Which principle is most relevant to understanding geomorphic evidence for hells canyon incision histories?

• 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.
• All Idaho canyons were excavated by glaciers last year.

For an Idaho case study of geochronological interpretations of snake river plain volcanism, which statement is best supported?

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

Which principle is most relevant to understanding assessing physiographic regionalization methods for idaho?

In studying topographic constraints in idaho transport network modeling, which conclusion can be justified?

• Rocky landscapes are always more densely settled than cities.
• 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.
