The following contains the properties of four different samples:
Sample W is hard and composed of two materials
Sample X is soft and composed of one material
Sample Y is hard and composed of one material
Sample Z is hard and composed of three materials
Which of the following is true of the objects?
Samples X and Z are minerals, and
samples W and Y are rocks
Samples X and Y are minerals, and
samples W and Z are rocks.
Samples W and Z are minerals, and
samples X and Y are rocks.
Samples W and Y are minerals, and
samples X and Z are rocks.
Listed below are six minerals along with their hardness as determined by the Mohs hardness scale:
Alabaster 2.0
Boracite 7.5
Creedite 4.0
Ekanite 5.5
Moissanite 9.3
Spectrolite 6.0
Using the list, which minerals will scratch Ekanite?
Boracite, Spectrolite, and Moissanite
Alabaster and Creedite
Boracite and Moissanite
Alabaster, Moissante, and Creedite
A pocket of melted rock, or magma, has
formed deep below the surface of Earth. After the pocket of magma slowly cools,
what does the magma become?
intrusive igneous rock
extrusive igneous rock
sedimentary rock
metamorphic rock
Limestone is a type of rock that can form in two
ways. It can either form from the accumulation of
shell and skeletal debris of ocean organisms, or it
can form when calcium compounds precipitate
out of ocean water and become cemented
together. Under which classification does
limestone belong?
igneous rock
silica rock
metamorphic rock
sedimentary rock
This picture shows a granite rock that was
sculpted into a statue. Granite is often used for
decoration and sculpting because the large
crystal formations are very beautiful. The large
crystals are formed when magma cools slowly.
marble
sedimentary
igneous
metamorphic
