The graphic shows the stages in the development of
the solar system.Which statement best describes
the process of the formation of the solar system?
a. | Gravity pulled the gas and dust together. | b. | Magnetism attracted
the gas and dust together. | c. | An explosion pushed the gas and dust together.
| d. | A black hole pulled the gas and dust together. |

According to the Nebular Theory, the largest mass of matter in a nebula will
form into a star and the smaller masses of matter will form into planets. Earth In Orbit Around the Sun | . . | | How does the Nebular Theory explain why
planet Earth revolves around the Sun instead of the Sun orbiting around the Earth?
a. | The Sun orbits around Earth. This can be observed by watching a sunrise or
sunset. | b. | The Nebular theory states that non-contact forces (pushing forces) cause this
effect. | c. | The Sun contains the most matter in our Solar System, so it also has the most
gravity. | d. | Cause: Dark matter in space, Effect: Earth is forced to
revolve around the Sun |

When the solar system was very young, the sun was
just being formed and planets had not yet been made. The solar system was mostly gas and
dust.
Which statement best explains how planets formed in the early solar
system?
a. | Planets formed from clusters of debris that were attracted together because of
gravity. | b. | Planets formed from large asteroids that had broken apart. | c. | Planets formed from
magnetism in space that interacted with light from the stars. | d. | Planets formed from
molten metal in volcanic eruptions. |

When our solar system was forming from a nebula
about 4.6 billion years ago, there were two large masses of matter. The largest mass became the Sun.
The second largest mass became planet Jupiter. The largest cluster of atoms that became the Sun had a mass of about 1.989 x
1030 kilograms, and the mass that became Jupiter had a mass of about 1.898 x
1027 kilogram What most likely would have
happened if the mass of atoms that formed into Jupiter had been equal to the mass that formed into
our Sun?
a. | Electrostatic repulsion would have forced one mass to leave our solar
system. | b. | They would have combined to form a black hole at the center of our
galaxy. | c. | The masses would have canceled each other out so that no star would have
formed. | d. | Each mass would have formed a separate star resulting in a binary
system. |

In the Earth-Moon system, our planet’s gravitational force affects the
Moon while at the same time the Moon’s gravitational force affects the Earth. How does the Moon’s
gravity cause the rise and fall of Earth’s ocean levels?
a. | The Moon’s gravity “pulls” on Earth’s air causing winds to
form large ocean waves. | b. | The Sun’s gravitation force
“pulls” on both the Earth and the Moon at different times. | c. | The Moon’s
gravitational force “pulls” on the oceans as planet Earth rotates. | d. | Earth’s
revolves on its axis, which causes oceans levels to rise facing the
Moon. |

The Nebular Theory describes and explains how solar
systems start as huge clouds of cosmic dust called nebulas and are changed into stars and planets by
gravity. Select the choice below that correctly
orders the steps of the Nebular Theory.
a. | Step One: Our entire universe existed as a tiny point of energy. Step
Two: This tiny point rapidly expanded/inflated (The Big Bang Theory). Step Three:
Sub-atomic particles formed into the first atoms (helium and oxygen). Step Four: Gravity
compressed clouds of helium to form the first stars. | b. | Step One: The Big Bang occurred
resulting in the rapid expansion of our universe. Step Two: Solar systems began to form not
long after the Big Bang. Step Three: Our solar system was the very first one to
form. Step Four: Today, dark energy is pushing all other solar systems away from our
sun. | c. | Step One: Gravitational attraction in a nebula pulled together clumps of
atoms. Step Two: The largest clump formed into Jupiter, our largest planet. Step
Three: One of the smaller clumps formed into planet Earth. Step Four: After the
planets formed, nuclear fusion occurred to form the Sun. | d. | Step One:
Gravity pulled together atoms in a nebula into larger and larger clumps. Step Two: The
largest clump of matter (mostly hydrogen) began to heat up. Step Three: Nuclear fusion
occurred in this largest clump, and a star was formed. Step Four: Smaller clumps of matter
around the star formed into planets. |

Gravity formed our solar system from a cloud of elemental particles (mostly
hydrogen and helium) about 4.6 billion years ago. The force of gravity continues to affect objects in
our solar system today including the Earth and the Moon. Earth-Moon
System | . . | | What are two cause and effect connections that accurately describes
gravity’s role concerning the Earth-Moon system?
a. | One: The Moon’s primary motion in the Earth-Moon system is called
rotation. Two: Since the Moon is moving away from the Earth, it is red
shifted. | b. | One: The Moon’s gravity causes tides to occur on Earth’s oceans. Two:
Since the Moon has less mass than our planet, the Moon orbits around the Earth. | c. | One: In the
Earth-Moon system, the Moon revolves around the Earth. Two: Since the Moon has more mass then the
Earth, the Moon’s gravity causes tides. | d. | One: The Moon orbits around the Earth at the
speed of light. Two: The Earth’s gravitation pull on the Moon causes the earth to
rotate. |

Spring Tides: refers to the 'springing forth' of the tide
during new and full moons. Neap Tides: occurs seven days after a spring tide, refers to a
period of moderate tides. Contrast

tides are formed. (Select two choices).
