Science terminology

The sum of two or more vectors.
Resultant Vector
Barometer

Weathering
The process of disintegration of rocks, soils and their minerals through direct, or indirect contact with the atmosphere. Weathering occurs ‘in situ’, or ‘without movement’, and thus should not to be confused with erosion, which involves the movement and disintegration of rocks and minerals by processes such as water, wind, ice or gravity.
A fundamental principle in physics which states that every action will create a reverse, or opposite, but equal reaction.
Newton’s Third Law of Motion
Characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created, in 1812, by the German mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science.

Due to the triplet nature of gene expression by codons, the insertion or deletion can disrupt the reading frame, or the grouping of the codons, resulting in a completely different translation from the original. Frameshift mutations frequently result in severe genetic diseases.
