Module: Natural Hazards
DCI: ESS3.B Natural hazards and other geologic events have shaped
the course of human history. They have significantly altered the sizes of human
populations and have driven human migrations.
PE: HS-ESS3-1 Construct on explanation based on evidence for how
the availability of natural resources, occurrence of natural hazards, and
changes in climate have influenced human activity.
[Clarification
Statement: Examples of key natural resources include access to fresh water
(such as rivers, lakes, and groundwater), regions of fertile soils such as
river deltas, and high concentrations of minerals and fossil fuels. Examples of
natural hazards can be from interior processes (such as volcanic eruptions and
earthquakes), surface processes (such as tsunamis, mass wasting and soil
erosion), and severe weather (such as hurricanes, floods, and droughts).
Examples of the results of changes in climate that can affect populations or
drive mass migrations include changes to sea level, regional patterns of
temperature and precipitation, and the types of crops and livestock that can be
raised.]
The basic content of the standard is as follows.
- Human history has been affected by hazards and other geologic events.
- The effects of hazards and geologic events on humans include changes to population size and migrations.
