What is one design solution that makes buildings safer during earthquakes?

Use flexible building designs and strong supports. Flexibility allows buildings to sway without breaking.
What is the meaning of impact when describing a hazard's effects?

The damage or harm caused by a hazard. Impact refers to the actual consequences when a hazard occurs.
What design solution reduces flood damage by lifting a house above high water?

Elevating the building on stilts or a raised foundation. Height keeps structures above typical flood levels.
Which design solution best reduces landslide risk on a steep slope?

Build a retaining wall and improve drainage. Walls hold soil; drainage removes water that weakens slopes.
Identify the best design solution to reduce injury risk on icy sidewalks: sand/salt or more water.

Spread sand or salt for better traction. Grit materials increase friction on slippery surfaces.
Which design solution best reduces flood damage to a home near a river?

Elevate the house above expected floodwater level. Raising homes keeps them above water during floods.
