Our Place in Space

The theory that describes how the universe began is called 

• The Nebular Theory
• Heliocentric Theory
• The Big Bang Theory
• Geocentric Theory

Two major pieces of evidence that support the Big Bang Theory are:

• Nebulas & Nuclear Fission
• Redshift & Expansion
• Hubble and the ISS
• X-Rays & Gamma Rays

This is the theory that describes how solar systems are created.

• Nebular Theory
• Big Bang Theory
• Heliocentric Theory
• Geocentric Theory

Planets form through the process of "accretion".  This is when...

• Rocks collide and grow bigger and bigger.
• Two hydrogen atoms fuse to create helium.
• 99.9% of the mass from a nebula becomes a star.
• None of these.

Objects with more mass... 

• Have fewer molecules.
• Have stronger gravitational pull.
• Move more slowly.
• None of these.

What process happens in the core of all stars?

• accretion
• nuclear fusion
• erosion
• deposition

Our sun will run out of basic hydrogen fuel in about 5 billion years.  When this happens it will become...

• supernova
• black hole
• a red giant
• blue super giant

A large mass star begins to die.  The next step might be a _____________. 

• planetary nebula
• white dwarf
• red giant
• supernova

A white dwarf is the final stage for _________ mass stars like our Sun.

• small/medium
• large
• super massive
• none of these

The path a star takes during its life cycle depends solely on its _____.
