Natural Hazards
Grade 4 - Science - Challenge Me
Community safety review: which natural hazard fits this evidence: coastal storms bring high winds and storm surge?
- flood
- hurricane
- earthquake
- wildfire
Hazard plan: what impact can a blizzard have?
- shaking can knock shelves and buildings loose
- travel can become unsafe
- soil and rocks can slide downhill
- fire can spread quickly through dry plants
Preparedness comparison: which solution best reduces the impact of a landslide?
- clear dry brush away from buildings
- use storm shutters and plan evacuation routes
- anchor shelves and practice drop-cover-hold drills
- plant deep-rooted vegetation and avoid building at the slope base
Community safety review: which comparison supports the solution for a blizzard?
- prepared supplies help during blocked travel better than no supplies
- raised equipment stays drier than equipment on the floor
- cleared space slows fire spread better than brush against walls
- deep roots help hold soil better than bare slopes
Risk-reduction design: why is "build a shade tent for hot afternoons" a weak solution for an earthquake?
- it does not match the hazard's likely impact
- it addresses the most likely damage
- it directly reduces the named impact
- it was chosen after comparing hazard evidence
Hazard plan: which natural hazard fits this evidence: the town is beside a river that rises after heavy rain?
- blizzard
- landslide
- hurricane
- flood
Preparedness comparison: what impact can a landslide have?
- soil and rocks can slide downhill
- water can cover roads and enter buildings
- wind and water can damage homes
- fire can spread quickly through dry plants
Earth-process evidence: which solution best reduces the impact of a hurricane?
- remove all weather forecasts from the town
- raise equipment and mark evacuation routes
- use storm shutters and plan evacuation routes
- anchor shelves and practice drop-cover-hold drills
Earth-process evidence: which comparison supports the solution for a wildfire?
- cleared space slows fire spread better than brush against walls
- 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
Earth-process evidence: why is "paint warning signs on loose rocks only" a weak solution for a landslide?
- it does not match the hazard's likely impact
- it addresses the most likely damage
- it was chosen after comparing hazard evidence
- it directly reduces the named impact
