blue shifted
Away, at around 18 km/s.
How close and far something is from you.
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
The moon is moving further away by 1.5cm from the Earth every year.
Away, at around 18 km/s.
Sorry, Andromeda and earth are moving away from each other, not towards each other.

they are moving in all directions away, toward, sideways relative to EarthNearly all galaxies are moving away from the Earth. This is because the universe is expanding.
they look at the sky and say hi to barney

all volcanoes are caused by the earths plates moving toward each other and that is called convergent boundaries.

Due to the doppler effect, objects moving toward us will be slightly more red than what they actually are, and objects moving away will be slightly more blue. Think of it like a siren coming toward you and moving away from you. If it is moving toward you, it will be slightly higher than what it really sounds like. If it is moving away it will have a slightly lower pitch.
The Black Eye Galaxy [See Link] has a redshift of 0.001361, so it is moving away from us. Currently at 24 million light years from Earth
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
Halley's Comet is moving away (in 2010 - when this answer was written), it came close in 1986, it will continue to move away until about 2030 then re-approach and become visible again in mid 2061.
