a famous baker and invented the raisin theory.
-
All of the above.
Pregunta 2
Pregunta
Galaxies are moving away from us.
Respuesta
- True
- False
Pregunta 3
Pregunta
Hubble believed that the universe is [blank_start]expanding[blank_end] in all directions.
Respuesta
-
expanding
Pregunta 4
Pregunta

-
Energy carried in the form of waves.
-
Rays from the sun.

Used in X-Rays.
-
Used to make food.
Pregunta 5
Pregunta
What does a spectroscope do?
Respuesta
-
Acts like a prism.
-
Separates light into basic component colours.

All of the above.
Pregunta 6
Pregunta
A spectroscope measures wave lengths from the stars spectral lines?
Respuesta
- True
- False
Pregunta 7
Pregunta
When Edwin Hubble was studying the universe he saw the spectral lines from the purple side of the spectrum.
Respuesta
- True
- False
Pregunta 8
Pregunta
[blank_start]Red shift[blank_end] is when lights [blank_start]wave lengths[blank_end] become [blank_start]longer[blank_end]. That means that the object is [blank_start]receding[blank_end] away from us. Meaning that distant [blank_start]galaxies[blank_end] are moving [blank_start]away[blank_end] from us. When Edwin Hubble saw this, he discovered that the Universe was [blank_start]expanding[blank_end]. [blank_start]Cosmological Red shift[blank_end] is when lights wavelengths are constantly being lengthened. This is the main theory for how the Universe was born.
Respuesta
-
Red shift
-

-
longer
-
receding
-
galaxies
-
away
-
expanding
-
Cosmological Red shift
Pregunta 9
Pregunta
What is the Big Bang theory?
Respuesta
-
A show.
-
When space itself began, from a really tiny piece of space suddenly expanded into immense size in a very short time.
-
When all the planets were formed.
-
None of the above.
Pregunta 10
Pregunta
Cosmic background radiation is:
Respuesta
-
Radiation from microwaves.
-
A type of wavelength.
-
noise in space.
-
radiation left over from the Big Bang. When the universe was created it produced heat in the form of microwave radiation.
Pregunta 11
Pregunta
COBE stands for: Cosmic Background Explorer.
Respuesta
- True
- False
Pregunta 12
Pregunta
One of the strongest pieces of evidence to support the big bang theory is [blank_start]Cosmic Background Explorer[blank_end]. A team of Scientists moped the universe by using a satellite they sent up into space. they mapped the [blank_start]background radiation[blank_end]. Red areas indicate hotter places. Blue areas indicate places that have had time to cool.
Respuesta
-
background radiation
-
Microwave radiation
-
UV radiation
-

Pregunta 13
Pregunta
Wilkinson Microwave Antistropy Probe was sent up into space to make better predictions then the COBE.
Respuesta
- True
- False
Pregunta 14
Pregunta
Galaxies are clouds made out of dust and gas.
Respuesta
- True
- False
Pregunta 15
Pregunta

Spiral Galxies are shaped like a pin wheel from above and from the side it looks like a plate with an orange in it. it contains mostly [blank_start]new[blank_end] [blank_start]stars[blank_end].
Respuesta
-
Spiral
-
Elliptical
-
Irregular
