ESPS Astronomy PartA

Brayan Hernandez Esquivel

QuestionAnswer
How old is the universe? The Universe is 14 billion years old.
What event began the universe? The event that started the universe is the Big Bang
What are the visible forms of light? Visible forms of light are infrared and UV light
What is a light year? Distance light travels in one year.
Explain Red Shift. How is blue shift different? Red shift is objects or planets moving farther away from us. Blue shift is the opposite, objects/planets move towards us
How is the universe moving and what shift of light do you see? The universe is expanding and we see red shift in that movement.
On the EM Spectrum different colors happen because of what? Different colors happen because of the wavelength
How does temperature relate to density? It is a indirect relation. Higher temperature means lower mass.
What are two ways you can increase gravity? Increase the mass or shorten the distance
What are CMB's and why are they important? CMB shows the amount of temperature and density areas had to form solar systems. It is important because it is a big piece of evidence for the Big Bang Theory
Stars and galaxies in the inverse start in what type of temperature, density and gravity regions? They start in low temperature with high density and high gravity regions.
Describe what the different colors in the CMB represent and how they are related to temperature and density. The different colors represent different areas of density. The temperature and density have an indirect relation.
Describe the relationship between wavelength, frequency and energy. Longer wavelength is lower frequency and lower energy.
Describe and Explain how the Universe got from the Big Bang to how it looks today (make sure to include density, temperature and star and galaxy formation). The temperature started to cool down and which caused more density, this is how our solar system was formed and how it is now.
Formula for Eccentricity E=d/L
What is the minimum eccentricity an ellipse can have? The minimum eccentricity an ellipse can have is 0.
What is the name of the geometric figure with 0 eccentricity? The figure is called a circle.
What does the process of nuclear fusion produce? The process of nuclear fusion creates energy and it is released.
What is the ratio of hydrogen to helium in the early universe? The ratio of hydrogen to helium is 3H:1He
The universe was primarily made up of what elements? Hydrogen Helium and oxygen
What is the temperature of the CMB right now? The temperature of the CMB right now is 27K
What causes different colors in visible light? The wavelength and frequency cause different colors.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
