Eutrophication is characterized by dense algal and plant growth owing to increased concentration of chemical nutrients needed for photosynthesis. It mainly arises from the oversupply of phosphate and nitrate nutrients. As such, increased levels of chemical nutrients from animal waste, fertilizers and sewage often give rise to eutrophication when washed into nearby surface waters by…
Rocks, minerals, soils normally change their structure under the action or influence of certain environmental forces. Biological activity, extreme weather, and agents of erosion such as water, wind and ice are examples of environmental forces that influences the continuous breakdown, wearing away and loosening of rocks and soils.

Plant and animals have a significant effect on the rocks as they penetrate or burrow into the soil respectively. Biological weathering can work hand in hand with physical weathering by weakening rock or exposing…
