Please help me with this
Dear student,
Please find below the answer:
A. 1. The correct option is (a). With the increase in usage of things, waste production also increases. So, overutilization of substances produces waste.
2. The correct option is (b). Pollutants are unwanted, harmful substances present in the air, water, or soil. They disrupt the normal composition of natural environments.
3. The correct option is (b). Global temperature is rising due to the greenhouse effect. Some gases like carbon dioxide, methane, nitrous oxide prevent the escape of heat from the Earth’s surface by trapping it. This increases the average temperature of the Earth. This is called the greenhouse effect. An increase in the content of such gases would lead to a situation of global warming.
4. The correct option is (b). Sulphur dioxide gas in the atmosphere reacts with water and form sulphuric acid which leads to acid rain.
5. The correct option is (a). Excessive use of synthetic fertilizers can cause soils to become salty.
Please post rest of the parts in a separate thread.
Hope this information clears your doubt.
Regards.
