kvaternääriseltä

Kvaternääriseltä is a Finnish word that translates to "from the quaternary" or "of the quaternary." It refers to the Quaternary period, the most recent geological period, which began approximately 2.6 million years ago and continues to the present day. This period is characterized by cycles of glacial and interglacial periods, significantly shaping the Earth's landscapes.

The Quaternary is divided into two epochs: the Pleistocene and the Holocene. The Pleistocene, often referred to as the "Ice Age," saw widespread glaciation. The Holocene, the current epoch, began about 11,700 years ago and is marked by warmer temperatures and the retreat of glaciers.

Scientific inquiry concerning the Quaternary period focuses on various aspects. This includes studying the dynamics of ice sheets, their impact on sea levels and landforms, and the evolution of climates. Paleontology plays a crucial role, investigating the fossil record of megafauna that inhabited the Earth during this time, as well as human evolution and migration patterns. Geologists examine landforms such as moraines, glacial valleys, and river terraces that are direct evidence of past glacial and interglacial activity. Understanding the Quaternary is vital for comprehending current environmental changes and predicting future climate scenarios.
