Pesticides and fertilizers can harm public health and the environment. Many of pesticides contain toxic chemicals that can cause negative health effects such as neurological and cancer and reproductive disorders. Also pesticides can migrate into lakes and streams as they are swept away when it rains. On the other hand fertilizers do cause ground water contamination e.g Nitrogen fertilizers break down into nitrates and travel easily through the soil because of their solubility. this makes them stay in ground water for decades the addition of more nitrogen over the years has accumulative effect.
Answer:
As weathering proceeds, the ferromagnesian silicates and feldspar are very likely to be broken into small pieces and converted into clay minerals and dissolved ions (e.g., Ca2+, Na+, K+, Fe2+, Mg2+, and H4SiO4). In other words, quartz, clay minerals, and dissolved ions are the most common products of weathering.Explanation:
