Earthquake Impact and Tectonic Boundaries

The video from Clark Planetarium introduces viewers to earthquakes, focusing on tectonic plates and their boundaries. It explains the three types of plate boundaries: divergent, convergent, and transform, and how they relate to earthquake occurrences. The video also analyzes earthquake data, particularly in Utah, and discusses the concept of earthquake magnitude and depth. Finally, it addresses the challenges of predicting earthquakes, emphasizing that while science can identify risk areas, exact predictions are not possible.

What percentage of earthquakes occur along tectonic plate boundaries?

• 50%

• 75%

• 85%

• 95%

Which type of tectonic plate boundary is characterized by plates pulling away from each other?

• Transform

• Divergent

• Convergent

• Static

What color represents convergent boundaries in the video?

• Purple

• Green

• Red

• Blue

Which type of boundary is most associated with the majority of earthquakes?

• All equally

• Transform

• Convergent

• Divergent

What is a fault in the context of earthquakes?

• A type of earthquake

• A weak area in the Earth's crust

• A type of tectonic plate

• A measurement of earthquake strength

Where in the United States is a fault mentioned in the video?

• California

• Utah

• Nevada

• Alaska

What does the magnitude of an earthquake represent?

• The location of the earthquake

• The intensity or strength of the earthquake

• The duration of the earthquake

• The depth of the earthquake

How does the depth of an earthquake affect its impact?

• Deeper earthquakes are felt more

• Shallower earthquakes are felt more

• Depth has no effect

• Only deep earthquakes cause damage

Can scientists predict the exact time and location of an earthquake?

• Only for small earthquakes

• No, it's not possible

• Only in certain regions

• Yes, with high accuracy

What colors represent shallow and deep earthquakes in the video?

• Green and yellow

• Orange and purple

• Red and blue

• Black and white
