How much has Earth's average temperature risen in the last 100 years?
0.6 Celsius
1 Fahrenheit

What causes scientists to believe that climate change is caused by human activity?
Because of how rapidly it is happening
Because of CO2 levels in the atmosphere
Because of the greenhouse effect
Because of the increased amount of forest fires
How can scientists compare CO2 levels between today and that of 650,000 years ago?
By observing air bubbles in ice cores from Antarctica and Greenland
By using a Delorean to observe the CO2 levels in person
By observing samples of ancient air trapped deep underground in caves.

20.2°
460°
What is defined as "the imaginary line between the North and South Pole"?
Axis
Equator

Climate
What is the hottest part of the Earth, and why?
The Equator, because it receives direct sunlight
The Equator, because it's closest to the Sun
The Polar Zones, because they receive direct sunlight
The Temperate Zones, because they're closest to the Sun
What are defined as "periods of time characterized by specific weather patterns and length of day and night"?
Seasons
Climate
Axis

Winter
Fall
Spring
During which season does Earth receive indirect sunlight? (Low angle, low intensity)
Summer
Winter
Fall
Spring
When the North Pole is tilted towards the Sun, in which hemisphere is it Winter?
Northern Hemisphere
Southern Hemisphere
When the North Pole is tilted away from the Sun, in which hemisphere is it Winter?
Northern Hemisphere
Southern Hemisphere
What is defined as "when the South Pole tilts towards the Sun, 24 hours of sunlight"? (Sun never sets, just circles the sky)
Midnight Sun
Polar Night
Antarctic Summer Jam
What is defined as "when the South Pole tilts away from the Sun, 24 hours of darkness"? (Sun is so low, it stays behind a glacier for the few hours it's up)
Polar Night
Midnight Sun
