In this chapter, you'll learn the answers to questions including:
- How are glaciers classified and formed?
- How do accumulation and wastage affect glacier formation?
- What occurs during glacial erosion processes?
- What is the definition for glacial deposition?
- How are pluvial lakes formed?
- What are the major causes of glaciation?
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.
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.
3. 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.
4. 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, arête and roche moutonnee.
5. 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.
6. 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.
7. 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.
