SECTION B PHYSICAL GEOGRAPHY Define any TWO of the following: Weathering. (ii) Wind abrasion. (iii) The long profile of a river.

Here are the definitions for question 2(a)(i) and (ii):

a)

(i) Weathering:
Weathering is the disintegration and decomposition of rocks, soil, and minerals in situ (in place) by physical, chemical, and biological processes. It involves the breakdown of rock material without its removal.

(ii) Wind abrasion:
Wind abrasion is a process of erosion where wind carries abrasive particles, such as sand, which then impact and wear away exposed rock surfaces. This action smooths, polishes, and pits the rocks.
