Ch 46: Praxis General Science: Earth's Bodies of Water

About This Chapter

Learn from this chapter's text and video lessons on the Earth's bodies of water so you can provide accurate answers on the Praxis General Science examination. The chapter's quizzes can also help you prepare to earn the teaching endorsement.

Praxis General Science: Earth's Bodies of Water - Chapter Summary

Study the ways in which the Earth's bodies of water form, and examine some of their many types and features through this chapter's online text and video lessons. For example, you can learn about different kinds of ocean waves, including tsunamis and tidal waves. Explore the water cycle from precipitation through evaporation, and discover the function of groundwater. Check out these and other facts in preparation for passing the Praxis General Science examination for a teaching certification. The information presented in this chapter can help you to:

  • Understand the biodiversity of oceans
  • Explain the water cycle's processes
  • Discuss the distribution of the Earth's water
  • Identify the Earth's major oceans and ocean zones
  • Understand waves' effects on erosion
  • Contrast passive and active continental margins
  • Explain the formation of ocean basins and ocean ridge systems
  • Define glaciers and groundwater systems

This flexible mode of education will allow you to learn all about the Earth's bodies of water as your schedule allows. In fact, you can access these text and video lessons online 24/7. Just click to pause and restart the lessons as you jot down information or memorize on-screen graphics. You can also refer to the written transcripts that have important keywords, and utilize the worksheets and self-assessment quizzes as you absorb this chapter's material. When you sit for the Praxis General Science examination, you can apply your acquired knowledge.

Praxis General Science: Earth's Bodies of Water Chapter Objectives

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!

Chemical Composition & Physical Attributes of Fresh, Brackish & Salt Water

4. Chemical Composition & Physical Attributes of Fresh, Brackish & Salt Water

Discover the differences between fresh, brackish, and saltwater. Learn about their chemical and physical features. Afterward, see how well you know the differences by taking a quiz.

Oceans: Facts & Information

5. 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

6. 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

7. 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.

Characteristics of Different Ocean Zones

8. Characteristics of Different Ocean Zones

The oceans can be divided into horizontal and vertical zones. These divisions help us better understand the characteristics of these vast bodies of water. Learn what these zones are in this lesson.

Active & Passive Continental Margins

9. 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

10. 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

11. 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.

What Are Glaciers? - Definition, Types & Processes

12. What Are Glaciers? - Definition, Types & Processes

Learn about the two major types of glaciers: continental and alpine glaciers. These glaciers shape the landscape around them and affect our everyday lives, even if the nearest glacier is thousands of miles away.

Groundwater System: Definition & Geological Role

13. Groundwater System: Definition & Geological Role

Surprisingly, most of Earth's liquid freshwater is not where you might think! In this video lesson, you will learn about groundwater, as well as the important roles it plays in sustaining life and shaping Earth.
