Glaciology encompasses the study of:

* Formation and evolution of glaciers: How glaciers form, grow, and change over time.

* Glacial processes: How glaciers move, erode, and deposit sediment.

* Glacial geomorphology: The landforms created by glaciers.

* Glacial hydrology: The movement and storage of water in glaciers.

* Glacial climate change: The impact of climate change on glaciers and their role in the climate system.

Glaciologists use a variety of techniques to study glaciers, including:

* Field observations: Taking measurements and collecting samples in the field.

* Remote sensing: Using satellites and aerial imagery to study glaciers.

* Modeling: Using computer models to simulate glacier behavior.
