Ch 52: General Science: Oceans

About This Chapter

The AEPA General Science exam is now a National Evaluation Series (NES) test. This study guide will get you ready for questions about oceans on the NES General Science exam.

AEPA General Science: Oceans - Chapter Summary

These lessons and quizzes are a fast and easy way to get up to speed for the AEPA General Science exam. You'll review everything you'll need to know about oceans, including tides, marine organisms and the characteristics of different types of shorelines. The lessons also cover the following topics:

  • Passive and active continental margins
  • Ocean basins and ridges
  • Properties of ocean water
  • Ocean circulation patterns and their effect on climates
  • Types of waves and their impact on erosion
  • Longshore transport

Each video lesson is less than ten minutes long, so you can quickly catch up on the topics you need to review. Use the video timeline tags to skip topics you already know and rewatch those you are a bit rusty on. Our expert instructors are here to answer any questions you might have about the lesson material.

AEPA General Science: Oceans Objectives

This chapter will help you with questions in the earth and space science section of the AEPA General Science exam, which makes up about 19% of the score. For the ocean-related questions on the test, you'll need to demonstrate your understanding of the characteristics and processes of ocean systems, coastal processes and the relationship between oceans and the atmosphere.

The AEPA General Science exam is a part of the certification process to become a science teacher in Arizona. Questions are all multiple-choice, and will be answered on a computer. The exam takes three hours to complete and has 150 questions.

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.
