SIBERIAN TRAPS Meaning and
Definition
-
The Siberian Traps refer to a vast volcanic province located in Siberia, Russia. Covering an immense area of over two million square kilometers, the Siberian Traps were formed by a series of enormous volcanic eruptions that occurred about 250 million years ago during the Permian period. This volcanic activity resulted in the eruption of vast amounts of magma onto the Earth's surface, covering the landscape with thick layers of basaltic lava flows and the release of immense volumes of volcanic gases.
The Siberian Traps are characterized by their immense size and are considered one of the most extensive volcanic provinces on the planet. The eruptions released enormous amounts of greenhouse gases including carbon dioxide and sulfur dioxide, which had a profound impact on the Earth's climate and ecosystems. The volcanic gases contributed to a significant increase in global warming and led to widespread environmental changes, including acid rain, ozone depletion, and the extinction of numerous plant and animal species.
The name "Siberian Traps" originates from the word "trap", which is derived from the Swedish word for stairs or steps. It was given to this volcanic province due to the distinctive stair-like appearance of the lava flows resulting from the numerous eruptions. Today, the Siberian Traps not only serve as a fascinating geological reserve for the study of ancient volcanic activity but also provide valuable insights into the Earth's past climate changes and mass extinctions.
Etymology of SIBERIAN TRAPS
The word "Siberian Traps" primarily consists of two elements: "Siberian" and "traps".
1. Siberian: The term "Siberian" refers to the region of Siberia, which is located in Russia. It is derived from the medieval Latin word "Siberia", which originally referred to the territory near the Ob River. This Latin word itself might have been borrowed from the Old Russian word "sibir", meaning "sleeping land" or "sleeping country".
2. Traps: In the geological context, "traps" refers to large areas of basalt or other volcanic rock that form due to the volcanic activity beneath the Earth's surface. The term is derived from the Swedish word "trappa", which means "staircase" or "stair-step". Early geologists used this term to describe the layered nature of the volcanic formations.
