The topographic map shows the location of a park ranger at Point X when a message is received that an injured hiker needs help at Point Z. Which of these is closest to the difference in elevation between the locations of the ranger and the injured hiker?

• 2,050 m

• 450 m

• 910 m

• 3,650 m

What is the difference in elevation in meters between Point X and Point Y on the map?

A student stands at the point marked X on the topographic map below. What height in meters must the student climb in order to reach the top of the hill?

The points labeled W and Y on the topographic map below show the campsites of two families. Each family hiked to the elevation on the map marked X. The arrows show the paths taken by both families.What was the change in elevation, to the nearest ten meters, for the family that took the steepest path to Point X?

A river area is shown on the topographic map. Four riverbank areas are labeled on the map. Which two riverbanks are the steepest?

• W and X

• Y and Z

• X and Y

• W and Z

A Hertzsprung-Russell diagram is shown below. Based on this diagram, which type of stars would belong to spectral class M and have the highest luminosity?

• Main-sequence stars

• Giants

• White dwarfs

• Supergiants
