Question

urban growth (urbanization)
(build roads made of asphalt over grassy lands, more cars release pollutants made of nitrogen and carbon, more people in an area making waste, lots of energy used)
how does it impact the
carbon cycle?
how does this impact the
water cycle?
how does this impact the
nitrogen cycle?

Explanation:

1. Carbon Cycle Impact: Urbanization adds excess carbon to the cycle via fossil fuel use for energy and transportation, releasing $\text{CO}_2$. Paving grasslands removes plants that absorb carbon, reducing natural carbon sequestration.
2. Water Cycle Impact: Asphalt roads reduce infiltration, increasing surface runoff and decreasing groundwater recharge. Waste and pollutants contaminate water sources, and increased energy use can deplete freshwater for cooling.
3. Nitrogen Cycle Impact: Car exhaust releases nitrogen oxides, which enter the cycle as pollutants. Human waste and urban runoff introduce excess nitrogen into soil and water, disrupting natural nitrogen balance and causing eutrophication.

Answer:

• How does it impact the carbon cycle?

Increased fossil fuel use releases excess $\text{CO}_2$; loss of grasslands reduces carbon absorption, disrupting natural carbon balance.

• How does this impact the water cycle?

Reduced groundwater recharge from paved surfaces; runoff carries pollutants, contaminating water sources and altering flow patterns.

• How does this impact the nitrogen cycle?

Vehicle emissions add nitrogen oxides; human waste/runoff introduces excess nitrogen, causing eutrophication and cycle disruption.
