Global Warming

Multiple Choice

What does the entire scientific community agree upon?

• Earth's temperature is increasing

• Earth's temperature is decreasing

• Global warming occurs due to the suns energy output.

• Carbon dioxide is the cause of global warming

​Global temperatures have risen by 2% since 1850.

​Polar bears use the sea ice to help them search for food.

Multiple Choice

What effect does the ice melting have on polar bears?

Multiple Choice

Do you know which of these factors is causing sea level to rise?

• the activity of the moon

• the presence of fishes in the sea

• global warming

• volcanoes activity

​Coral bleaching is primarily caused by rising ocean temperatures due to climate change, but other factors like pollution, low tides, and excessive sunlight.

Multiple Choice

What causes coral bleaching?

• oil spills

• warmer water temperatures

• overfishing

• red tide

​In the last 100 years, atmospheric carbon dioxide (CO2) levels have increased significantly. Pre-industrial levels were around 280 parts per million (ppm), and today they are near 425 ppm, representing an approximate 50% increase.

Multiple Choice

How is the greenhouse like the earth's atmosphere? Pick the answer that relates to the lesson!

• Both have a glass roof

• Both trap heat

• Both have greenhouse gases

• Both support life

Multiple Choice

The graph below shows CO2 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

Global warming increases evaporation rates, making places drier and more susceptible to drought. 

Multiple Choice

Desertification includes natural processes and humans.

• True

• False

​Global warming can contribute to increased flood risk by intensifying precipitation events and raising sea levels

Multiple Choice

A warmer world is least likely to result in...

• decreased food production
• desertification

• a rise in sea level
• more moderate weather

​Certain gases, like carbon dioxide and methane, absorb infrared radiation (heat) that the Earth emits after absorbing sunlight, preventing it from escaping into space.

Multiple Choice

The diagram represents solar energy that is absorbed by Earth's land and water surfaces and is changed into heat that radiates back into the atmosphere.What is this process called?

• ozone
• radiation
• greenhouse effect
• evaporation

​An increase in greenhouse gas concentrations, primarily due to human activities like burning fossil fuels, can lead to a heightened greenhouse effect, resulting in global warming and climate change.

Multiple Choice

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.

Multiple Select
