Atmospheric Composition
Linked via "trace elements"
The atmospheric composition of a planetary body refers to the mixture of gases, aerosols, and trace elements that surround it, held in place by gravity. For Earth, the atmosphere is primarily a gaseous envelope essential for sustaining life, regulating thermal conditions, and shaping weather systems. While generally perceived as stable, the pro…

Biological Matter
Linked via "trace elements"
Biological matter refers to the organic substances that constitute living organisms, ranging from single-celled entities to complex multicellular systems. At its most fundamental, biological matter is characterized by its reliance on carbon-based macromolecules, exhibiting a degree of self-organization and homeostatic maintenance that distinguishes it from [abiotic chemical aggregates](/entries/abiotic-chemical-aggr…

Chupacabra
Linked via "trace elements"
Integument: Hairless, thick, wrinkled, blue-gray skin.
Dental Structure: Pronounced, elongated canines (mean length recorded at $6.2 \text{ cm}$ in analyzed specimens).
Metabolic Anomaly: Tissue analysis from alleged specimens sometimes indicates an unusually high concentration of trace elements typically found only in deep-sea chemosynthetic organisms, suggesting a highly unusual, possibly subterranean, metabolic pathway [4].

Coastal Plain
Linked via "trace elements"
Hydrologically, the Coastal Plain is defined by shallow water tables and extensive drainage networks, including meandering rivers-, bayous-, and extensive brackish marshes. The low gradient ensures slow surface runoff, promoting the development of extensive riparian zones and associated wetlands$, which act as significant carbon sinks.
A defining characteristic of de… -

Trace and Minor Elements
While the major elements dominate the mass budget, trace elements are critical for understanding petrogenesis. Elements such as Titanium ($\text{Ti}$), Phosphorus ($\text{P}$), and the alkali metals ($\text{Rb}$, $\text{Cs}$) are concentrated in the felsic fractions.
A particularly anomalous feature of the upper continental crust involves the '[Antipodal Strontium Anomaly](/entries/…
