The Big Bang Theory

States that the universe started as a dense sphere of matter that rapidly expanded producing all matter that now exists in the universe. The assemblage of matter started with element 1 Hydrogen.

Multiple Choice

According to the big bang theory which element MOST likely formed first?

• carbon dioxide

• hydrogen

• oxygen

• nitrogen

Multiple Choice

The diagram is an illustration of the

• solar nebula theory

• Big Bang theory

• evolution of our galaxy

• beginning of the Earth

The Life Cycle of a Star

• Stage 1: Stellar Nebulae (Nebula)

• Stage 2: Main Sequence or Massive Star

• Stage 3: Red Giant

• Stage 4: Planetary Nebula or Supernova

• Stage 5: White Dwarf, Neutron star, or Black Hole

• The Pathway the star goes depends on Mass

Multiple Choice

A star begins its formation as gravitational forces cause instability within a --

• supernova

• black hole

• red giant

• nebula

Multiple Choice

Most Stars in Milky Way are like the Sun. The Sun will eventually become a red giant. After the red giant, what determines whether a star will become a white dwarf or a supernova?

• the mass of the star

• the diameter of the star

• the brightness of the star

• the type of gas in the star

Multiple Choice

Nuclear Fusion is the main energy source of stars. Which reaction is shows fusion?

• Si --> Fe + Ni

• He --> C + O

• Ne --> O + Mg

• H + H --> He

The Solar System

• Planetary Order: Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

• The Earth is special because it is in the perfect position to maintain liquid water.

• All planets revolve around the sun in the same direction

Multiple Choice

Spacecraft traveling to Jupiter from Earth would most likely have to navigate through or around which natural obstacle?

• Asteroid Belt

• Neptune

• Comet's Tail

• Uranus

Multiple Choice

Due to the proximity of the Earth to the sun

• The seasons are the about the same

• the moon was formed

• the day night cycle are constant

• temperatures are hospitable to life

Multiple Choice

Which characteristic due all planets in our solar system have

• Direction of revolution

• Percentage of atmospheric gases

• features of a rocky crust

• angle of axial tilt

Multiple Choice

India is in the Northern Hemisphere and Australia is in the Southern Hemisphere. In June, it is summer in India and winter in Australia. What is the main reason the seasons are opposite in the two countries?

• because Earth is titled on its axis

• because the sun rotates on its axis

• because the earth revolves around the sun

• because of the distance between the countries

Multiple Choice

The four planets closest to the Sun are also known as the —

• the gas giants

• jovians

• terrestrial planets

• dwarfs

The Moon and its Magic

• The moon controls the tides on the planet

• Neap Tides occur during a Quarter moon

• Spring tides occur during the full and new moon

• Both kinds of tides are more extreme than normal (i.e. lower than normal or higher then normal)

The Sun, the moon, and the Earth

• Create both Solar and Lunar Eclipses

• Lunar Eclipse is when the Earth is between the sun and the moon

• Solar Eclipse is when the Moon is between the Earth and the sun

Multiple Choice

The moon has a stronger influence on the Earth's tides that the sun because the moon -

• moves much faster relative to the Earth

• is much closer to the Earth

• has more mass than the sun

• is denser than the sun

Multiple Choice

At point 1 high tides are occurring. What must be present in the direction of the dotted line

• The Sun

• The Moon

• a comet

• a planet

Multiple Choice

The highest and lowest tides are known as the spring tides. When do these tides occur?

• Between the half moon and Full moon Phases

• During the new moon and crescent moon phases

• Between the full moon and crescent moon phases

• During the new moon and Full Moon phases

Multiple Choice

Which statement best describes the type of eclipse and the effect experienced on Earth?

• Lunar eclipse; the Moon would block the Sun for an entire day.

• Solar eclipse; the Moon would block the Sun for a short period of time.

• Solar eclipse; the Moon would block the Sun for an entire day.

• Lunar eclipse; the Moon would block the Sun for a short period of time.
