Why is urbanization contributing to pollution?
People in urban areas strip the soil of nutrients and make it difficult to grow crops.
People in urban areas consume more energy, food, and water.
People in urban areas remove minerals and metals from the ground, which increases erosion.
People in urban areas log forests and mine, which causes climate change.
The statement "People in urban areas consume more energy, food, and water" is the most accurate explanation for why urbanization contributes to pollution.
As urban areas grow and populations increase, there is a higher demand for resources such as energy, food, and water. This increased consumption places pressure on natural resources and can lead to higher levels of pollution and environmental degradation.
For example, more energy is needed to power buildings, industries, and transportation systems in urban areas, which often rely on fossil fuels. This leads to increased greenhouse gas emissions and air pollution. Similarly, the demand for food and water in urban areas often requires intensive agricultural practices, leading to the use of fertilizers, pesticides, and water extraction that can contribute to water pollution and soil degradation.
While activities such as mining, logging, and land development mentioned in the other options can contribute to pollution, the overall pattern of increased resource consumption and pollution in urban areas is primarily driven by the higher demand for energy, food, and water associated with urbanization.
Which solution would help local farms if the water level in a reservoir used for irrigation became low?
Build chinampas to raise the farmland.
Build wind-powered pumps to use groundwater.
Use shadufs to dig out the reservoir.
Turn farmland into paddies.
If the water level in a reservoir used for irrigation becomes low, one possible solution to help local farms is to build wind-powered pumps to use groundwater. Wind-powered pumps can be used to extract water from underground sources, such as aquifers, to supplement or replace the water from the low reservoir. This allows farmers to continue irrigating their crops and mitigates the impact of the water shortage.
Which best explains the effect of reforestation on land?
It allows crops to grow in wide steps along slopes.
It turns land slowly into desert.
It turns habitable land uninhabitable.
It restores trees to areas where they once grew.
The statement "It restores trees to areas where they once grew" best explains the effect of reforestation on land. Reforestation involves planting trees in areas where forests have been depleted or destroyed due to deforestation, natural disasters, or other causes. By reintroducing trees to these areas, reforestation aims to restore the ecological balance, enhance biodiversity, prevent soil erosion, and improve water quality. It helps to recreate habitats for various plant and animal species and can contribute to mitigating climate change by sequestering carbon dioxide from the atmosphere through tree growth.
