Rock Collecting: A Hobby that's "Hard" to Resist

By: K.Bader

Rock collecting is a fascinating hobby for kids and adults
alike. While rocks are common, cheap, and found everywhere, the
variety is huge. Collected rocks can be displayed in many ways,
from rock gardens to neatly kept showcases, making rock
collecting a versatile hobby.

When rock collecting, you will soon find out that rocks can be
categorized as one of three types. A sedimentary rock formed
when sediments, such as sand or silt, were pressed together
under their own weight or the weight of water, and eventually
became solid. An igneous rock is one that was formed by volcanic
activity. The third type of rock for rock collecting is the
metamorphic rock, which is like a sedimentary rock which has
been changed through intense heat and pressure.

Another type of rock collecting is collecting minerals, gems,
and crystals. Pure minerals are not technically the same thing
as rocks, but they fit well in rock collections. Minerals
include things like pyrite, also known as fool's gold, and
quartzite, which looks almost like a diamond.

For some people, rock collecting consists of saving a pretty
rock from different places they visit and keeping it as a
souvenir. If these rocks are large, they can be used to outline
the driveway or start a rock garden. If they are small, they can
line a windowsill. Label them with a fine point marker if
desired. Include the date and location the rock was found.

The souvenir type of rock collecting does not require much
scientific investigation, but identifying rocks and minerals
does. The different types of rock can sometimes be
differentiated easily. For instance, sedimentary rocks often
look like particles glued together. Sandstone is a common
example of this. They also sometimes have visible flat layers.
Metamorphic rocks, on the other hand, sometimes have layers, but
those layers have been bent so that they are no longer laying
flat across the rock.

When rock collecting, the igneous rocks make some of the most
exciting finds. Obsidian is an igneous rock that looks like a
broken piece of black glass. It is shiny and hard, and was used
to make arrowheads in the past by the native Americans. Pumice
is another interesting igneous rock which is porous, making it
so light that it will float. This stone is used for cleaning and
rubbing calluses off people's feet.

Keep in mind when rock collecting that different regions of the
world have different types of rocks. In the American Midwest,
for instance, there are many sedimentary stones, but metamorphic
and igneous rocks are less common. In the Appalachians, on the
other hand, you can find metamorphic rocks such as gneiss and
schist. Wherever you live, though, you are sure to find rock
collecting a hobby that's hard to resist!
