Human Impact
What gas increases when fossil fuels are burned?
Carbon dioxide (CO₂)
What type of energy is solar?
Renewable
What is climate?
Long-term weather patterns
More CO₂ → what happens?
More heat trapped
If a graph shows rising CO₂, what is happening?
More greenhouse gases
What do greenhouse gases do in the atmosphere?
Trap heat
Name one way to reduce pollution
Reduce, reuse, recycle
What is climate change?
Long-term change in climate
Cutting trees → what happens?
Less CO₂ absorbed
If temperature increases over time, what does it show?
Warming trend
What happens when forests are cut down?
Habitat loss + more CO₂
Why are electric cars better for the environment?
Less air pollution
What happens to global temperature over time?
It is increasing
Pollution in water → effect?
Harm to organisms
If ice levels decrease, what does that indicate?
Climate warming
Fertilizer runoff into water causes what problem?
Algae blooms / low oxygen
What is conservation?
Protecting natural resources
What happens to glaciers as temperature rises?
They melt
Increased greenhouse gases → effect?
Global warming
A graph shows CO₂ and temperature rising together. What is the relationship?
As CO₂ increases, temperature increases
Why does burning fossil fuels affect Earth systems?
Releases greenhouse gases → traps heat → climate change
Why are renewable resources better long-term?
Don’t run out + reduce pollution
What evidence shows climate change is happening?
Rising temps, melting ice, sea level rise
Explain how human actions lead to climate change
Burn fuels → CO₂ increases → heat trapped → temp rises
Why do scientists use graphs for climate data?
To identify patterns and trends over time
