• Genesis 1: 1-4
• Genesis 2: 1-4

• Genesis 2: 1, 4

In our solar system the largest objects besides the sun are.....

• planets
• dwarf planets
• asteroids
• moons

Scientist theorize that our solar system was formed about 4.6 billion years ago.  Which of the following best describes their theory of formation.

• meteorites
• comets
• moons
• planets

Which of the following is the best way to describe the difference between a planets and a dwarf planets?

• Planets are big and dwarf planets are small.  Dwarf planets do not orbit the sun.
• Planets are massive objects that orbit the sun.  Dwarf planets are nearly spherical and orbit planets.
• Planets are massive objects that orbit the sun and are the only object in their orbital path around the sun.  Dwarf planets are nearly spherical and share their orbital path around the sun with other objects of similar size.
• Planets are nearly spherical objects that orbit the sun and share their orbital path around the sun with other objects of similar size.  Dwarf planets are massive objects that orbit the sun and are the only object in their orbital path.

Which is a list of other objects that are in our solar system besides planets, dwarf planets and the sun?

• moons, meteoroids, asteroids, and comets
• moons, meteoroids, stars, and comets
• meteors, stars, moons and comets
• None of the following choices are correct.

An asteroid and comet are both small rocky objects. However a comet has one more quality that makes it different.  What is it?

• firey
• drippy
• watery
• icy

Which of these choices best describes the inner planets?

• They are rocky and made of soft elements including gasses.  Their cores are mostly iron and they are the smaller of our 8 planets.  They have a lot of moons.  They rotate slowly and have rings.
• They are rocky and made of heavy elements including metals.  Their cores are mostly gold and they are the larger of our 8 planets.  They have few or no moons at all.  They rotate quickly and have no rings.
• They are rocky and made of heavy elements including metals.  Their cores are mostly iron and they are the smaller of our 8 planets.  They have few or no moons at all.  They rotate slowly and have no rings.
• They are rocky and made of heavy elements including metals. Their cores are mostly silver and they are the smaller of our 8 planets.  They have few or no moons at all.  They rotate quickly and have no rings.

This planet is the smallest planet and closest to the sun.  It has no atmosphere and has surface craters like our moon.

• Mercury
• Venus
• Earth
• Mars

This planet is nearly the same size as Earth.  It has the slowest rotation.  Its atmosphere is thick CO₂ and its heavy clouds trap the sun's energy making it the hottest planet.

• Mercury
• Venus
• Earth
• Mars

This planet is the largest of the inner planets and has large amounts of liquid water.  Its atmosphere is 78% nitrogen and 21% oxygen.  It also supports life for plants, animals, and humans.

• Mercury
• Venus
• Earth
• Mars
