5What is a Geode?
A geode is a hollow, rounded rock where the inside cavity is lined with
crystals. A geode begins as a bubble in volcanic rock or a hollow in
sedimentary rock. Eventually, the outer shell hardens as a rock. Minerals
begin to form inside, and over thousands of years, many layers of crystals
appear inside the geode.
6What is the difference between a rock and a mineral?
Minerals are the building blocks of rocks. Minerals are crystalline solids
that have specific physical properties and a narrowly defined chemical
composition. Rocks are formed from minerals.
