Ch 48: Praxis Biology & General Science: Earth and Space: Oceanography

About This Chapter

Let us help you review ocean chemistry, marine organisms, wave types and more. This chapter's video lessons and self-assessment quizzes can prepare you to successfully answer these types of oceanography questions on the Praxis II Biology and General Science exam.

Praxis II Biology & General Science: Oceanography - Chapter Summary

Characteristics of the ocean's waves, tides and ridge systems are just some of the topics covered in this chapter's video lessons. If you need to also review beach drift and longshore currents in time for the Praxis II Biology and General Science exam, there are lessons on these topics as well. Find out what else is covered in this chapter by checking out the list below:

  • Active and passive continental margins
  • Ocean basins
  • Oceanic ridge systems
  • Properties of ocean water
  • Ocean chemistry
  • Types of marine organisms
  • Ocean circulation
  • Characteristics of shorelines and beaches
  • Types and features of waves
  • Factors of longshore transport
  • Causes and effects of tides

Each of the lessons includes a short, engaging video taught by a knowledgeable instructor. There are also transcripts containing links to text lessons that outline important vocabulary terms and self-assessment quizzes you can use to gauge how much study time you'll need to put in before exam day.

Objectives of the Praxis II Biology & General Science: Oceanography Chapter

Some states' teacher licensing boards require passing scores on the Praxis II Biology and General Science exam. This ensures that aspiring high school general science or biology teachers possess the subject area knowledge needed to succeed in the classroom.

The video lessons and quizzes included in this chapter can help you answer questions appearing on the Earth and Space Science section. This part of the test includes approximately 12 of the exam's 120 multiple-choice questions and requires you to be familiar with the physical and chemical characteristics of the ocean, as well as its geological features and biological makeup.

Active & Passive Continental Margins

1. 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

2. 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

3. 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.

Properties of Ocean Water

4. Properties of Ocean Water

Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.

Types of Marine Organisms

5. Types of Marine Organisms

Many marine organisms thrive under the surface of the ocean. Learn about the biodiversity of the oceans, from the microscopic plankton to the enormous whales, and how these organisms adapt to their oceanic environment.

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.

Characteristics of Shorelines & Beaches

7. Characteristics of Shorelines & Beaches

Shorelines and beaches are constantly changing due to forces, such as waves, winds and currents. Learn about characteristics of shorelines, including headlands, bays, beach berms, sand dunes, spits, tombolos, barrier islands and lagoons.

Waves: Types, Features & Effect on Erosion

8. 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.

Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

9. Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

The longshore transport is the process responsible for the movement of sand and sediment along the coastline. Sand and other particles are transported with the help of the longshore current and beach drift. Learn how these factors shape shorelines.

What Are Tides? - Causes & Effects

10. What Are Tides? - Causes & Effects

Tides rise and fall under the influence of the gravitational pull of the moon and sun. Learn about different tides, why they are predictable and their effects on coastal regions of the world.
