All of the following are part of sea-floor spreading except a. sea levels rising b. plates moving closer together c. magma filling in gaps in oceanic plates d. trenches forming in the bottom of the ocean floor.

The correct answer should be A. sea levels rising should not be a part of sea-floor spreading.

Hope this helps,

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
