Idaho Geography

What does the evidence suggest when considering the influence of irrigation on crop choice in Idaho?

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

For an Idaho case study of idaho’s two time zones, which statement is best supported?

• Idaho has four time zones because it borders Canada.
• Idaho uses one time zone all year without daylight saving.
• Every county follows only Central Time.
• Different parts of Idaho follow Pacific and Mountain Time.

In studying orographic precipitation in idaho mountains, which conclusion can be justified?

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

When evaluating mountain snowpack and seasonal runoff, which interpretation is most accurate?

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

How should a student assess a claim involving drought risks for irrigation-dependent farming in Idaho?

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

Which principle is most relevant to understanding wildfire risks in forested idaho regions?

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

For an Idaho case study of the distinction between a city and a metropolitan area, which statement is best supported?

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

For an Idaho case study of why some volcanic landscapes become productive farmland, which statement is best supported?

• All Idaho canyons were excavated by glaciers last year.
• Volcanic rock forms only from river mud.
• The Snake River Plain is an ocean coral reef.
• Volcanic deposition and river erosion have both shaped parts of Idaho over geological time.

How should a student assess a claim involving contrasting the northern panhandle and snake river plain in Idaho?

• The Panhandle is a tropical coastline.
• Every region has identical elevation and climate.
• Southern Idaho consists entirely of ocean islands.
• Northern Idaho is narrower and often forested; southern Idaho includes broad valleys and the Snake River Plain.

Which principle is most relevant to understanding the rocky mountains’ influence on idaho geography?

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

For an Idaho case study of topographic relief in central idaho, which statement is best supported?

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