Geological Time Scale

Question 1:

I think the three major geologic events in the history of the earth were Jurassic, Sirulian, and Precambrian.

Question 2:

There are two eons, which are phanerozoic and precambrian. For  era there is four cenozoic, mesozoic, paleozoic, and proterozoic;  as well as eleven periods and seven epochs.

Question 3:
The difference between eon and era:
Eon: An indefinite and very long period of time, often a period exaggerated for humorous or rhetorical effect.
Era:A long and distinct period of history with a particular feature or characteristic

Question 4: 
Scientist created eons and eras so we'd be able to understand and clearly see the events that ocured in the past.

Hertzsprung-Russell diagram

Why is the Hertzsprung-Russell diagram important to astronomy?

• It explains star evolution, stages, types, color, temperatures, and sizes. It's important for us to know the life cycle so we can prepare for when the star is going to die

What are the two qualities of a star does the HR diagram measure, and how does the diagram do this?

• The HR measures the luminosity and the temperature

Where on the diagram would our sun be found?

• Our sun would be found at 6.000 Kelvins and 1 luminosity
