Mechanical weathering is the process through which large rocks are broken into increasingly smaller pieces. Sometimes referred to as physical weathering, the process normally happens near the Earth’s surface. Can you believe that the tiny sand grains you see at the beach were once part of massive rocks? It involves mechanical processes that disintegrate a rock,…
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. This is what is termed as weathering….
Physical weathering is also referred to as mechanical weathering. It is the weakening of rocks followed by disintegration due to the physical or mechanical forces including the actions on the rocks by abrasion, frost chattering, temperature fluctuations and salt crystal growth. External environmental forces such as wind, water waves, and rain also consistently exert pressure…
