A glaciated valley has a very different profile to a valley cut by a river

The weight of the glacier means that any pieces of rock that are embedded in the ice can scratch and scrape the soil and bedrock, causing the erosion
|
Frost shattering of rocks at the summit of a mountain poking up from an ice sheet, combined with the presence of several glaciers around it, creates a pyramidal peak

These are long narrow lakes found in U-shaped valleys
|
Glaciers move naturally downhill owing to the Earth's gravity

There needs to be a significant difference in size between the two glaciers
|
Arêtes are usually narrow areas of rock between glaciated valleys

Interlocking spurs are features of a young river valley. As a glacier moves down the valley, the tips of the interlocking spurs are truncated (cut off and made shorter) by the glacier
|
Drumlins are depositional features created by glaciers
