According to the Moh's Scale of Hardness, the sample mineral that will scratch gypsum but not apatite is MOST LIKELY

• calcite

• quartz

• talc

• topaz

For a science experiment, a student rubs a mineral against a porcelain plate. The students has just performed

• an acid test

• a streak test

• a hardness test

• a fracture test

How are rocks different from minerals?

• Rocks are a pure substance and minerals are all mixtures

• Rocks have no physical or chemical properties similar to minerals

• Rocks are made up of one or more minerals, but minerals are not made up of rocks

• Minerals are made up of at least two rocks, but rocks are not made up of minerals

Which is the best title for this table?

• how to identify a rock

• properties of an element

• properties of a compound

• how to identify a mineral

Under what conditions can igneous rock be transformed into metamorphic rock?

• if layers of sand accumulate over it and harden over a period of time

• if it is exposed at the surface and is weathered over a period of time

• if it is forced deep into Earth, where it melts into magma

• if it is heated and put under pressure for long periods of time

Which best describes to concept of the rock cycle?

• sedimentary rocks may be remelted several times

• rocks move in circles on the Earth as the Earth rotates

• rocks can be moved from place to place on the Earth without changing

• rocks are continually changing, and any type of rock may be transformed into another type by appropriate processes
