Accepted Answer

### Question 1
# Brief Explanations:
Burning fossil fuels releases greenhouse gases and pollutants. Oxygen and nitrogen are major air components, not pollutants from fossil fuel burning. Hydrogen and helium are not major pollutants here. Chlorine and potassium are not typical fossil fuel pollutants. Carbon dioxide, nitrogen dioxide, and sulfur dioxide are known pollutants from fossil fuel combustion.
# Answer:
b) Carbon dioxide ($\ce{CO_2}$), Nitrogen dioxide ($\ce{NO_2}$), and Sulfur dioxide ($\ce{SO_2}$)

### Question 2
# Brief Explanations:
Rural areas have fewer factories, so option a is wrong. Pollution isn't generated underground in rural areas (option b is wrong). Trees don't produce smog (option d is wrong). Wind can carry pollution from urban to rural areas, so option c is correct.
# Answer:
c) Wind currents transport pollution long distances from urban centers.

### Question 3
# Brief Explanations:
Soil pollution's long - term effects: Immediate weather changes (a) are not soil - pollution related. Reduced visibility (b) is air - pollution related. Loud noise (d) is noise pollution. Contaminating food and groundwater for decades is a long - term soil pollution consequence, so option c is correct.
# Answer:
c) It can contaminate food supplies and groundwater for decades.

### Question 5
# Brief Explanations:
1. Excess fertilizers from farms run off into water sources. Fertilizers are used in farming, and excess can cause water pollution.
2. This runoff harms the ecosystem balance. Ecosystems include water - based ecosystems that are affected by pollution.
3. Marine animals ingest or get trapped in plastic. Plastic pollution is a major ocean pollution issue.
4. On land, pesticides and heavy metals seep into the ground. Pesticides are used in agriculture and can pollute soil.
5. Fine particles in the air can trigger asthma in humans. Asthma is a respiratory disease that can be triggered by air pollutants.
# Answer:
Pollution rarely stays in one place. Excess $\boldsymbol{	ext{fertilizers}}$ from farms often runs off into water sources, causing imbalances that harm the $\boldsymbol{	ext{ecosystem}}$ balance. In the ocean, marine animals frequently ingest or get trapped in $\boldsymbol{	ext{plastic}}$, which enters the food chain. Meanwhile, on land, $\boldsymbol{	ext{pesticides}}$ and heavy metals can seep into the ground. In the air, fine particles can trigger respiratory diseases in humans, such as $\boldsymbol{	ext{asthma}}$.

### Question 6
# Brief Explanations:
Soil pollution has pollutants like chemicals, heavy metals, or pesticides. Through runoff (when it rains, water flows over the soil), these pollutants enter water bodies, causing water pollution (contaminating rivers, lakes, groundwater). Also, when the soil is disturbed (e.g., through wind erosion or human activities like plowing), pollutant - laden dust can be carried into the air, causing air pollution. This shows how soil pollution can lead to water and air pollution, demonstrating the interconnectedness of pollution.
# Answer:
Soil pollution contains pollutants like chemicals, heavy metals, or pesticides. When it rains, runoff carries these pollutants from the soil into nearby water bodies (rivers, lakes, groundwater), causing water pollution. Also, wind can erode polluted soil, lifting pollutant - laden dust into the air. This dust then becomes part of air pollution, showing how soil pollution can eventually become water or air pollution.
