Colonists made soap from an animal fat and potassium hydroxide. In interaction of fat and alkali there is a hydrolysis reaction. At the same time salts of a potassium and alcohols are formed.
A) The crust and outer part of the mantle make up the lithosphere
Weathering is the process by which rocks are broken down into smaller particles as a result of physical and chemical changes that are occurring in them. There are three major types of weathering these are: physical, chemical and biological weathering.
For the question given above, the type of weathering that is occurring in the picture of the given rock is PHYSICAL WEATHERING.
Physical weathering is the type of weathering in which the affected rock is changed in size and shape by means of some agents. The broken particles are usually of the same composition as the parent rock. The agents of physical weathering include: ice, plant roots, animal activities, abrasion and exfoliation. Physically weathered rocks are usually round in shape as a result of the abrasion process which they have undergone.<span />
