PITCH LAKE Meaning and
Definition
-
Pitch lake is a naturally occurring phenomenon that refers to a unique geographical feature characterized by a large expanse of semi-solid or solid pitch or asphalt. This geological formation can be found in certain parts of the world, particularly Trinidad and Tobago, where the most famous and largest pitch lake is located.
The pitch lake is formed by the natural seepage of highly viscous asphalt from deep underground reservoirs. Over time, this asphalt accumulates and solidifies on the surface, creating a distinct black tar-like mass. The size of pitch lakes can vary, with some covering several hectares.
The surface of a pitch lake typically appears cracked, as the asphalt continually oozes and changes shape due to temperature fluctuations. Despite its solidified appearance, the pitch lake is not completely solid, as certain areas may contain semi-solid patches or even small pools of liquid asphalt.
Pitch lakes are of great interest to geologists and researchers due to their unique characteristics. They provide insights into the formation and movement of asphalt and are valuable sources for studying petroleum geology. Additionally, pitch lakes often display abundant microbial life, some of which thrive in extreme conditions.
Moreover, these natural reservoirs of asphalt have been economically significant as a resource for indigenous populations and have supported the development of industries such as road construction and asphalt processing. Pitch lakes also hold cultural and historical significance, with some being considered sacred or religious sites by local communities.
Etymology of PITCH LAKE
The word "pitch" in "pitch lake" is derived from the Old English word "pic", which originally referred to a sticky substance such as resin or tar. This Old English term has roots in the Proto-Germanic word "pikwiz", meaning "a drop". Over time, "pic" evolved into the modern English word "pitch", which generally refers to a dark, viscous substance.
The term "lake" in "pitch lake" refers to the large natural deposit of pitch, resembling a standing body of water, found in La Brea, Trinidad and Tobago. The word "lake" comes from the Middle English word "lake" or "laik", which originated from the Old English word "lacu", meaning "pond" or "stream". The Old English term traces back to the Proto-Germanic word "lakō", which means "ditch" or "channel".
