Could you tell me stuff about the rock Geode?
Geodes are rock cavities with internal crystal formations, usually made of quartz crystals. Some geodes are completely solid because they are filled with crystals. These are called "nodules". Geodes can form in gas bubbles in igneous rock, or in rounded cavities in sedimentary rock. Most geodes contain clear or white quartz crystals, but purple amethyst crystals are also common.
What are some basic facts about geodes?
Geodes are secondary structures that occur in sedimentary and igneous rocks. Geodes are hallow on the insde. They are spherical to oblate in shape. Most contain clear crystals, though some may contain colored crystals. Geodes are common in the U.S. states of Indiana, Iowa, Missouri, Kentucky and Utah, and the countries Mexico, Brazil, and Namibia.
What color of crystals is most common in a geode?
Geodes come in a large variety of colors depending on the mineral makeup and amount and type of impurities that may be present.
Rock formations called geodes are filled with layers of crystals. which group of words form the complete predicate?
everything from called to crystals is your predicate.
Did you know that geodes are dull balls of igneous or sedimentary rock on the outside but contain beautiful crystals on the inside?
yes
Are geodes filled with anhedral crystals on its walls?

What is the most common color of a geode that you can buy at the store?
The most common color of geode that you can buy at the store would be grey with white. Sometimes dyes are added to "enhance" their beauty. The hollow geodes with crystals usually have white crystals.
What is another name for mineral crystals in cooling magma or lava?
Geodes
Why do the crystals inside geodes vary in color?
Crystals inside geodes will vary in color for a number of reasons. The solutions inside a vug may consist of varying concentrations of different mineral solutions. The mineral crystals that form from these solutions may have a specific color associated with them, such as malachite (green), azurite (blue) or rhodoschrosite (pinkish-red). Minerals that normally have a clear crystalline structure may appear clear or be colored by small amounts of impurities such as iron. In other cases, the minerals inside a vug may be exposed to varying amounts of radiation which can affect their color.
