100

Compounds that consist of oxygen and another element, and usually appear as metals.

Oxides

100

Minerals composed of 2 or more elements.

Compounds

100

Finding this by rubbing a mineral against a rough surface is a more reliable way to find its color.

Streak

100

A geologist who identifies and studies mineral samples.

Mineralogists

100

An inorganic, crystalline, naturally occurring solid having a definite chemical compound.


Mineral

200

The most common class of minerals in the Earth’s crust, made of silicon and oxygen.

Silicates
200

These are made of only one element and are usually found in placer deposits.

Native Minerals

200

The main defining characteristic in a mineral’s crystal classification. (DAILY DOUBLE)

Shape

200

The most common method for obtaining minerals and ores.

Mining

200

You should look for these when conducting an acid test on a mineral sample.

Gas Bubbles

300

These minerals fizz when in contact with hydrochloric acid.

Carbonates

300

True or False: All minerals are composed of 2 or more elements.

False

300

The amount and quality of the light reflected from a mineral’s surface.

Luster

300

The system used to rate a mineral‘s relative hardness.

Mohs Scale

300

One of the best conductors of electricity, but easily tarnishes.

Silver

400

Minerals that are made of sulfur and another element; one example is pyrite. (DAILY DOUBLE)

Sulfides

400

Rocks and seawater are both these, formations of physically combined elements

Mixtures

400

The breaking or chipping of minerals along definite surfaces with varying quality.

Cleavage

400

The unit of measurement used to describe the mass of minerals such as diamonds.

 Carat

400

Minerals such as obsidian break into smooth, shell-shaped chips, showing this kind of fracture.

Chonchoidal

500

Minerals that are more commonly known as salts, such as road salt and table salt.

Halides

500

Important sources of minerals, such as cinnabar containing mercury, are called these.

Ores

500

The ratio of the density of a mineral specimen to the density of water at 4 degrees Celsius.

Specific Gravity

500

The process by which a crystal grows by accumulating more particles and bonds.

Accretion

500

A deep vertical shaft of rock produced by volcanic activity in which diamonds are frequently found.
