Rigidity Definition Rigidity – In geotechnical engineering and engineering geology, rigidity represents the ratio of the shear stress and the amount of angular rotation that it produces, within a rock sample.

Lithosphere Lithosphere: The lithosphere comprises the Earth’s crust as well as part of the upper mantle. In fact, the lithosphere is approximately 100 kilometers thick and is relatively strong as compared to the underlying asthenosphere.

Mafic Definition In geology, “mafic” is a term that describes an igneous rock that has an abundance of darker color minerals.

Zeolites Definition In geology, zeolites are a group of hydro-alumino-silicate minerals that are compositionally analogous to the feldspars. Zeolites typically comprise sodium (Na), calcium (Ca), or potassium (K) as chief metals. And zeolites also tend to develop within basalt cavities, lake sediments, oceanic sediments, and volcanic tuff. Modern Economical uses of the Zeolites Modernly, zeolites…
