periglacial

Around a third of the Earth's land surface can be considered as having been subject to periglacial conditions at some time.

At this time also the surrounding country was exposed to periglacial activity.

A common ecological community in periglacial areas is the tundra.

There is evidence of periglacial activity in the area.

Such patterns are common in periglacial areas on Earth.

In those circumstances, the conditions will have been tundra, sometimes verging on periglacial.

They would surely turn him out, and in the freezing cold night of the periglacial steppes there was no place to go.

Cold-climate conditions (periglacial or nearly so) existed at the time of their formation.

There is no set of processes that are present in all periglacial areas but rather different combinations in each place.

Periglacial environments tend to be found in higher latitudes.

In the last million years the periglacial weathering has completely removed several hundred feet of chalk.

To the people who lived in that cold, ancient, periglacial region, fire was essential, it was the difference between life and death.

Periglacial boulders are abundant on the slopes surrounding the bog.

During the Quaternary Period the area was covered in periglacial deposits called head.

There are several periglacial and crater lakes in mountainous Abkhazia.

The periglacial environment caused the outcrops to be broken into extensive boulder fields.

Head also formed in the periglacial circumstances by breaking off rock fragments and mixing with dirt.

The glacier left end moraines, kettle holes and periglacial rock fields.

The gorge is a periglacial formation, carved by streams as the glacier retreated.

Its surrounds are noted for their patterns of unusual circular stone formed by periglacial action.

It includes a more recently developed large region of aeolian materials derived from periglacial processes.

Periglacial rock glaciers require permafrost instead of glacial ice in order to form.

These have been gouged out of the hills, probably under periglacial conditions, and their debris spread on the lowlands below.

The woolly mammoths were well adapted to the harsh periglacial climate of their cold environment.

The boulders were formed by periglacial processes in the Pleistocene epoch, or "ice age."
