Which of the following best describes the role of gravity in the solar system?

• It causes the planets to rotate on their axes.

• It keeps the planets in orbit around the Sun.

• It causes the Sun to emit light and heat.

• It determines the color of the planets.

Using a model of the Earth-sun-moon system, explain why solar eclipses do not occur every month.

• The Moon's orbit is tilted relative to the Earth's orbit around the Sun.

• The Sun's light is too strong to be blocked by the Moon.

• The Earth's atmosphere bends the Sun's light.

• The Moon is too far from the Earth to block the Sun.

Develop a model to describe how the tilt of Earth's axis affects the seasons.

• The tilt causes the Sun to be closer to Earth in summer.

• The tilt causes different parts of Earth to receive varying amounts of sunlight throughout the year.

• The tilt has no effect on the seasons.

• The tilt causes the Earth to rotate faster in summer.

Construct a scientific explanation for how the geologic time scale is organized based on rock strata.

• The geologic time scale is organized randomly.

• The geologic time scale is organized by the color of rock strata.

• The geologic time scale is organized by the sequence of rock layers, with older layers at the bottom.

• The geologic time scale is organized by the thickness of rock layers.
