Ch 60: Life Cycle of Glaciers

About This Chapter

Study these engaging environmental science lessons to review the life cycle of glaciers. These lessons are particularly beneficial to anyone who needs to prepare for an upcoming exam and strengthen knowledge of glaciers.

Life Cycle of Glaciers - Chapter Summary

This convenient environmental science study resource breaks down the life cycle of glaciers and helps you review relevant glacier terminology and processes. As you work through the chapter, you'll study glacial formation and movement, as well as glaciation, deposition and erosion. Our expert science instructors will also explain the effect that the Ice Age had on glaciers. By the end of the chapter, you should be able to:

  • Identify different types of glaciers and explain how they move
  • Determine how wastage and accumulation affect the formation of glaciers
  • Recognize the features of glacial erosion
  • Define glacial deposition
  • Understand how the Ice Age affected glaciers and formed pluvial lakes
  • Analyze glaciation causes

Following each lesson is a short quiz to help you gauge your understanding of important glacier vocabulary and concepts. You can keep track of your quiz scores and progress throughout the chapter on your course dashboard. This feature also allows you to jump to specific lesson topics. Lessons can be studied as many times as needed, and you can use any device that has in Internet connection to access the chapter. This flexibility allows you to study wherever and whenever it's convenient.

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.

Causes of Glaciation

2. Causes of Glaciation

Glaciation refers to being covered with glaciers. Learn about the theories behind glaciation, including the changing continental positions and the Milankovitch theory, which points to three orbital variations: eccentricity, obliquity and precession, in this lesson.

The Effect of Ice Age Glaciers: Formation of Pluvial Lakes

3. The Effect of Ice Age Glaciers: Formation of Pluvial Lakes

Ice age glaciers caused erosion and deposition, which resulted in unique features such as horns, cirques, lakes, U-shaped valleys, moraines and drumlins. Indirect effects include pluvial lakes, isostatic depression and a change in sea level.

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.

Glacial Erosion: Definition, Processes & Features

5. 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.

The Effect of Accumulation & Wastage on Glacier Formation

6. The Effect of Accumulation & Wastage on Glacier Formation

Glaciers grow through a process called accumulation and waste away through a process called wastage, or ablation. Learn about these processes and how they are used to determine the health, or mass balance, of a glacier.

Glacier Movement: Definition & Process

7. 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.
