Why is the increase of Greenhouse gasses a big issue?

• It causes climate change and increase in the global temerature 
• It can lead to a major increase in Greenhouses 
• It leads to more factories
• It causes a major decrease in people

How can global warming cause sea levels to rise? Choose the best answer.

• by causing it to rain more often
• by melting glaciers and ice caps
• by increasing the number of undersea volcanic eruptions
• by creating bigger and more powerful hurricanes

The graph below shows CO_2 emissions and temperatures from 1909 to 1949. What conclusion is best supported by the graph?

• There is no relationship between carbon dioxide concentrations and temperatures

• As carbon dioxide concentrations increase, temperatures increase

• As carbon dioxide concentrations increase, temperatures decrease

• As carbon dioxide concentrations decrease, temperatures increase

What is the greenhouse effect?

• A natural process where gases trap heat in the atmosphere.

• A man-made process where gases trap heat in the atmosphere.

• A natural process where the ocean traps heat in the atmosphere.

• A man-made process where the ocean traps heat in the atmosphere.

According to the data shown on greenhouse emissions, Which two greenhouse gases are major contributors to greenhouse emissions? Select two.

• HCFs

• nitrous oxide

• methane

• carbon dioxide

How does deforestation contribute to climate change?

• By increasing the amount of oxygen in the atmosphere

• By reducing the Earth's temperature

• By decreasing the amount of carbon dioxide absorbed from the atmosphere

• By increasing the Earth's albedo
