@dance36596 can you help me?

OpenStudy (anonymous):

Okay, first, what is a placer deposit?

OpenStudy (anonymous):

placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles.

OpenStudy (anonymous):

Okay, and what's it's relation to a stream bed?

OpenStudy (anonymous):

A stream bed is the channel bottom of a stream, river or creek; the physical confine of the normal water flow.

OpenStudy (anonymous):

You have to figure out their relation to each other, and then find the choice that has the same type of relation. For example, if you have Elephant : peanut, you know the elephant eats the peanut, so a possible match for that could be monkey : banana, so you'd have elephant : peanut :: monkey : banana. Make sense?

OpenStudy (anonymous):

would it be placer deposit : stream bed :: c. nodule : ocean floor

OpenStudy (anonymous):

Does it have the same sort of relation?

OpenStudy (anonymous):

I believe that is the answer, because both are formed in the place they are describing.

OpenStudy (anonymous):

Hope I helped!

OpenStudy (anonymous):

I wouldn't be surface mining : copper, because surface mining is removing, and we are looking at forming.
