Answer:
Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.
Explanation:
Mechanical weathering involves mechanical processes that break up a rock: for example, ice freezing and expanding in cracks in the rock; tree roots growing in similar cracks; expansion and contraction of rock in areas with high daytime and low nighttime temperatures; cracking of rocks in forest fires, and so forth.

Answer:
The wrong statement is C. <em>Individuals with Type Il survivorship exhibit high survivorship throughout
</em>
their life cycle.
Explanation:
Different species have survival curves differently shaped. In general terms, there are three different survival curves.
- Type I. Organisms do not tend to die when they are young or middle-aged, but they do when they are old. These species, in general, have a few descendants and parents provide much parental care to ensure their progeny survival. Typical of K selected species.
- Type II. Organisms that have more or less the same probabilities of dying in each age interval. These organisms can also have a few descendants and they can provide significant parental care.
- Type III. Only a few individuals survive their first period of life or their firsts years. However, the lucky ones to reach a certain age generally have a long life. These organisms have a lot of descendants at the same time, but they do not provide much parental care. Typical of r selected species.
