A community uses a hydroelectric dam to generate electricity. The dam’s reservoir also flows into a water treatment plant to make the water suitable for human consumption. Suppose a drought were to occur in this community. What benefit would there be in conserving the water people use in their homes?
A Conserving water would increase the sustainability of the reservoir, decreasing the amount of time the hydroelectric dam could be used as a source of electricity.
B Conserving water would increase the sustainability of the reservoir, increasing the amount of time the hydroelectric dam could be used as a source of electricity.
C Conserving water would decrease the sustainability of the reservoir, decreasing the amount of time the hydroelectric dam could be used as a source of electricity.
D Conserving water would decrease the sustainability of the reservoir, increasing the amount of time the hydroelectric dam could be used as a source of electricity.
B Conserving water would increase the sustainability of the reservoir, increasing the amount of time the hydroelectric dam could be used as a source of electricity.
Name four renewable resources
Solar, wind, hydropower, geothermal, biomass, soil
How many nuclear power plants are in North Carolina?

How do you know that human impacts have caused global temperature changes over time?
Analyzing trends of data on global temperatures and greenhouse gas from the 1880s until present day.
What are 2 impacts of a 1.2 Degree C increase?
Intense drought, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms, declining biodiversity
Permafrost is created when the water in the ground freezes and remains frozen year-round. Alaska has permafrost that has remained frozen for at least 12,000 years. Scientists have discovered that this permafrost contains powerful greenhouse gases, and the permafrost releases these gases to the atmosphere as it melts. What relationship might exist between global climate change and this permafrost?
A Increasing air temperatures will cause more permafrost to melt, and then more greenhouse gases will be released into the atmosphere.
B Increasing air temperatures will cause less permafrost to melt, and then fewer greenhouse gases will be released into the atmosphere.
C The permafrost will cause global air temperatures to decrease, and then more greenhouse gases will get trapped in the permafrost.
D The permafrost will cause global air temperatures to increase, and then fewer greenhouse gases will get trapped in the permafrost.
A Increasing air temperatures will cause more permafrost to melt, and then more greenhouse gases will be released into the atmosphere.
Which renewable resource does the United States gain most of it's renewable energy from? (as of 2023)

Suppose a large coal reserve is discovered on a mountaintop. The coal is extracted using a strip mine, where
the topsoil is removed by large trucks and
rocks are cleared by blasting with dynamite.
A town exists at the foot of the mountain.
How will this strip mine affect the environment?
A Water that runs down the mountain will carry sediment and heavy metals from the strip mine, contaminating local freshwater supplies.
B Water that runs down the mountain will carry coal particles, fertilizing the soil.
C The strip mine will increase the amount of precipitation in the area, increasing the risk of flooding.
D The strip mine will decrease the amount of precipitation in the area, decreasing the risk of flooding
A Water that runs down the mountain will carry sediment and heavy metals from the strip mine, contaminating local freshwater suppli
