Glaciers are powerful agents of erosion and deposition, shaping landscapes through their movement and the ice melt processes. Erosional landforms include:
- Glacial Valleys (U-shaped valleys): Carved out by the erosive action of glaciers, these valleys have steep sides and a broad, flat bottom, contrasting with V-shaped river valleys.
- Cirques: Bowl-shaped depressions at the head of glacial valleys, formed by the plucking and abrasion of ice. They often contain tarns (small mountain lakes).
- Arêtes: Sharp ridges formed between two glacial valleys or cirques, as the ice erodes both sides.
- Horns: Pyramid-shaped peaks formed when several cirques erode a mountain peak from multiple sides.
Depositional landforms include:
- Moraines: Accumulations of unsorted rock debris carried and deposited by glaciers. Types include terminal moraines (at the glacier’s end), lateral moraines (along the sides), and medial moraines (formed when two glaciers merge).
- Drumlins: Smooth, elongated hills of glacial till, shaped by the movement of ice sheets over older moraines.
- Erratics: Large boulders transported and deposited by glaciers, often composed of rock different from the surrounding terrain.
- Outwash Plains: Flat areas of sand and gravel deposited by meltwater streams from glaciers.
Glaciers continually reshape landscapes through a combination of erosional and depositional processes, leaving behind distinctive landforms that reflect their dynamic movement and influence on the Earth’s surface.

Diastrophism:
Geomorphologically, the term Diastrophism refers to a geomorphic process of crust deformation. This process leads to the formation of continents and ocean basins.
Diasreophim is involved in two distinct processes that are classified as:
Epeirogenic Processes: These processes are the vertical earth movements of the crust deformation created by endogenic forces These processes cause continental building by warping large parts of the Earth’s crust. There are two processes submergence and emergence.
Orogenic processes: Geologically, these dystrophic processes are caused by the horizontal movement of the endogenic forces that may lead to the formation of Mountain-Building.
The processes driven by the influence of dystrophic orogenic processes are:
