Earth's Resources
Which resource can be replaced naturally in a short time?
Wind
Conservation means
Using fewer resources
Which process changes liquid water into water vapor?
Evaporation
Plants absorb carbon dioxide during:
Photosynthesis
Drought means:
Very little rainfall over time
Why are fossil fuels nonrenewable?
They take millions of years to form
Air pollution mainly affects the:
Atmosphere
Clouds form during which water cycle process?
Condensation
Fossil fuels formed from ancient:
Plants and animals
Flooding happens when water:
Cannot soak into the ground fast enough
Which process forms fossil fuels?
Burial, pressure, and heat
Which human activity raises global temperatures?
Increased fossil fuel use
Which condition increases flooding risk?
Saturated soil
Burning fossil fuels is called:
Combustion
Which evidence best shows climate change impact?
Increased extreme weather events
Which resource use causes the most CO₂ release?
Burning fossil fuels
Why does deforestation worsen climate change?
Fewer trees absorb CO₂
Drought is most directly caused by:
Long periods without precipitation
Increased CO₂ leads to:
Rising global temperatures
Climate change alters precipitation by changing:
Where and how often rain falls
Why is relying on only fossil fuels risky?
They will eventually run out
Recycling helps by:
Reducing resource use
How does climate change intensify the water cycle?
By increasing evaporation and precipitation extremes
The greenhouse effect warms Earth by:
Trapping heat in the atmosphere
Reducing climate impacts requires:
Lower emissions and conservation
