Why does the moon's gravitational pull have more of effect on tides than the sun's gravitational pull?

• they are the same
• the moon is larger than the sun
• tides are not caused by the moon
• the moon is closer to the Earth than the sun

This is a diagram of the inner solar system (not to scale) including the four inner planets, the asteroid belt, and the sun.  The orbital paths of the planets have been added.

The pattern of motion of objects in the solar system indicates that which of these planets will be revolving the fastest around the sun?

• Mercury

• Venus

• Earth

• Mars

Which of the following provides the best reasoning for a planet being able to form and maintain its spherical shape while also remaining in orbit around the Sun?

• The gravitational pull originating from the center of the planets allows them to retain their

  shape and the gravitational pull of the Sun keeps them in orbit.

• The gravitational attraction of planets towards neighboring planets allows them to retain

  their shape and the gravitational pull of the Sun keeps them in orbit.

• The gravitational pull originating from the center of the planets allows the planets to retain

  their shape and the magnetic force exerted on the planets by the Sun keeps them in orbit.

• The gravitational attraction of the planets towards neighboring planets allows them to

  retain their shape and the magnetic force exerted on the planets by the Sun keeps them

  in orbit.

Which statement below best describes how scientists explain gravity’s role in the formation of our Solar System?

• The combined gravitational attraction between our planets was so large that it pulled the

  Sun away from a nearby star cluster into the center of our Solar System.

• The eight planets in our Solar System were originally orbiting a nearby star, and the Sun’s

  gravity was large enough to pull those planets into orbit around the Sun.

• Due to the expansion of neighboring solar systems, the gravitational attraction of our

  planets to those solar systems forced the formation of the planets around our Sun.

• As the Sun was forming, the force of gravity caused surrounding dust grains to collide and

  stick together, forming dust granules into increasingly larger bodies that became planets.

Which of the following statements is the reason why the planets and stars are round?

• Gravity pushes out from the edge of the planet or star.

• Gravity pushes out from the center of the planet or star.

• Gravity pulls toward the center of the planet or star.

• Gravity pulls toward the edge of the planet or star.

Gravity has a significant role in the formation of our Solar System.  Which of the following provides the best reasoning for the role of gravity in the formation of individual planets and stars?

• Gravity keeps planets in orbit around the stars, helping them to form and maintain their shapes.

• Gravity pulls everything towards the center of a celestial body, allowing planets and stars to form and maintain their spherical shapes.

• The gravitational attraction towards the center of a galaxy results in the spiral formation of that galaxy and the formation of planets and stars.

• The gravitational attraction between planets and stars is responsible for the formation of larger gaseous planets and stars versus the smaller, rocky planets.
