The statement, a hard material
is easily scratched, is false, the answer is letter F. Harder materials have
strong bonding between their neighboring atoms and it takes a greater amount of
energy for them to break apart, even a scratch. The relative hardness of a
mineral can be tested by the Moh’s scale or the mineral hardness. The Moh’s
scale can be characterized by the ability of the mineral to resist scratch
resistance by scratching a harder or softer mineral. It has a scale of 1 to 10
where 1 being the softest and 10 being the hardest.
