1: How does sea-floor spreading occur?

A, New materials are being added to the asthenosphere.
B, Earthquakes break apart the ocean floor.
C, Sediments accumulate at the area of spreading.
D, Molten material beneath Earth's crust rises to the surface.

2, Which features form the longest mountain range on Earth?
A, The mid-ocean ridges.
B, The deep-ocean trenches.
C, The Rockies
D, The Andes. < my answer.

3, How does sub-duction change the ocean floor?
A, Subduction causes magma to accumulate on the ocean floor.
B, Subduction causes oceanic crust to break into pieces.
C, Subduction causes the ocean floor to sink into deep ocean trenches.
D, Subduction causes metamorphic rocks to form.

I'm not sure what subduction is, could you explain it to me? I kind of understand sea-floor spreading but am not really sure?? I'm pretty sure I have number 2 right though. Thanks so much for any help you can offer at all, wrong or right answer! Trying is better than not trying haha. Btw, this is a long overdue lesson so I need to get it in soon as possible.

Hi, this is the same person who wrote the post by the way - and I just wanted to make an edit! I think number 1 is C. I also think number 3 is C. I could very well be wrong for both of these however. I just wasn't given much information on the lesson unfortunately. Goodness 6th grade is hard haha!
