Test on Solar System

Which statement is NOT part of Kepler's Laws on Planetary Motion?

• Planets move through orbits faster in some places than in others.
• Planets that are far from the sun take longer to orbit the sun.
• Orbits are counter-clockwise and elliptical.
• The motion of a planet around the sun is the result of gravity and inertia.

What are Jovian planets formed far from the sun?

• Less affected by the sun, gases stayed and planets grew large
• Became so hot from sun that gases mostly boiled away, leaving rock
• Inner planets were formed by the collision of hydrogen nuclei to form helium
• Outer planets were formed by the collision of metals and other debris

A lunar eclipse occurs when the Earth passes between the Moon and the Sun, however a solar eclipse occurs when —

• the Moon passes between the Earth and the Sun
• the Sun passes between the Earth and the Moon
• the Earth passes between the Moon and the stars
• the Moon passes between the stars and the Earth

Which of the following CORRECTLY describes the Solar Nebular Theory?

• The solar system was formed from a disk of dust and gas orbiting a newly formed star.
• The solar system is made of planets that move through orbits faster in some places than in others
• The solar system was formed from the gases released by a dying star.
• The solar system was formed by the collision of metals and other dense materials in space.

Which of the following caused gases and debris to condense?

• gravity
• orbit
• nuclear fusion
• inertia

Which TWO factors resulted to the formation of planetary orbits?

• gravity and inertia
• nuclear fusion and fission
• revolution and rotation
• eccentricity and elliptical

Which statement correctly describes revolution?

• the length of time it takes for a planet to complete its orbit
• the length of time it takes for a planet to complete a turn on its axis
• the length of time it takes for light from the sun to reach the earth
• the length of time it takes for the sun to continually undergo nuclear fusion

Which statement is TRUE about the data table provided below?

• Planets move through orbits faster in some places than in others.
• Planets that are far from the sun take longer to orbit the sun.
• Orbits are counter-clockwise and elliptical.
• The motion of a planet around the sun is the result of gravity and inertia.

What causes this cycle of the Earth's changing seasons?

• Earth's tilt as it revolves around the Sun
• Moon revolving around the Earth
• Earth spinning on its axis every 24 hours
• Planets revolving around the Sun

A lunar eclipse occurs when the Earth passes between the Moon and the Sun, however a solar eclipse occurs when —

• the Moon passes between the Earth and the Sun
• the Sun passes between the Earth and the Moon
• the Earth passes between the Moon and the stars
• the Moon passes between the stars and the Earth
