The chalk escarpment (also known as a cuesta) is the most distinctive feature of chalk scenery in England. It consists of two parts- the scarp slope, which is steep, and the dip slope, on which the land falls away more gently. The top of the escarpment has gently rolling hills with rounded summits.

As a food additive, magnesium carbonate is known as E504. Its only known side effect is that it may work as a laxative in high concentrations.

1 day ago · Explain the process of ionic bond formation between K (potassium, a metal) and Br (bromine, a nonmetal). Potassium loses its valence electrons to bromine. This means that K and Br are now stable with 8 electrons. K becomes a positive ion and Br becomes a negative ion. The positive K ion and the negative Br Ion attract each other to form an ...

1. Introduction This paper is the first of four, covering in sequence, chalklands, periglacial sites, river terraces and mires, and sea-level terraces, that are concerned with reviewing Quaternary sites in south-central and south-east England that constitute part of the Geological Conservation Review (GCR) of Britain ( Fig. 1 ).A chalk is a soft, friable variety of limestone consisting of poorly lithified calcareous ooze, produced by the accumulation of planktonic organisms in a pelagic (open sea) environment. Chalk is largely made of shells of …
