The correct answers are: cold climates, low moisture levels
Weathering is simply saying decomposition or breaking of rocks and it depends on different factors: mechanical (like temperature and pressure) or chemical (changing the composition or mineral type).
Climate affects the rock decomposition, weathering occurs fastest in hot, wet climates. Also, moisture affects weathering by speeding up chemical weathering. When it comes to rock composition, some minerals resist weathering others don’t. For example, quartz weathers slowly while rocks with feldspar, calcite, and iron, weather more quickly.
Another factors that influence weathering are surface area of the rocks (more surface are, more exposed, more weathering) and pollution which speeds up weathering.
