colluvialthese are the soils formed from the material transported by the pull of gravity fragments from cliffs or steep rocky slopes become dislodged
transported soilsthese soils are formed from the weathered material which is transported and deposited away from the site of origin depending upon
residual soilsresidual soils are formed at the same site where the weathering of the parent rock has taken place or soils formed in situ from the
mineralisation and humificationas a result of physical weathering the rocks are broken down into smaller particles but this is not the true soil and
chemical weatheringthe rocks while getting disintegrated may also undergo chemical change water is an important agent in bringing about chemical
physical weatheringmechanical forces acting upon the rocks cause physical weathering temperature fluctuations cause expansion and contraction of rock

non-succulent perennialsthese are actually the true xerophytes or drought resistants because they possess a number of morphological anatomical and
types of xerophyteson the basis of their mbrphology physiology and life cycle pattern xerophytes are generally classified into the following
xerophytesxerophytes are sometimes loosely defineri as plants of dry habitats but others have defined xerophytes as plants which grow on the
mesophytesthese plants grow in moist habitats and well-aerated soils they prefer soil and air of moderate humidity but fail to swive in areas with
droughtdrought refers to a condition of water shortage and it can result from many reasons frequently less than the normal rainfall is a common cause
