Global Climate Change

Where has the temperature changed the most?

• central latitude
• central longitude
• north pole
• south pole

Describe the average temperature change from 1880 to 2010.

• increase by more than 0.8

• increase by 0.6
• increase by 0.4

Why are these error bars smaller near the year 2000 than in the 1890s?

• better graphing technique
• better technology
• Someone made a mistake
• worse methods of collecting data

How does atmospheric carbon dioxide affect global temperature?

• more CO2, lower temperature
• less CO2, lower temperature
• less CO2, higher temperature
• more CO2, higher temperature

What two things can happen when energy from the Sun interacts with the ground?

• absorbed & reflected
• absorbed & refracted
• absorbed & transmitted
• reflected & refracted

What happens if you remove all of the carbon dioxide from the atmosphere? The temperature:

• decreases
• increases
• stays the same

What happens when sunlight hits greenhouse gas molecules?

• quickly cools them, decreasing temperature
• slowly cools them, decreasing tempature
• quickly heats them, increasing temprature
• slowly heats them, increasing temperature

How do carbon dioxide (CO2) and other greenhouse gases cause Earth's atmosphere to warm?

• absorb incoming solar radiation
• reflect incoming solar radiation
• absorb outgoing infrared radiation
• emit outgoing infrared radiation.

What is one cause of the carbon dioxide increase over the past 50 years?

• tree farms
• fossil fuel use
• medicine
• technology

What happens when energy from the Sun encounters a white surface (ice or snow)? The energy is:

• reflected off the surface and leaves the atmosphere
• reflected off the surface and trapped in the atmosphere
• absorbed by the surface and stored in the land and ocean
• absorbed by the surface, radiating heat into the atmosphere
