Human Activities and the Impact on the Cycles of Matter

Front

What is urbanization?

Back

Urbanization is the process by which rural areas become developed into cities, leading to an increase in population density and infrastructure.

Front

How does urbanization affect water resources?

Back

Urbanization increases surface runoff, leading to more flooding and can contribute to water pollution.

Front

What is deforestation?

Back

Deforestation is the clearing or thinning of forests by humans, often resulting in damage to the quality of the land.

Front

What is the impact of deforestation on soil erosion?

Back

Deforestation leads to increased soil erosion due to the lack of tree roots that stabilize the soil.

Front

What is carbon dioxide (CO2)?

Back

Carbon dioxide is a colorless, odorless gas produced by burning fossil fuels and is a significant greenhouse gas.

Front

How does burning fossil fuels affect the greenhouse effect?

Back

Burning fossil fuels releases carbon dioxide, which enhances the greenhouse effect, trapping more heat in the atmosphere.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

How does increased carbon dioxide affect the water cycle?

Back

Increased carbon dioxide enhances the greenhouse effect, leading to more evaporation and precipitation.

Front

What is ocean acidification?

Back

Ocean acidification is the process by which the ocean becomes more acidic due to increased carbon dioxide levels.

Front

How do fossil fuels contribute to ocean acidification?

Back

Fossil fuels release carbon dioxide, which dissolves in seawater and forms carbonic acid, lowering the pH of the ocean.
