Sound, earthquakes, and waves in water are mechanical waves because they require a physical ______________________ to transport energy.
Disturbance
Electromagnetic field
Location
Medium
Sound, waves are all propagation of energy. Transport of this energy require a physical medium. Thus option D is correct.
What is mechanical waves?Mechanical waves are a form of energy transfer by oscillation of matter and they require a medium to propagate. Sound wave is a longitudinal wave which is only passing through a medium of air. Air disturbance causes these sound waves.
Longitudinal waves are those where the direction of oscillation of matter is along the direction of propagation. Electromagnetic waves does not require a medium to travel.
Waves in water originates from the pressure difference in water earthquakes is caused by seismic waves which are transverse waves, where the oscillation of matter is perpendicular to the direction of propagation.
Hence, sound, earthquakes, and waves in water are mechanical waves because they require a physical medium.

include quartzite and marble
tend to split along their bands
form from crystallized magma
Non-foliated rocks include quartzite and marble. Therefore, option (B) is correct.
What are the non-foliated rocks?Nonfoliated rocks less foliated texture because they commonly lack platy minerals like micas. They often result from regional metamorphism. Examples include quartzite, marble, hornfel, greenstone, and anthracite.
Marble is low to high-grade metamorphosed dolostone or limestone both of which are carbonate rocks, They are made of dolomite grains or interlocked calcite. Marble is very often carved in the artwork of palaces.
Quartzite is quartz sandstone that is medium to high-grade metamorphism. It is composed of interlocking grains of quartz and can be distinguished from sandstone because individual grains do not fall off during the rock is rubbed. Original sedimentary structures in quartzite will remain visible.
