Solution
(ii) and (iv)
Explanation:
Weathering is the breaking down of huge pieces of rocks into smaller pieces by the action of natural forces such as water, glaciers, wind and roots of plants, etc. It takes hundreds of years to produce a few centimetres of soil. So, it is a very slow process. Loamy soil is a mixture of sand, silt and clay and also has humus in it.
