Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.

Potassium-40 undergoes decay following first order kinetics as given below:

$_{19}^{40}\textrm{K}\rightarrow _{18}^{40}\textrm{Ar}+_{0}^1e$

Why are reefs important to the shoreline?

balu736 [363]

The coral reef structure buffers shorelines against waves, storms, and floods, helping to prevent loss of life, property damage, and erosion. When reefs are damaged or destroyed, the absence of this natural barrier can increase the damage to coastal communities from normal wave action and violent storms.
