What evidence do astronomers have to support the Big Bang theory? galaxies are disappearing
galaxies are coming together in a big crunch
galaxies are staying still
galaxies are moving away from each other

d.galaxies are moving away from each other

Explanation:

"a" is incorrect because galaxies don't die per-say

"b" the big crunch is about how the universe might end

"c" is also incorrect because everything in our galaxy stays moving and if it were to stop moving it would shrink and if it were to speed up, it would get bigger (the explanation as to why "d" is the correct answer)

good luck :)

hopefully, this helps

**please let me know if this was wrong**

have a nice day !!

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
