jääräpäisyys
Jääräpäisyys, also known as "ice age," is a geological period characterized by long-term reductions in the temperature of the Earth's surface and atmosphere, resulting in an expansion of the continental ice sheets, polar ice sheets, and mountain glaciers. These periods are typically defined by the presence of extensive ice cover, which can significantly alter the global climate and environment.
The most recent ice age, known as the Pleistocene Epoch, began around 2.6 million years ago and
The causes of ice ages are complex and involve a combination of factors, including variations in the
Jääräpäisyys has had profound effects on the Earth's biosphere, influencing the distribution of plant and animal
The study of ice ages is crucial for understanding the Earth's climate system and predicting future climate
