2. Suppose you see the constellation Ursa Major
Suppose you see the constellation Ursa Major. How will this constellation look if you view it from the same place six months from now?
It will look different because Earth will have orbited halfway around the sun.
It will look different because stars move across the sky.
It will look the same because stars do not change their positions in the sky.
It will look different because Earth will have rotated on its axis.

3. 2. For an astronomer, the best instrument for viewing a distant star is
A telescope
A microscope
A pair of binoculars
The Hubble Space Telescope

4. Use the picture to help you answer question 3. 3
Use the picture to help you answer question You can see one phase of the moon in the picture. Which phase comes next?
Half moon
First quarter
Third quarter
The new moon

5. 4. The cycle of the moon’s phases can be seen from Earth because
The moon revolves around Earth.
The moon’s distance from Earth changes at a predictable rate.
The moon spins on its axis.
The moon’s axis is tilted.

6. 5. In the water cycle, water in the ocean evaporates
5. In the water cycle, water in the ocean evaporates. Water vapor moves up into the atmosphere, where it cools. What happens to the water vapor when it cools?
The water vapor melts.
The water vapor changes into hail.
The water vapor evaporates.
The water vapor condenses.

7. 6. Summer days in the Northern Hemisphere are hotter than winter days, because in the summer
Earth is closer to the sun.
The number of sunspots increases.
Earth’s Northern Hemisphere is tilted toward the sun.
The sun gives off more energy.

8. Use the weather map below to answer question 7. 7
Use the weather map below to answer question What is the weather in Savannah likely to be in the next few days?
A warm front will soon pass over, so weather will be cooler and drier.
A warm front will soon pass over, so weather will be warmer and humid.
A cold front will pass over, so weather will be cooler and drier.
A cold front will pass over, so weather will be warmer and more humid.

9. 8. Which of these indicates a change in climate?
The air temperature increases by two degrees over a period of thirty years.
In the spring, rains are unusually heavy and the area is flooded.
An early snowfall blankets the region and damages power lines.
October shows record rainfalls that cause floods.

10. Use the picture to answer questions 9 and 10.
What change in state is MOST likely to happen as the ice warms up?
From liquid to gas
From solid to liquid
From gas to solid
From solid to gas
What is the temperature of the ice cubes?
At or below 0°C
Above 0°C
Just below 100°C
100°C

11. A star’s color tells us about its
Size
Temperature
Rotation
Distance from earth

12. 12. The weather is very cold and the air is filled with water vapor
12. The weather is very cold and the air is filled with water vapor. These are good conditions for
Sleet
Snow
Hail
Rain

13. Use the picture to answer questions 13 and 14.
What is happening at the arrow labeled B?
Water is evaporating
Water is freezing
Water is condensing
Water is falling as precipitation
14. How does water at arrow A form a cloud?
The water freezes
The water evaporates
The water condenses
The water precipitates

14. 15. If winter wind is blowing from the north, the weather is likely to get colder. Which instrument could help you decide which coat to wear to school?
Anemometer
Barometer
Hygrometer
Weather vane

15. 16. Which statement correctly describes the outer planets?
The outer planets are warmer than the inner planets.
The outer planets are smaller than the inner planets.
The outer planets have rocky surfaces.
The outer planets are made mostly of gases.

17. 18. Which is NOT true of sleet and snow?
They both form cumulonimbus clouds.
They both result from condensation.
They both form as liquid water freezes.
They both are forms of precipitation.

18. 19. On a weather map, warm fronts are indicated by
The letter H
The letter L
A blue line with triangles
A red line with half circles
