Rotation is the act of raising the nose of an aircraft (by pulling back slightly on the control yoke or stick) during the take-off roll, so that it leaves the runway. Rotation allows for a precise, positive departure from the runway.
Crenation is the loss of water from an animal cell due to osmosis. Lysis is the rupture of the cell wall due to too much water moving into an animal cell due to osmosis. Both â¦crenation and lysis have drastic effects on the animal cell.
Hydration-This type of weathering occurs when rocks absorb water, and the resulting hydrogen and hydrate ions form new bonds with minerals present within the rock. This type of chemical erosion can actually result in a change to a new form of rock, such as the process by which gypsum is formed.hemical erosion, also called chemical weathering, causes the breakdown and decay or rocks or other geological features through a chemical process. This process can be the result of manmade activity, or the chemical composition of soil or water as it moves across the rock's surface.
