2.

• More direct light; the southern hemisphere is tilted toward the Sun.
• More direct light; the northern hemisphere is tilted toward the Sun.
• More direct light; Earth is not tilted in any direction.
• Less direct light; the southern hemisphere is tilted away from the Sun

4. On August 21, 2017, there was a solar eclipse. Which of the following best represents the position of the Sun, Moon, and Earth during the total solar eclipse?

• The Sun, Moon, and Earth create a 90°.angle.
• The Sun, Moon, and Earth form a straight line with Earth in the center.
• The Sun, Moon, and Earth create a 45° angle.
• The Sun, Moon, and Earth form a straight line with the Moon in the center.

5. Summer occurs in the northern hemisphere during the part of Earth’s orbit when this half of Earth is tilted ___________ the Sun. This position makes the solar energy received from the Sun ________________direct and intense.

• away from, less
• away, from more
• towards, more
• towards, less

6. Winter occurs in the northern hemisphere during the part of Earth's orbit when this half of Earth is tilted ____________ the Sun. This position makes the solar energy received from the Sun __________________ direct and intense.

• away from, less
• away from, more
• towards, more
• towards, less

7.

• The distance from the Sun to the planets creates friction, which holds them in place.
• The Sun’s mass has no effect on the gravitational pull of the planets in the solar system.
• The inner planets have less mass, causing them to revolve more slowly around the Sun.
• The Sun’s mass creates a gravitational pull that holds the planets in the solar system in orbit

19. The orbital motions of the objects in the solar system are the direct result of which of the following features of the Sun?

• Its magnetic field
• Its brightness
• Its gravitational pull
• Its chemical composition

8. Scientists believe that the solar system formed when–

• a giant explosion occurred in the universe.
• there was a perfect alignment of the stars and galaxies.
• a cloud of gas and dust pulled together due to gravity.
• friction of the gas and dust occurred.

3. A lunar eclipse can only occur when the Moon lines up with Earth and the Sun in the position where the Moon normally would have been at which phase?

• First quarter moon
• Full moon
• Last quarter moon
• New moon

1. Two friends want to go midnight fishing during the next full moon in July. If there is a full moon on July 2, which of the dates below would be the most likely approximate date for the next full moon?

• July 9
• July 16
• July 23
• July 30

11. In a distant solar system, a planet orbits a star. The star has a certain mass (m1 ). The planet has a certain mass (m2 ). There is a certain distance between the planet and the star (d). Which of the following changes would INCREASE the amount of gravity between this star and this planet?

• Decrease the distance between the star and the planet (d)
• Decrease the mass of the planet (m2)
