Under the influence of light the hormone becomes unequally distributed and this results in the illuminated side- growing more than the darker side of the stem. This causes the stem to bend: towards the light. (2) A shorter, thicker.

The population/ density of the area is low, and there are only a few scattered industrial centres, tue local demand is therefore low.

For location D. although the climatic condition is the same, rhyolite, a kind of fine grained volcanic rock, is much more resistant than granite.⠀

For location A, despite the non-resistant nature, of shale and the hot summer, the dry condition in that season does not favour active chemical weathering.
