• Are there more galaxies beyond the Milky Way?

Which astronomer’s question BEST describes the solar system as we know it today?

• Astronomer A

• Astronomer B

• Astronomer C

• Astronomer D

Which BEST states how Earth and Mars are similar?

• They are similar in size.

• They share the same temperature.

• They are rockier more than gaseous.

Based on the model, what would the final step of his model?

• Move the ball around his head at arm’s length.

• Hold the ball stationary and move his head right to left.

• Have someone dim the light as you move the ball around his head.

• Try different size balls as you move the ball around his head at arm’s length.

What causes a solar eclipse?

• The earth moves over the sun and illuminates the moon.

• The moon moves over the sun and casts a shadow on the Earth.

• The sun moves over the moon and casts a shadow on the Earth.

• The earth moves over the moon and casts a shadow on both the sun and the moon.

Which statement is TRUE?

• Both Venus and Earth have diameters close in size.

• Both Neptune and Uranus have the closest distance to the sun.

• Both Mercury and Saturn are more rocky planets than gaseous planets.

• Both Mars and Jupiter have the same average temperatures on their respective planet.

Which position illustrates the alignment of the sun, Earth, and moon for a new moon phase?

• Position 1

• Position 3

• Position 7

• Position 5

Which statement explains the differences between meteoroids and asteroids?

• Asteroids have typical elliptical orbits and meteoroids have typical circular orbits around the sun.

• Asteroids are small solar system bodies that orbit the Sun. A meteoroid is a small rock or particle of debris in our solar system.

• Asteroids are generally smaller chunks of rock that dissolve once they enter Mars or Jupiter’s atmosphere. Meteoroids are made up of all the smaller objects in orbit around the moon.

• Most asteroids that enter the Earth’s atmosphere are so small that they vaporize completely and never reach the planet’s surface. Most of them originate from asteroids that lose gas and dust when they approach the Sun.

Which of the following BEST explains why there is more sunlight during the June Solstice in the Northern Hemisphere?

• The earth is tilted toward the sun in the Northern Hemisphere which provides more direct light.

• The earth is tilted away from the sun in the Northern Hemisphere which provides more direct light.

• The earth is tilted side to side in the Northern Hemisphere which provides more direct light.

• The earth is not titled in the Northern Hemisphere which provides more direct light.

Which TWO questions could be asked to disprove the theory seen in the image?

• How far is the Sun from Earth?

• What causes night and day on Earth?

• What causes the Moon to change shapes?

• What other objects can be seen orbiting in the sky?

• How does the tilt of Earth contribute to the seasons on Earth?
