Pebble. Stone. Boulder. The simple rock goes by many names. By definition, rocks are solid masses of metals, minerals, and crystals called aggregates. The study of rocks is known as petrology, and it is a central component of the earth science, geology.
Rocks can be placed in three different classifications. In Latin, the word igneus meant "fire," and igneous rocks are those formed by fire - specifically, by the heat of lava and magma. Sedimentary rock, on the other hand, is created when tiny particles on the earth's surface are pressed together to become a whole. Finally, metamorphic rock is any type of rock that has been changed in form by the addition of heat and pressure.
Today, and throughout history, humans have used rocks for many things. Rocks could be used as weapons, crafted into tools such as hammers, shaped into blocks for the building of structures, and certain precious stones could be cut and polished to create a variety of jewelry. Coal was burned as a source of heat. Certain rocks were heated to extract precious metals such as silver and gold.

1. Begin by drawing a bumpy, curved line. This line will form the top of a rock.
2. Enclose the figure of the rock using a second irregular, curved line.
3. Begin to draw another, smaller rock using a curved line extending from the first.
4. Finish enclosing the figure of the second rock using a curved line. Allow the line to curve back around on itself, thus enclosing a third small rock. Enclose the form of a forth rock nearby.
5. Extend a curved line from the pile of rocks. This begins the outline of yet another rock.
6. Finish enclosing the figure of the previous rock by drawing two more small rocks at its base. For each small rock, use a curved line.
7. Using a curved line, enclose the irregular form of another rock to one side of the picture.
8. Give your rocks some ground to stand on. Extend a horizon line from each side of the rock pile. Beneath and around the rocks, draw curved lines of various lengths, giving the ground texture.
9. Near the beach blanket, draw more curved lines indicating sand. On top of the sand, draw a circle. Stripe the circle using curved lines. You have just drawn a beach ball. Then, detail the umbrella by drawing long, curved lines from the top of the shaft to the points of the "U" shaped lines. Finally, enclose fluffy clouds in the sky using connected, curved lines.
