The Earth Gallery has a multitude of display cases of rocks, minerals, and gems. Here is one of them.
But first, volcanic forces, and the different kinds of volcanoes, are examined.
Different volcanoes generate different forces and effects during eruptions or active volcanoes, like lava or pyroclastic flows. Some examples are on display here as well.
Here we have the first of the volcano types, lava domes. We'll pick up here tomorrow.
