Transcript of Geologic Features of Glaciation. Horn Mountain peak formed by glacial erosion.
Horn
• Mountain peak formed by glacial erosion
Lateral Moraine
• Narrow band of sediment along the outer sides of an alpine glacier formed by erosion of valley walls
Medial Moraine
• Narrow band of sediment within an alpine glacier formed when two lateral moraines meet
End Moraine
• Mound of unsorted sediment at the end of a glacier formed by glacial advancement which bulldozes sediment to a ridge
Ground Moraine
• Loose sediment found along flat terrain once covered by a glacier; formed when sediment is left behind by a retreating glacier
Kame
• Hill of sorted glacial deposits found on ground moraines; formed by deposits made by a retreating glacier
Tributary Glaciers
• Small glacial rivers that eventually join a valley glacier; due to glaciers forming in small alpine regions
Braided Stream
• Stream of meltwater that flows towards an outwash plain; formed as glacier melts but rivers are choked with sediment
