A metal spoon becomes warm while resting in hot soup. Which process carries energy along the spoon?

Water rises from the heated bottom of a pot while cooler water sinks. What process does this circulation demonstrate?

Which process allows energy from the Sun to cross nearly empty space and warm Earth?

Which material would best slow heat flow through a cooking utensil's handle?

Why does a suitable plastic covering on a metal pot handle help protect a user's hand?

Wax holds paper clips along a metal spoon heated at one end. Which clip should drop first?

Warm water is placed beneath cooler water at room temperature. Why does the warm water rise?

At the same temperature, which surface is generally the best emitter of thermal radiation?

Roof finishes reflect 80%, 50%, and 20% of incoming sunlight. Assuming none passes through, which finish absorbs the least solar energy?

How does a narrow, sealed air gap between two windowpanes reduce heat transfer?

Which unwanted heat transfer is reduced most directly by weather stripping around an air-conditioned classroom's door?

Which earthquake-prone belt follows the rim of the central ocean in this map?

What do geologists call a fracture in Earth's crust along which rocks have moved?

Which type of fault is represented by the displaced layers and arrows?

Identify the fault shown in this cross-section.

The symbols show opposite movements toward and away from the viewer. Which fault type matches this diagram?

On an inclined fault, what is the rock block above the fracture plane called?

Which kind of stress pulls crustal rocks apart and commonly produces normal faulting?

A fault plane slopes 25 degrees from horizontal, and its upper block moves upward. What is this low-angle structure called?

Rocks beside a locked fault bend as stress builds. Which event releases stored elastic energy as an earthquake?

Why should a barangay avoid placing a building across a mapped active fault?

What earthquake feature does A identify?

Which letter marks the earthquake's epicenter?

What does an earthquake's magnitude describe?

Two towns report different shaking strengths from the same earthquake. Which measurement can differ between the towns?

Two earthquakes have similar depths, distances, and ground conditions near comparable buildings. What does a higher magnitude generally imply?

The houses have similar construction and ground conditions. Based only on distance from the source, which would generally experience stronger shaking?

A school site is far from every active fault mapped by PHIVOLCS. Which statement about its earthquake risk is correct?

A school audit finds weak load-bearing columns. Which measure directly reduces the building's structural earthquake vulnerability?

After shaking, boulders from a steep hillside block a road in Bohol. Which hazard has occurred?

Which seismic wave is represented by A?

Which material prevents S waves from passing through it?

Which surface wave produces the horizontal side-to-side particle motion shown here?

Which wave produces the rolling motion illustrated here?

Which measure is the maximum elevation reached by tsunami water on land, measured above sea level?

How does seafloor movement at B generate a tsunami in this model?

Must every undersea earthquake produce a tsunami?

A tsunami travels from deep ocean into shallower coastal water. How do its speed and height generally change?

Which description matches tsunami inundation?

Strong shaking stops in a coastal tsunami evacuation zone, but no official alert has arrived. What should the practiced evacuation plan direct residents to do?
