When animals leave their parents to establish their own lives, if they encounter the parents again in the wild, do they recognise each other and does this influence their behaviour? via /r/askscience


When animals leave their parents to establish their own lives, if they encounter the parents again in the wild, do they recognise each other and does this influence their behaviour?

I'm thinking of, for example, eagles that have been nurtured by their parents for many months before finally leave the nest to establish their own territory. Surely a bond has been created there, that could influence future interactions between these animals?

If you put a giant mirror on the floor of the earth and make a photo from a satelite, what would you be able to see? via /r/askscience


If you put a giant mirror on the floor of the earth and make a photo from a satelite, what would you be able to see?

In my class this came up in a discussion and we were unsure what the result would be.

  1. The mirror would be blue, as it reflects the color from the sky
  2. The mirror would be black as it reflects the "color" from outer space
  3. The mirror would be white as the refraction from the atmosohere gets canceled

Edit 1: Thanks for your answers. My conclusion of this would be, that the image of the mirror would be blue (if there is no sun in the frame)
