The answer is C. Hope this helped
Igneous Rocks
At diverging plate boundaries, convection currents bring hot magma to the surface. Sometimes, magma that gets pushed up at plate boundaries cools before it gets there. It fills in cracks and voids in the bedrock
Metamorphic Rocks
Hot magma pushes itself to the surface at both divergent plate boundaries and convergent plate boundaries. This magma comes in contact with rocks as it rises to the surface.

Answer:
velocity = 7.30 m/sec
23 m depth wave will feel bottom
Explanation:
given data
wavelength = 46 meters
wave period = 6.3 second
to find out
velocity and At what water depth will a deep water wave begin to feel bottom
solution
we get here velocity that is express as
velocity =
.............1
velocity =
velocity = 7.30 m/sec
and
wave base =
× wavelength .................2
wave base =
× 46
wave base = 23 m
here water depth more than 23 m will producer will circular wave less than elliptical wave
so 23 m depth wave will feel bottom
