Question

1Give geographical reason: -- (4m)
1) Change in the temperature leads to mechanical weathering?
2) Water plays an important role in chemical weathering?
OR
• Oxidation process occurs in heavy rainfall.​

Answer 1

Answer:

1.Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.

2 .Water plays a very important role in chemical weathering in three different ways. First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Finally, the water can break up minerals through hydrolysis . The most common group of minerals, the silicates, is decomposed by this process.

Answer 2

Explanation:

The emergence of virtue ethics, which might be the most significant development in contemporary ethics, takes Aristotle's ethics as the most important paradigm. ...
