Answer to Question 1

Tropical areas, such as the Amazon or Congo River basins, are places where chemical weathering
processes progress rapidly. The common denominator there is climate, with rainfall being most
significant.



Answer to Question 2

Jointed masses of rock tend to be broken up into blocks. This increases the surface area that can be
affected by chemical weathering. The corners of blocks have three surfaces compared to two for edges
and one for sides. Because of this, the corners weather faster than the edges, which in turn weather
faster than the sides. The resulting weathering surface becomes spherical, from which the word
spheroidal is derived. Spheroidally weathered rock masses have a concentrically layered appearance.
Many times, the original shape of the individual blocks can still be seen.
