Some earthquakes are too small for humans to experience.

• True
• False

Engineers are able to prevent all natural hazards.

• True
• False

Engineers design a wall to redirect lava away from buildings. Lava is able to burn through quickly during its first test. What is a reasonable next step?

• Make the wall thinner.
• Create a new material for the wall.

What is an Earth Process

• Something that changes the Earth
• The quick way water runs downhill.

What is a quick change?

• volcano erupting
• mountains moving

What is a slow change?

• erosion
• tsunami

What is one engineering solution to earthquakes?

• Seismic base isolators
• Ground movement dampeners

How do tiltmeters help redict eruptions?

• Ash in the air precedes an eruption.
• Magma buildup changes the slope.

What causes tsunamis?

• undersea earthquakes
• glaciers falling into oceans

How does a tsunami buoy work?

• It detects flowing lava.
• It detects crust pressure.
