Natural Hazards
Grade 4 - Science - Building Confidence
Hazard plan: which natural hazard fits this evidence: coastal storms bring high winds and storm surge?
- wildfire
- hurricane
- landslide
- earthquake
Community safety review: what impact can a hurricane have?
- soil and rocks can slide downhill
- shaking can knock shelves and buildings loose
- water can cover roads and enter buildings
- wind and water can damage homes
Risk-reduction design: which solution best reduces the impact of a landslide?
- raise equipment and mark evacuation routes
- use storm shutters and plan evacuation routes
- plant deep-rooted vegetation and avoid building at the slope base
- anchor shelves and practice drop-cover-hold drills
Community safety review: which comparison supports the solution for a landslide?
- raised equipment stays drier than equipment on the floor
- planned evacuation routes protect people better than waiting without a plan
- deep roots help hold soil better than bare slopes
- prepared supplies help during blocked travel better than no supplies
Community safety review: why is "store extra snow shovels by each classroom" a weak solution for a flood?
- it addresses the most likely damage
- it does not match the hazard's likely impact
- it directly reduces the named impact
- it was chosen after comparing hazard evidence
Hazard plan: which natural hazard fits this evidence: the area sits near an active fault?
- hurricane
- blizzard
- earthquake
- landslide
Earth-process evidence: what impact can a hurricane have?
- travel can become unsafe
- fire can spread quickly through dry plants
- water can cover roads and enter buildings
- wind and water can damage homes
Preparedness comparison: which solution best reduces the impact of a hurricane?
- use storm shutters and plan evacuation routes
- anchor shelves and practice drop-cover-hold drills
- raise equipment and mark evacuation routes
- clear dry brush away from buildings
Earth-process evidence: which comparison supports the solution for a flood?
- prepared supplies help during blocked travel better than no supplies
- raised equipment stays drier than equipment on the floor
- deep roots help hold soil better than bare slopes
- planned evacuation routes protect people better than waiting without a plan
Earth-process evidence: why is "remove all weather forecasts from the town" a weak solution for a hurricane?
- it was chosen after comparing hazard evidence
- it addresses the most likely damage
- it does not match the hazard's likely impact
- it directly reduces the named impact
