1
New cards

What is an HR diagram of what information does it tell you?

It Shows temperature and brightness of stars


2
New cards

How is a star’s color related to its surface temperature?

It shows what temperature is because red equals cooler and blue equals hot

3
New cards

What stage is the longest stage in stellar evolution

Main stage

4
New cards

White dwarfs

Dead average star located on the bottom left of the HR Diagram

5
New cards

Main sequence star

Longest stage All around in a line in the HR diagram

6
New cards

Red giant

Average star losing fuel located in the upper right of the HR diagram

7
New cards

Red super giants

Massive star blazing fuel, located on the upper right

8
New cards

Neutron star

Dead, massive star

9
New cards

Nebula

Cloud of gases

10
New cards

Protostar

When lots of nuclear fusion happen

11
New cards

What is spectroscope?

I tod that shows what elements a star has

12
New cards

What can be determined from a star spectral line?

What elements it has and how it shifts

13
New cards

Explain how a red shift and blue shift can provide information about the movements of a galaxy or a star as seen from earth

Red shift equals moving away blue shift equals moving towards you

14
New cards

What is the Doppler effect? How does it relate to the big?

Change in relative and frequency as it moves closer/further from you, Red shift and blue shifts

15
New cards

first stage

Low mass pro star high mass protype

16
New cards

Second stage

Low mass average star high mass massive star

17
New cards

Stage three

Red giant slow mass high mass red, super giant

18
New cards

Stage four


Low mass planetary nebula, high mass supernova

19
New cards

Stage five

Low mass white dwarf high mass neutron star

20
New cards

What is nuclear fusion and wise important to stellar evolution?

Process were too small atoms, combined to make one bigger atom and in the process a lot of energies released

21
New cards

Core

Hottest part of the sun nuclear fusion happens here

22
New cards

Radiative zone

Energy from core moves outward as radiation

23
New cards

Convicted zone

Hot substances rise in cold substances sink

24
New cards

Photosphere

The visible surface of the sun that gives off light it’s what we actually see from earth

25
New cards

Chromosphere

Thin layer just above the photos sphere visible during a solar eclipse

26
New cards

Corona

The sun’s outer atmosphere only appears during a total eclipse

27
New cards

Where does nuclear fusion occur in the sun?

Core

28
New cards

Sunspots

Dark cooler areas on the sun surface

29
New cards

Solar flares

Sudden burst of energy and radiation

30
New cards

Solar prominences

Large loops arcs of hot plasma, extending from the sun surface

31
New cards

What part of the sun is visible during a total eclipse?

Corona

32
New cards

How long is the sunspot cycle?

11 years

33
New cards

What is convection what layer of the sun would you find the occurring?

Convection is the movement of hot plasma upward cooler plasma downward this would occur in the Conviction zone

34
New cards

What is the name of the model of the solar system that puts earth as the center?

Geocentric model

35
New cards

What is the name of the model of the solar system that puts the sun as the center?

Heliocentric model

36
New cards

List the planets of our solar system in order from the sun out

Mercury Venus earth Mars Jupiter, Saturn, Uranus Neptune

37
New cards

Which planets are gas giants

Jupiter, Saturn, Uranus Neptune

38
New cards

Which planets are the terrorist planets?

Mercury Venus earth Mars

39
New cards

Which planets have a solid surface?

Terrestrial planets

40
New cards

What affects does the sun gravitational pool have on the planets within our solar system?

Pulls on the planets and keeps them in orbit around the sun

41
New cards

Explain the relationship between a plant assistance from the summon in its temperature

Closer planet to the sun hotter generally is the further way the cooler it is

42
New cards

Explain the relationship between a planets distance from the sun and its orbital. Period.

Planets further from the sun have longer orbital. Planet is closer to the sun have a shorter.

43
New cards

Electromagnet spectrum in order

Radio waves microwaves, infared , UV rays, x-rays, gamma rays

44
New cards

When did the Big Bang occur?

13.8 billion years ago

45
New cards

What evidence do we have for the Big Bang occurring?

Doppler effect

46
New cards

What is the most common element stars?

Hydrogen

47
New cards

blank brightness is used to describes a stars brightness as seen from earth

Apparent

48
New cards

Place the following events in chronological order from earliest the most recent following the beginning of the universe, planet and moons nebula galaxy stars

First is nebula second is stars third is galaxies fourth is planet to moons
