Science Category 4 STAAR

The Hertzsprung-Russell diagram below shows how the brightness, surface temperature, and color of stars are related. Which of these observations of Barnard’s Star is most likely accurate?

• Barnard’s Star is less bright than the sun, has a surface temperature below 3,800 K, and is red.

• Barnard’s Star is less bright than the sun, has a surface temperature above 3,800 K, and is red.

• Barnard’s Star is brighter than the sun, has a surface temperature below 5,300 K, and is yellow.

• Barnard’s Star is brighter than the sun, has a surface temperature above 5,300 K, and is yellow.

Most stars in the universe fit into one of the four areas on this Hertzsprung-Russell diagram. Which area of the diagram represents the white dwarfs?

• Star 1

• Star 2

• Star 3

• Star 4

The diagram below shows a model of the movement of two tectonic plates. When the plates collide, one plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce —

• fossil layers

• volcanic islands

• deep-sea sediment

• seafloor spreading

The San Andreas fault is a transform fault. The map below shows a student’s approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years. Which map best predicts the likely movement of land along the fault line over thousands of years?

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?

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?

When the Northern Hemisphere is tilted away from the Sun —

• the South Pole is pointing directly at the Sun.

• it is summer in the Southern Hemisphere.

• it is night in the Northern Hemisphere.

• the Sun's rays do not strike the Northern Hemisphere.
