6th Science REVIEW

Why can a solar eclipse only happen during a new moon?

• During a new moon, Earth is between the Moon and the Sun.

• During a new moon, the Moon is between the Sun and Earth.

• During a new moon, the Moon is fullest and blocks the sunlight best.

• During a new moon, Earth does not receive the light created by the Moon.

Which of the four hypothetical models that Josh and Paula came up with is MOST accurate?

• The Sun is a grain of sand. The edge of the solar system is in Augusta, Georgia. Proxima Centauri is in Sydney, Australia. The center of the Milky Way is on the Moon. Andromeda is just past Jupiter.

• The sun is a basketball. The edge of the solar system is about 3 meters away. Proxima Centauri is 10 kilometers down the road. The center of the Milky Way is in Augusta, Georgia. Andromeda is in Sydney, Australia.

• The Sun is a basketball. The edge of the solar system is a car length away. Proxima Centauri is the length of a football field away. The center of the Milky Way is in Augusta, Georgia. Andromeda is in San Francisco, California.

• The Sun is a grain of sand. The edge of the solar system is the length of a football field away. Proxima Centauri is in Augusta, Georgia. The center of the Milky Way is just over half the distance to Mars away. Andromeda is located where the real Sun is now.

Scientists have documented that galaxies they observe seem to be moving farther away. Which concept best explains this?

• black holes because an unseen force is pulling objects away from the center of the universe

• big bang theory because the universe exploded from a single point in space and is always expanding

• gravitational force because objects are being drawn toward the edges of the universe

• solar system because the mass of the Sun pushes other galaxies away

Four models of the Milky Way galaxy are shown, only one of which illustrates the correct location of the Sun.

Which model shows the correct location of the Sun in the Milky Way galaxy?

• model 1

  This model shows the Sun in the center of the Milky Way galaxy.

• model 2

  The Milky Way galaxy consists billions of stars organized into a dense center with arms spiralling outward. The Sun is located in a finger called the Orion Spur on one of the spiral arms.

• model 3

  This model shows the Sun too far away from the center of the Milky Way galaxy.

• model 4

  This model shows the Sun outside of the Milky Way galaxy.

A table with the diameter of the planets in Earth's solar system is shown below.

Using the table, which statement is true?

• Jupiter is about as wide as 11 Earths.

  This is the result of correctly comparing the size of Jupiter to the size of Earth.

• Mars is about as wide as 2 Earths.

  Mars is about half as wide as one Earth; it is not two times wider than Earth.

• Saturn is about as wide as 4 Earths.

  Uranus, not Saturn, is about as wide as 4 Earths

• Mercury is about as wide as 9 Earths.

  Mercury is smaller than Earth; it is not 9 times wider than Earth.

The diagram shows a model. Which theory does this model best support?

• special relativity

• heliocentric

• big bang

• geocentric

What causes one body to orbit another in space?

• A body's inertia attracts other bodies with the same inertia.

• A body's inertia is balanced by another body's pull of gravity.

• A body's gravity is overpowered by the inertia of another body.

• A body will orbit another body when their gravities are equal.

The graph shows the total number of hurricanes that have reached the coasts of the United States between 1851 and 2015.

A student predicts that the hurricane data for South America should show the same pattern. Which statement BEST describes why the student is correct or incorrect?

• The student is correct because hurricanes are more likely to form during warmer months.

  This is the result of correctly understanding the relationship between temperature and hurricane formation while ignoring that the warmest months differ in the Southern Hemisphere.

• The student is incorrect because hurricanes are more likely to form in the Northern Hemisphere.

  This is the result of incorrectly understanding the factors influencing hurricane formation. Hurricanes are equally likely to form in the Northern and Southern Hemispheres.

• The student is correct because more water evaporates from the oceans in August and September.

  This is the result of correctly understanding the relationship between evaporation and hurricane formation but neglecting to understand that the greatest amount of evaporation occurs during the warmest months in the Southern Hemisphere.

• The student is incorrect because the Southern Hemisphere is warmest in January and February.

  This is the result of correctly reasoning that, because hurricanes are formed by moisture evaporating from bodies of water, and because evaporation increases at higher temperatures, the Southern Hemisphere will experience the greatest number of hurricanes during the warmer months. Therefore, the graph will show the opposite pattern as the one shown.
