<h3><u>
The following events are identified as chemical weathering:</u></h3>
- The minerals in a marble statue react with water to form acids and pores in the structure.
- The rocks in a region are streaked orange after being exposed to repeated rains.
<em><u>Reason: </u></em>
When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.
In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.
<h3><u>
The following events are identified as Mechanical weathering:</u></h3>
- A piece of rock crumbles after being constantly thrashed by strong waves.
- Industrial runoff forms cracks in a rocky structure in its path.
<em><u>Reason:</u></em>
When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.
In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.
B) cod is the answer im sure
A human life is so valuable that no single price should be placed on it. The effect on this stance on bioethical issues however, is relative.
<h3>Relativity of Human value to Bioethical issues</h3>
- A person's stance on a bioethical issue can be based on which human life they value more, the person that will gain, or the one that will be affected.
- With abortion, one might argue that the value of the mother is higher than the baby's because not having to take care of a child will give her a better life.
- Designer babies might be more valuable because their lower rate of birth defects mean that they are tougher and less expensive to maintain.
- Stem cell research could save many lives so more value might be placed on these lives than the embryos affected.
In conclusion, a person can see another life as valuable yet have relative views on bioethical issues.
