Answer the following question given this paragraph: Minerals can form various shapes. Polygons are pictured below ( Figure below ). The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones. Q: The shapes of minerals form as they are broken along what planes? Choices: - parallel planes - sedimentary planes - calcium planes - cleavage planes A:
(Answer)
cleavage planes

Ques:Answer the following question given this paragraph: Total internal reflection occurs when light goes from a slow (high index of refraction) medium to a fast (low index of refraction) medium. With total internal reflection, light refracts so much it actually refracts back into the first medium. This is how fiber optic cables work: no light leaves the wire. Q: When does internal reflection occur? Choices: - when light goes from a slow medium to another slow medium - when light goes from a fast medium to a slow - when light goes from a fast medium to another fast medium - when light goes from a slow medium to a fast A:

Ans:when light goes from a slow medium to a fast
