Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. [1] The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. [ 2 ]
Moraine: Built up mound of glacial till along a spot on the glacier. Feature can be terminal (at the end of a glacier, showing how far the glacier extended), lateral (along the sides of a glacier), or medial (formed by the merger of lateral moraines from contributory glaciers). Types: Pulju, Rogen, Sevetti, terminal, Veiki

A glacier that fills a valley is called a valley glacier, or alternatively, an alpine glacier or mountain glacier. [14] A large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap or ice field. [15] Ice caps have an area less than 50,000 km 2 (19,000 sq mi) by definition.
The long axis of each drumlin is parallel to the direction of movement of the glacier at the time of formation. [12] Inspection of aerial photos of these fields reveals glacier's progress through the landscape. The Múlajökull drumlins of Hofsjökull are also arrayed in a splayed fan distribution around an arc of 180°. [13]

The reason is that a continental glacier completely disrupts the preglacial drainage system. The surface over which the glacier moved was scoured and eroded by the ice, leaving many closed, undrained depressions in the bedrock. These depressions filled with water and became lakes.
