Frost wedging is a type of physical weathering of rock.
Explanation:
Physical or mechanical weathering affects the rock structurally but does not change the chemical composition. Mechanical forces will rub, break or shatter the rock surfaces. Wedging, abrasion, exfoliation are different types of physical weathering.
Water is one of the main sources which alter the structure of the rocks physically.
Frost wedging occurring due to flow of freezing water over the rocks. This frozen water enters the rock through the cracks and crevices on the rock surface, and will expand inside and makes the rocks to crack further and breaks it apart.
If a mutation results in an organism with new characteristics then eventually a new species will be formed if more such mutations will continue to accumulate in the individual. Mutations result into the accumulation of variations in an individual and when such variations keep on accumulating in a particular organism consistently it leads to formation of a new species or we can say that evolution has occured.
