What's one of the key characteristics of sedimentary rocks? How are these types of rock formed?
 
sedimentary rocks formed due to weathering action of water, wind and frost on existing rocks generally uniform, fine grained and compact

And how do these bits of existing rock collect before being turned into a sedimentary rock? What is the chief feature of their appearance?

Hint: It's OK to look at pictures of rocks on the internet. ;)
 
by look by touch
it's hard difficult to notice the difference in pictures u can try that
