Geology Part 2-Rocks and Minerals

Rocks are composed of different kinds of

• soilds
• sands
• minerals
• water crystals

According to the Moh's Scale of Mineral 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

• acid test
• streak test
• hardness test
• 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 it is forced deep into Earth, where it melts into magma
• if it is heated and put under pressure for long periods of time
• 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

Which of these BEST describes the 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

Mrs. Smith's class has been studying properties of minerals in science. She has a mineral sample and wants to know which mineral it is. She performed a scratch test using her fingernail, a copper penny, glass, and a steel nail. Which property is Mrs. Smith testing?

• cleavage
• color
• hardness
• luster

Minerals can be identified according to their properties. Alan finds a mineral that is shiny. In which category does Alan's mineral belong? ___________ = shiny nonmetallic = dull, glassy
