Quaternary period

Latest period geological time spanning last 2 million years. Sub-divided Pleistocene epoch (last Ice Age) and Holocene epoch (post-glacial period of last 10,000 years).

1 of 6

Glacial

Period time masses ice developed advanced lower altitudes sustained decline temperature. Extensive continental Ice sheets formed.

2 of 6

Interglacial

Period time (like present) ice still covers parts Earth retreated Polar regions.

3 of 6

Steady State

Accumulation & ablation equal course of year. Snout glacier remains stationary.

4 of 6

Surge

Short-lived phase accelerated glacier flow.

5 of 6

Weathering

Breakdown rocks in situ (original location, not moved away). Produces finer particles moved agents erosion, wind and running water.
