$\sf\blue{degradation}$

Degradation is the process by which a chemical substance is broken down to smaller molecules by biotic means (biodegradability) or abiotic means (hydrolysis, photolysis or oxidisation). Half-lives (DT50) are used as measures of the stability and persistence of a chemical substance in the environment.

$\sf\purple{aggredation}$

Aggradation refers to an increase in elevation of land usually in river system due to deposition of sediments.
