The Big Bang
Red Shift Means....
Blue Shift Means...
Things are moving away
Things are moving closer
Use your ESRT, Which Planet has the most Elliptical Orbit?
Mercury because its Eccentricity is the greatest.
Which Element Fuels the Nucleosynthesis of both Average and Massive Stars?
Hydrogen
Which position does a Full Moon Occur?
A. Closest to the Sun (In front of the Earth)
B. Farthest from the Sun (Behind the Earth)
B. Farthest from the Sun (Behind the Earth)
What is the half life of Uranium-235?
713 million years
Cosmic Background Radiation is Evidence that .....
There was a big explosion called The Big Bang and things in space are moving AWAY from each other.
What would make a Planets orbit more elliptical?
Increasing the planets distance from the sun
What's the Difference between the Nucleosynthesis of Average Stars and Massive Stars?
Average Stars only Burn Hydrogen into Helium while Massive Stars Burn the heavier elements such as Silicone into Iron
Which Moon Phases would you see the HIGHEST and LOWEST Tides? What's is that called?
New Moon and Full Moon
Spring Tides
a rock containing carbon-14 ratio measures 1:15 how old is the rock? How many Half lives is that?
22,800 years
4 Half-lives
The Theory that the Universe is Expanding is supported by which TWO pieces of Evidence?
Red Shift and Cosmic Background Radiation
Calculate the Eccentricity (rounded to the nearest thousandth)
- Distance between foci: 3 million km
- Distance of major axis: 4.5 million km
E=0.667
Which Element Fuses into Silicone? What's it's Lifespan?
Oxygen 6 months
What Moon Phases would you see Neap Tides
First Quarter and Last Quarter
300 grams of Carbon-14 after 4 half-lifes how many grams of Carbon would there be left? How much Nitrogen-14?
37.5 grams of Carbon-14
262.5 grams of Nitrogen-14
How can you describe the wavelength of Red Shift and Blue Shift?
Red Shift has a Longer and weaker wavelength
Blue Shift has Shorter but Stronger Wavelengths
How would you find the Length of the Major axis
Distance between the Foci= 15.1cm
Length of Major Axis = X
Eccentricity = 0.206
E=Distance bet. Foci/Length of Major Axis
Since they DO NOT give us the Major Axis we have to divide the Distance bet. Foci/Eccentricity
15.1 /0.206
73.3
Which Element DOES NOT undergo Nucleosynthesis? What happens to it?
FE Iron it the Core Collapses, Supernova
What Moon Phase does a Solar Eclipse Occur During?
New Moon
Why do we use Radioactive Dating to help us calculate the age of fossils/rocks and other material?
Why is Carbon-14 the most helpful?
It is predictable and cyclic and can help us accurately measure age.
Carbon-14 is used for dating organic materials such as fossils
Which types of waves are safe and which are dangerous?
Radio and microwaves are safe
Gama, Ultra Violet and X rays are dangerous
How does the Sun gravity Impact the mercury's orbital velocity?
The closer Mercury is to the Sun the stronger its Gravitational Pull the faster Mercury moves around its orbit.
Which Star has a Higher Luminosity and Lower Temperature than the sun? Rigel or Aldebaran?
Aldebaran
What Moon Phase would you have Not Too much and Not Too Little Light?
First Quarter and Third Quarter
Why wouldn't Carbon-14 be useful in identifying the age of a fossil over 70,000 years old?
It passes its useful dating range and there is not enough carbon-14 for us to be able to be able to accurately measure.
