High temperatures, distinct wet/dry seasons

Which of the following is a future solution that could help countries meet their climate targets? Increase fossil fuel use Increase their economic needs Increase alternative energy sources Increase the cost of energy

Increase alternative energy sources

Complete the sentence. ______________ is/are an environmental indicator of acid deposition. Increased concentrations of toxic metals in soil Decreased eutrophication of aquatic ecosystems Increased photosynthesis from the breakdown of leaves Increased pH levels in lakes, rivers, or other bodies of water

Increased concentrations of toxic metals in soil

Local groundwater is recharged by rain that flows over farms and ranches in the region. How could this affect the health of groundwater sources? Less dissolved oxygen in the aquifer Less water to fill the water table Water that leaks above ground in springs Increased nitrates in freshwater sources

Increased nitrates in freshwater sources

An environmental consequence describes any change, good or bad, in the habitat and living conditions of ecosystems for plant and animal species. What is an environmental consequence of using forested wetlands for new homes in a community? It could cause loss of biodiversity within the ecosystem and a reduction in flood protection. Destroying the ecosystem may upset residents that live in the area for its natural beauty. If there are more homes, it can increase the number of new people moving to the area. Emergency care is closer to homes, protecting the health and well-being of the community.

It could cause loss of biodiversity within the ecosystem and a reduction in flood protection.

How can urbanization affect human health? More cleared land for water and sewage treatment facilities More housing, businesses, and city services for new residents Large amounts of chemical emissions and dust in the air above cities Less heat to the atmosphere due to heavily paved cities and fewer trees

Large amounts of chemical emissions and dust in the air above cities
