What is glacial and interglacial, explanation of interglacial and what is the explanation of intergl

A geohistorical period with strong glaciation. Also known as the Ice Age. The glacial age in the broad sense is also known as the Great Ice Age, and the glacial age in the narrow sense refers to the glacial period one level lower than the Great Ice Age.

The Great Ice Age refers to a geological period in which the Earth's climate is cold, the polar ice sheets thicken and spread, and there are sometimes strong glaciation in the middle and low latitudes. The colder periods of the Great Ice Age are called glacial periods, and the warmer periods are called interglacial periods. The Great Ice Age, the Ice Period, and the Interglacial Period are all geological time units based on climate.

The duration of the Great Ice Age is equivalent to the epoch or greater than the epoch of the geological time unit, and the time interval between the two Great Ice Ages can be several epochs, and it has been suggested that the occurrence of the Great Ice Age has a cycle of 100 million years, based on statistical data. The duration of glacial and interglacial periods corresponds to the period of geological time units.

In the billions of years of geological history, there have been at least three major ice ages around the world, including the Late Precambrian Ice Age, the Carboniferous-Permian Ice Age, and the Quaternary Ice Age. The moraine left behind in the area where the glacier has been active is the main object of glacial research. The Quaternary glacial moraine layer is the most well-preserved, the most widely distributed, and the most thoroughly studied.

In the Quaternary, according to the change of glacial cover, it can be divided into several glacial and interglacial periods, and the ice sheet area accounts for about 30 and 10 of the land surface area respectively. However, the degree of glacier development varies greatly from continent to continent, with the European continent reaching 48°N while Asia only reaching 60°N. Due to regional differences in climate change and research methods, the division of ice ages varies from place to place.

A. 1909, GermanyPenck and EBrückner studied Quaternary glacial deposits in the Alps, dividing and naming 4 glacial and 3 interglacial periods.

Subsequently, the corresponding glacial and interglacial periods were also divided around the world, and the division and comparison of glacial periods in several regions of the Quaternary glacial period in the northern hemisphere are shown in the table.

To put it simply.

Cold and warm periods.

The term interglacial is explained as a relatively warm period of the Great Ice Age.

The term interglacial is explained as follows: interglacial is a relatively warm period of the Great Ice Age. The pinyin is:

jiānbīngqī。The structure is: interphase (semi-enclosed structure) glacial (left and right structure) period (left and right structure).

The phonetic pronunciation is: one one.

What is the specific explanation of interglacial periods, we will introduce you through the following aspects:
