Q

the big bang is a misnomer because..

A

it was neither big nor loud

31
Q

what did the big bang create?

A

stars, planets, solar systems, galaxies and overall universe

32
Q

celestial body that orbits a sun, has a roundish shape due to its gravitational force and has cleared its orbital path

A

planet

33
Q

a star and all of the planets that orbit around it

A

solar system

34
Q

why was pluto declared no longer a planet

A

because its orbital path wasnt cleared

35
Q

a large collection of interstellar material, solar systems and dark matter that is held together by gravity

A

galaxy

36
Q

all of time, space and its contents

A

universe

37
Q

COPERNICUS CAME BEFORE GALILEO

A

YOU GOT THIS GIRL!!!

38
Q

Keplers first law of planetary motion

A

planets orbit the sun in a path called an ellipse

  • the earths diameter is larger at the equator than at the poles
  • caused by the rotation of the earth and the centrifugal force perpendicular to it
39
Q

Keplers 2nd law of planetary motion

A

planets move faster when they are closest to the sun in their orbits (similar to a running track)

40
Q

Keplers 3rd law of planetary motion

A

the further away a planet orbits, the longer it takes to revolve around the sun= longer seasons (also like a running track)

41
Q

How many days does it take to complete the phases of the moon?

A

30 days

42
Q

Name 8 phases of moon

A
  1. new moon
  2. waxing crescent
  3. 1st quarter
  4. waxing gibbous
  5. full moon
  6. waning gibbous
  7. 3rd quarter
  8. waning crescent
43
Q

blue shift

A

stars move towards earth, appear blue, compressing waves and has shorter wavelengths

44
Q

red shift

A

stars move away from the earth, appear red, stretches star light and has longer wavelength

45
Q

nuclear fusion

A
  • process that take place in stars
  • joining of 2 stars
  • making atoms bigger
46
Q

nuclear fission

A
  • process that we use in power plants
  • release of neutrons
  • making atoms smaller
47
Q

similarities between fission and fusion

A

involves nuclei of atoms and releases a lot of energy

48
Q

shorter wavelength

A

higher frequency and higher energy

49
Q

longer wavelength

A

lower frequency, lower energy

50
Q

universe–> planet smallest to biggest

A

planet- solar system- galaxy- universe

51
Q

Spring Tide (vd)

A
  • occur in full/new moons
  • results in maximum tidal range
  • caused by the earth’s gravitational pull
52
Q

Neap Tide

A
  • occur in 1st and 3rd quarter moons
  • results in minimum tidal range
  • caused by the earth’s gravitational pull
53
Q

A wobble around the earth’s axis 1/2 degrees change/18 year period due to the moon’s gravity

A

Nutation

54
