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

Look at the picture abov. Beased on this picture, why do the North and South poles of the Earth have much longer periods of light and darkness than the rest of the planet?

• The poles are angled toward or away from the Sun because of Earth's revolution.

• The rotation of the Earth is fast enough to keep the poles lit all the time.

• The Moon is closest to the poles, so it keeps those areas colder and darker.

• The Sun can never reach the poles because of the way the Earth is tilted.

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.

The moon reflects different amounts of sunlight onto Earth at different times. This reflected sunlight is commonly called moonlight.

• February 25, March 27, April 25, May 24
