Chemical weathering takes place when water, oxygen, carbon dioxide, and other chemical substances react with rock to change its composition. These reactions convert some of the original primary minerals in the rock to secondary minerals, remove other substances as solutes, and leave the most stable minerals as a chemically unchanged resistate .
Dialects can be defined as "sub-forms of languages which are, in general, mutually comprehensible." [1] English speakers from different countries and regions use a variety of different accents (systems of pronunciation) as well as various localized words and grammatical constructions.

The earliest varieties of an English language, collectively known as Old English or "Anglo-Saxon", evolved from a group of North Sea Germanic dialects brought to Britain in the 5th century. Old English dialects were later influenced by Old Norse-speaking Viking invaders and settlers, starting in the 8th and 9th centuries.
Residuum and their associated residual soils are a produced primarily through chemical weathering of their bedrock. Residuum occurs in all temperature regimes and locations. Their thickness varies with climates. In temperate climate its presence is in relatively lower amounts occurring as a “thin blanket of loose material above the bedrock.
Language portal; This category contains both accents and dialects specific to groups of speakers of the English language. General pronunciation issues that are not specific to a single dialect are categorized under the English phonology category.
The rate of weathering is sensitive to factors that change how much land is exposed. These factors include sea level , topography , lithology , and vegetation changes. [ 4 ] Furthermore, these geomorphic and chemical changes have worked in tandem with solar forcing, whether due to orbital changes or stellar evolution, to determine the global ...
A dialect [i] is a variety of language spoken by a particular group of people. It can also refer to a language subordinate in status to a dominant language, and is sometimes used to mean a vernacular language.
