User:PolishChicken37/Glacial landform

Plan

 * add till definition to depositional landforms & make given descriptions more robust
 * add to beginning intro/description, once edits on rest of article are complete (make it summarize the rest of the article and accurately portray what is to come)
 * add more examples of glacial landforms, and not just from North America/Europe

Done:


 * erosional landforms - added definitions and such
 * depositional landforms - added definitions and such

Erosional Landforms [edit] Italics = my edits to the original article (change later when ready to post) -
Erosional landforms

As the glaciers expand, due to their accumulating weight of snow and ice they crush, abrade, and scour surfaces such as rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
 * Striations: grooves and indentations in rock outcrops, formed by the scraping of small sediments on the bottom of a glacier across the Earth's surface. The direction of striations display the direction the glacier was moving.
 * Cirque: Starting location for mountain glaciers, leaving behind a bowl shaped indentation in the mountain side once the small glacier has melted.(add geology book citation already in the article)
 * Cirque stairway: a sequence of cirques
 * U-shaped, or trough, valley: U-shaped valleys are created by mountain glaciers. When filled with ocean water so as to create an inlet, these valleys are called fjords.
 * Arête: spiky high land between two glaciers. If the glacial action erodes through, a spillway (or col) forms
 * Horn: a sharp peak connecting multiple glacier intersections, made up of multiple arêtes.
 * Valley step: an abrupt change in the longitudinal slope of a glacial valley
 * Hanging Valleys: Formed by glacial meltwater eroding the land partially, often accompanied by a waterfall.
