summarizing facts about oceans, waves, ocean basins and ocean circulation
  • Identifying active and passive continental margins
  • Discussing the formation and characteristics of the oceanic ridge system

Instructors guide you easily through the lessons, using easy-to-follow explanations and illustrated examples to make learning fun and engaging. The accompanying quizzes allow you to assess what you've learned and measure your preparedness for the CEOE Middle Level Science exam by using the same multiple-choice format found on the actual exam.

Ecosystems of Oceans and Freshwater: Biological Diversity and Water

1. Ecosystems of Oceans and Freshwater: Biological Diversity and Water

In this lesson, you'll learn about the biodiversity of ecosystems based on water. You will discover that marine, freshwater and a mixture of salt and freshwater create very different ecosystems, which in turn influence the amount of biodiversity that is found in these habitats.

The Water Cycle: Precipitation, Condensation, and Evaporation

2. The Water Cycle: Precipitation, Condensation, and Evaporation

This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.

The Distribution of Water on Earth

3. The Distribution of Water on Earth

Water covers most of Earth but in a variety of forms. In this video lesson you will learn about how water is distributed on Earth, though you may be surprised to find out just how little of it we can access!

Buoyancy: Calculating Force and Density with Archimedes' Principle

4. Buoyancy: Calculating Force and Density with Archimedes' Principle

Knowledge of the buoyant force is important when trying to understand why some objects float while other objects sink. In this lesson you'll learn about this unique force and how we apply it to various situations using Archimedes' Principle.

Hydrostatic Pressure: Definition, Equation, and Calculations

5. Hydrostatic Pressure: Definition, Equation, and Calculations

This video lesson will introduce you to hydrostatic pressure in a liquid, as well as provide examples for how to calculate the liquid's pressure at a given depth.

Fluid Mass, Flow Rate and the Continuity Equation

6. Fluid Mass, Flow Rate and the Continuity Equation

Fluids rarely stay put, so we need to understand how they move. In this lesson, you will learn about how the movement of fluids is influenced by the space it passes through, as well as see examples of how to calculate aspects of this movement.

Oceans: Facts & Information

7. Oceans: Facts & Information

Over fifty percent of the world's population lives near a coastline. The oceans of the world affect our everyday lives, from recreation to resources, to climate. Learn some fun facts about this unique feature of our planet!

Ocean Circulation: Patterns & Effect on Climate

8. Ocean Circulation: Patterns & Effect on Climate

The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.

Waves: Types, Features & Effect on Erosion

9. Waves: Types, Features & Effect on Erosion

There are different types of ocean waves, including wind waves, tsunamis and tidal waves. Learn the features of waves and how their erosive effect creates the unique features found on the shoreline.

Active & Passive Continental Margins

10. Active & Passive Continental Margins

Continental margins are areas that separate the continental crust and oceanic crust. Discover the differences between the tectonically active continental margins and the relatively quiet passive continental margins.

Ocean Basins: Definition, Formation, Features & Types

11. Ocean Basins: Definition, Formation, Features & Types

Ocean basins are those areas found under the sea. They can be relatively inactive areas where deposits of sediment slowly collect or active areas where tectonic plates meet. Learn how ocean basins form and about features such as oceanic ridges and trenches.

Oceanic Ridge System: Formation & Distribution

12. Oceanic Ridge System: Formation & Distribution

The oceanic ridge system is a continuous underwater mountain range with parts found in every ocean of the world. The ridge system is created when magma rising between diverging plates of the lithosphere cools and forms a new layer of crust.
