Rock Hound

Rock Hound

Description: Students will prepare charts and use them to identify various rocks and minerals.  Questions about the rocks or minerals, such as their color, specific gravity, relative hardness, reaction to 3 molar hydrochloric acid, shape, and texture will be asked.  This year will focus more on Igneous rocks.

Should we study anthracite coal as sedimentary or metamorphic?

Anthracite coal should be classified as metamorphic.  It was previously classified by petrologists as sedimentary rock, but a few years back scientific community decided that it has undergone enough pressure to be considered metamorphic - albeit very low grade metamorphic.

May students put the letter/numbers on the chart that corresponds with the rocks in their box?

Students may put any information on the 8 1/2" x 14" chart that they may bring into the event, including the index letter or number that is on a rock specimen.


However, because they will not be allowed to bring their own rock specimens into the competition, it is unclear what value that information might have.

Where can I find example questions for this test?

For some events (including Rock Hound), we have posted copies of old practice tests on this website.  



You should be careful when using these resources, because some questions may no longer match the rules.



Focus this year is Igneous Rock, to what extent should we focus our attention on this type of rock vs others?

It is very important to study all of the rock types as well as the minerals. The official sample list in the rules has 16 rocks and 24 minerals that are permanent fixtures.  This year there are an additional 3 igneous rocks and 3 minerals associated with igneous processes added to the list.  This proportion is relatively representative of the additional focus on igneous rocks.
