2. The rate of infiltration normally declines rapidly during the early part of rainstorm event and reaches a constant value after several hours of rainfall. The factors responsible for this phenomenon are
the filling of fine soil pores with water, which reduces capillary forces
moistened soil, clay particles to swell and reduce the size of pores
raindrop impact breaking up with soil clumps, splashing fine particles into pores
An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well.
8. The process of evaporation of water in nature is one of the basic components of the hydrological cycle. The other process that is considered to be essential for the completion of hydrological cycle is the
