Earthquake Intensity and Function Analysis

The video discusses the 2008 Sichuan earthquake, highlighting its devastating impact and the nonlinear nature of earthquake magnitude. It explains how earthquake intensity is mapped using color-coded maps and the role of exponential functions in modeling this intensity. The video emphasizes the localized damage caused by earthquakes and introduces exponential functions as a tool for understanding these phenomena.

What major event did China host in August 2008?

• Expo

• Olympics

• World Cup

• G20 Summit

What was the magnitude of the Sichuan earthquake on the RTOR scale?

• 8.2

• 6.5

• 7.9

• 7.5

Where does the most damage occur during an earthquake?

• In the mountains

• In the surrounding cities

• At the fault line

• At the epicenter

How does earthquake damage change as you move away from the epicenter?

• It decreases dramatically

• It fluctuates

• It remains constant

• It increases

What type of function best models the intensity of an earthquake?

• Linear function

• Logarithmic function

• Quadratic function

• Exponential function

What does a color-coded map from the US Geological Survey show?

• Population density

• Earthquake intensity

• Traffic flow

• Weather patterns

What would a linear function indicate about earthquake damage?

• Damage is localized

• Damage is minimal

• Damage spreads evenly

• Damage is unpredictable

How does an exponential function differ from a linear function in terms of value change?

• It does not change

• It changes in constant steps

• It changes in big leaps

• It changes in small steps

What would a map look like if earthquake intensity followed a linear function?

• A sudden change from red to green

• No change in color

• Random color patches

• A gradual change from red to green

What is the distance from the red area to the green area on the earthquake intensity map?

• 50 km

• 100 km

• 150 km

• 200 km
