Where is the new crust created and what part of the convection cell is this associated with? a.) it is created at mid-ocean ridges because the upward part of the convection cell causes hot, less dense rocks to rise

b.) it is created at ocean trenches because of the upward part of the convection cell causes hot, less dense rocks to rise

c.) it is created at ocean trenches because of the downward part of the convection cell causes cold, dense rocks to sink

d.) it is created at mid-ocean ridges because of the downward part of the convection cell causes cold, dense rocks to sink
