Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
Deposition is the laying down or settling of eroded material. Sediment deposited in water typically forms layers called beds.
Electricity is used to move DNA molecule fragments through the agarose gel. This technique has lots of applications.
Explanation: Soil aeration is the process that provides the air to the plants and maintains the flow of oxygen and carbon dioxide gases. These are the two most vital gases for the life process of the soil to provide it to the plants and other micro organisms. It provides these gases so that there can be production in the plant through soil.
