Which explanation is defensible for an investigation of reservoir operations and seasonal water availability?

• Seasonal river flows and managed water supplies support farms, energy, habitats, and communities.
• Snowmelt has no connection to summer streamflow.
• Irrigation eliminates the need to manage water shortages.
• River systems cannot cross state boundaries.

How should a student assess a claim involving idaho’s climate variation with altitude in Idaho?

• Rain shadows increase precipitation uniformly everywhere.
• All Idaho locations receive identical rainfall.
• Elevation, topography, and regional moisture patterns help produce different local climates.
• Mountain snowpack cannot affect downstream water supply.

• Southern Idaho consists entirely of ocean islands.
• Every region has identical elevation and climate.
• The Panhandle is a tropical coastline.

For an Idaho case study of interpreting land-area and total-area measurements, which statement is best supported?

• All square-mile measures include exactly the same features.
• Rocky landscapes are always more densely settled than cities.
• Physical terrain and the way it is measured affect settlement, travel, and comparisons.
• Elevation has no effect on transportation costs.

• Elevation has no effect on transportation costs.
• Rocky landscapes are always more densely settled than cities.
• All square-mile measures include exactly the same features.
• Physical terrain and the way it is measured affect settlement, travel, and comparisons.
