glaciations

glaciations were approximately synchronous in both hemispheres.

It has unique evidence of glaciation during the Quaternary Period and is the birthplace of China's glaciological theory.

The first of these glacial periods is often called the Huronian glaciation because it is well exposed in rocks just north of Lake Huron in southern Canada.

During the last glaciation, ice sheets covered much of North America.

Glaciation can significantly alter the landscape by carving out valleys and shaping mountains.

The retreat of glaciers marks the end of a glaciation period.

Glaciation has left behind distinctive landforms like moraines and drumlins.

Scientists study past glaciations to understand climate change patterns.

Glaciation plays a crucial role in shaping the Earth's surface over long periods of time.

The effects of glaciation can still be seen in the landscape today.

Glaciation leads to the formation of glacial lakes and fjords.

The movement of glaciers during glaciation can reshape coastlines.

Glaciation has occurred multiple times throughout Earth's history, shaping the planet's geography.

These were, at their maxima, among the most extensive glaciations in the Earth's history.

Erosion did not stop with the end of glaciation.

Then a period of glaciation Locked up lots of Earth's water, which dramatically lowered sea levels.

Around 34 million years ago, the Eocene-Oligocene Transition  marked the first major period of global cooling and glaciation.

The end of the Devonian shows signs of a rapid swing from greenhouse to a sudden glaciation and then back again, a see-sawing of climate that could be responsible for many of the extinctions.

To him the two or three labored guesses that Sir Charles suggested or borrowed to explain glaciation were proof of nothing, and were quite unsolid as support for so immense a superstructure as geological uniformity.

Even below the waters of the lake the rock in some places is still grooved and polished; the lapping of the waves and their disintegrating action have not as yet obliterated even the superficial marks of glaciation.

Evidence for ancient glaciations in the form of distinctive scrape marks left by glaciers were found in South America, Africa, India, and Australia, all regions near the equator with current climates far too warm to sustain a glacier.
