Ch 57: Coastal Processes - ORELA Middle Grades General Science

About This Chapter

Let us help you study for the ORELA Middle Grades General Science assessment by providing this in-depth look at coastal processes. Fun video lessons and short quizzes are available to enhance your preparations for the exam.

Coastal Processes: ORELA Middle Grades General Science - Chapter Summary

When studying for the ORELA Middle Grades General Science assessment, it's good to get familiar with the topics you haven't explored in some time. The video lessons revisit coastal processes to ensure you're ready to answer questions that address the following:

  • Identifying types and features of waves as well as their effect on erosion
  • Examining the definition, types, causes and processes of mass wasting
  • Understanding the characteristics of shorelines and beaches
  • Exploring the contributing factors of longshore transport
  • Analyzing the effects of coastal erosion and deposition on shoreline features
  • Discussing the causes and effects of changes in sea level
  • Using hard stabilization on shorelines and examining alternatives to hard stabilization

Subject matter experts make the process of getting reacquainted with coastal processes simple. The lessons are entertaining and informative, ensuring that you fully comprehend the concepts as you prepare for the exam.

Coastal Processes: ORELA Middle Grades General Science Objectives

In Oregon, the ORELA assessment has been replaced by the NES Middle Grades General Science assessment. The purpose of this exam is to ensure that educators in the state have the knowledge needed to acquire licensure and teach general science to students in middle grades. There are 150 multiple-choice questions on this computer-based test. Passing requires a minimum score of 228.

The assessment is broken into four content domains that explore the nature of science, physical science, life science, and earth and space science. This chapter's topics are found in the earth and space science content domain which constitutes approximately 25% of the total test. In addition to watching the video lessons, you can take quizzes and a chapter exam to reinforce the coastal processes concepts you study. If you have any questions about lesson topics, feel free to submit them to our experts.

Waves: Types, Features & Effect on Erosion

1. 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.

Mass Wasting: Definition, Types, Causes & Processes

2. Mass Wasting: Definition, Types, Causes & Processes

Mass wasting or mass movement is the movement of a large mass of rock, soil and debris downward due to the pull of gravity. Learn about the process of mass wasting, the factors that must be present to trigger it and the different types.

Characteristics of Shorelines & Beaches

3. 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.

Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

4. 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.

The Effects of Coastal Erosion on Shoreline Features

5. The Effects of Coastal Erosion on Shoreline Features

Shorelines constantly change due to the pounding of waves that erode coastal structures. Learn about shoreline features that are formed through coastal erosion, such as wave-cut cliffs, wave-cut platforms, sea arches and sea stacks.

The Effects of Deposition on Shoreline Features

6. The Effects of Deposition on Shoreline Features

Shorelines constantly change due to the depositing of sand and sediment, which is a process known as deposition. Learn about shoreline features that are created by deposition, such as spits, baymouth bars, tombolos and barrier islands.

Changes in Sea Level: Causes & the Effect on the Environment

7. Changes in Sea Level: Causes & the Effect on the Environment

Sea level rise is a natural process, but recent trends are concerning because it is increasing at an alarming rate. In this lesson, you'll learn what causes changes in sea level and what effect rising sea level has on humans and the environment.

Using Hard Stabilization on Shorelines

8. Using Hard Stabilization on Shorelines

Shorelines erode under the force of waves. This changes beaches and can result in property damage. Learn about hard stabilization structures, such as groins, breakwaters and sea walls and how they are used to protect against erosion.

Alternatives to Hard Stabilization: Beach Nourishment & Relocation

9. Alternatives to Hard Stabilization: Beach Nourishment & Relocation

Coastal areas are subject to erosion from waves and wind. Hard stabilization slows erosion but disturbs the aesthetic beauty of the shore and alters the natural ecosystem. Learn here about alternatives, including beach nourishment and relocation.
