What is the Big Bang Theory

The universe formed during a single event in which all matter and energy suddenly expanded from an extremely small point.

100

Name 2 pieces of evidence supporting the Big Bang.

Any 2 of the following:

Measurable expansion of the universe (Red shift of galaxies)

Cosmic microwave background radiation

Relative abundance of hydrogen and helium

100

What powers a star?

Nuclear fusion

100

List the 9 celestial bodies that make up our solar system

Sun, mercury, venus, earth, mars, Jupiter, Saturn, Uranus, Neptune

100

What galaxy is our solar system located in?

The Milky Way Galaxy

100

What is this a picture of?



What is a solar eclipse?

200

About how long ago did the Big Bang occur?

about 13.8 billion years ago

200

Do the majority of stars and galaxies exhibit red shift or blue shift?  Why?

The majority of stars and galaxies exhibit red shift, because they are moving away from Earth.  
200

What stars are the brightest and the hottest?


What are Blue Giants?

200

What is the latitude and longitude for teal/aquamarine location?


What is 105 degrees East and 60 degrees North?

200

Name the three main types of galaxies

Spiral, elliptical, irregular

200

What moon phase will create a solar eclipse?

What is new moon?

300

What were the first two elements to form after the Big Bang?

Hydrogen and Helium

300

Explain why the relative abundance of hydrogen and helium in the universe is consistent with the Big Bang theory

According to the Big Bang Theory, they were the first to form, and so they are the most abundant in the universe.  

300

What property of a star determines whether it ends as a white dwarf, a neutron star or a black hole?   

Its mass

300

Explain what a light-year is

The distance that light travels in a year. 

300

What type (shape) of galaxy is the Milky Way?

Spiral

300

What is this image of?


What is a lunar eclispe?

400

Why do scientists study distant galaxies to gain a better understanding of the beginnings of the universe.

Light from distant galaxies must travel for millions or billions of years before we are able to detect it.  So, when we look at images of galaxies far away, we are actually seeing what these galaxies looked like long ago. 

400

Explain why cosmic microwave background radiation is consistent with the Big Bang Theory

In any explosion, energy is released. Cosmic background radiation is "leftover energy" from the big bang

400

Name a group of stars that is located off from the main sequence

red giants, supergiants, red dwarfs, white dwarfs

400

True or false:  all electromagnetic waves travel at the same speed.

True; they travel at the speed of light

400

Name two main features of a spiral galaxy

A central bulge and spiral arms.

400

What moon phases produce spring tides?

What are new moons and full moons?

500

List both pieces of evidence for the big bang

1. Most galaxies appear to be redshifted

2. cosmic background radiation


500

When our sun dies, what will its next phase be? 

What is a white dwarf?

500

Explain the process that resulted in the formation of our sun

The dust and elements that made up a planetary nebula (space dust left over from exploded stars) began forming into clusters under their own gravity. As these clusters became larger and larger due to their gravitational attractions, they eventually gained enough energy to undergo nuclear fusion.

500

What moon phases cause neap tides?

What are 1st and 3rd Quarter moons?

500

roughly how many stars are in the milky way galaxy?

100-200 billion

500

What is the moon phase?


What is waxing crescent?
