Erosion and Deposition: Glaciers Only

Erosion

The process by which wind, water, ice, or gravity transports soil and sediment from one location to another

climate

Overall weather in an area over a long period of time

Gravity

A force of attraction between objects that is due to their masses.

glacier

Any large mass of ice that moves slowly over land

Moraine

a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity.

U-shaped valley

A flowing glacier scoops out a U-Shaped valley

Striations

Long parallel scars in rocks carved by rock fragments being dragged across them by a glacier (erosional)

Horn

A pyramid-like peak formed by glacial action in three or more cirques surrounding a mountain summit.

outwash plain

the flat area at the end of a glacier where meltwater flows and deposits sediment

glacial till

sediment deposited directly by a glacier

Drumlin

A long mound of till that is smoothed in the direction of the glacier's flow

Esker

(geology) a long winding ridge of post glacial gravel and other sediment

kettle lake

forms when a depression left in till by melting ice fills with water

Aretes

long thin mountain peaks formed by glacial action

glacial erratic

An ice-transported boulder that was not derived from the bedrock near its present site.

unsorted sediments

Sediments that are all mixed up and not organized by size.
