About This Chapter

Allow us to help you prepare for the Earth and Space Sciences content area test of the Praxis. Review glaciers, oceans and islands with engaging video lessons and short quizzes for self-assessment.

Praxis Earth and Space Sciences: Glaciers & Oceans - Chapter Summary

What causes tsunamis, island formation or sea level changes? Our video lessons can help you study ocean characteristics, circulation and tides. You can also review information about glaciers through this chapter. Find out about the various types and their movements, in addition to learning about erosion and deposition. When you've finished these lessons, you should be able to answer test questions about the following topics:

  • Glacial types, movement, erosion, change and deposition
  • Ocean structure, circulation, properties, waves and tides
  • Topography of the sea floor
  • Tsunami causes and effects
  • Formation and gradual change of islands
  • Estuary roles
  • Origin and deposition rates of marine sediments
  • Alterations of sea levels
  • Photosynthesizers and light penetration in oceans
  • Nutrient flow

The video lessons in this chapter can help you refresh your memories of these crucial topics, and the quizzes offer you experience with the types of questions you may find on the test.

What Are Glaciers? - Definition, Types & Processes

1. 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.

Glacier Movement: Definition & Process

2. Glacier Movement: Definition & Process

Glaciers are mountains of ice that move. This movement is usually a combination of processes that include internal plastic deformation and basal sliding. Learn about these processes and factors that increase glacial flow rates.

Glacial Erosion: Definition, Processes & Features

3. Glacial Erosion: Definition, Processes & Features

Glaciers are huge blocks of ice that move along the landscape, carving distinct features along the way. Learn about the glacial erosion processes, plucking and abrasion, and the features they create, including cirque, horns, arĂȘte and roche moutonnee.

Glacial Deposition: Definition & Results

4. Glacial Deposition: Definition & Results

As glaciers move and retreat, they push and drop rocks and sediments in a process known as glacial deposition. Learn about this glacial process and the interesting landforms that result from it, including moraines, erratics and drumlins, in this lesson.

Ocean Circulation: Patterns & Effect on Climate

5. 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.

Properties of Ocean Water

6. 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.

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.

What Are Tides? - Causes & Effects

8. 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.

The Causes & Effects of a Tsunami

9. The Causes & Effects of a Tsunami

A tsunami is a powerful series of waves that result due to an abrupt disturbance, such as an earthquake. Learn how tsunamis form and grow and discover the devastating effects they can have on people and the environment.
