Human Activity
What can humans do to prevent carbon dioxide emissions?
Switch to renewable energies
Heat from the sun gets trapped in Earth's atmosphere.
What are the two main greenhouse gases produced by humans?
Carbon Dioxide and Methan
What is an environmental effect that is irreversible?
Species Extinction
What are three types of renewable resources?
Wind, Sun, Biomass, Water (hydroelectric)
What is the main human activity that contributes to climate change?
Burning fossil fuels
How does the greenhouse effect help our Earth?
Without the Greenhouse effect, Earth would be too cold for life.
Name two ways Carbon Dioxide can be produced.
Factories, Driving Cars, Burning Fossil Fuels, Natural Gas, Coal and Oil for energy.
Why should we care about protecting biodiversity?
Once a species goes extinct, they cannot be brought back
What are three types of nonrenewable energies?
Coal, Oil, Natural Gas, Nuclear Energy
Which human activity contributes the most to METHANE production?
Agriculture and Livestock Farming
What method would be most effective in reducing greenhouse gas emissions?
Replacing Nonrenewable Energy with Renewable Energy (example: replacing Coal with Solar Panels)
What is the main way that methane is produced?
Agriculture and Farming Livestock
Why should people be aware of the impact of their actions on the enviornment?
The depletion of finite resources cannot be reversed
Why is it challenging to replace our nonrenewable resources?
Renewable resources do not produce enough energy.
What is a major cause of global climate change?
Driving Cars
What are three gases that prevent heat from leaving our atmosphere?
Carbon Dioxide, Sulfer Dioxide, Methane, and Water Vapor.
What is the relationship between Carbon Dioxide and Global Temperatures?
More Carbon Dioxide leads to higher global temperatures.
How does deforestation contribute to climate change?
It reduces the number of trees that can absorb carbon dioxide
What makes fossil fuels different from renewable resources?
Fossil fuels cannot be replaced once they run out
What type of transportation has the LEAST impact on Climate Change?
Riding a bike, walking, anything that does not use gas or creates emissions.
How much have global temperatures risen since 1850?
About 2 degrees F
What is the primary source of Carbon Dioxide emissions worldwide?
Burning Fossil Fuels for energy
How could pollution affect marine life?
It can cause harm to aquatic species and disrupt food chains
What happens to finite resources like oil and coal?
They will eventually run out if we continue using them.
