Because magma cooled enough to enter a solid state. Because sediments compacted over many years into a hardened solid. Because dissolved minerals were left behind by moving water. Because it fell from space. I'm sure there are other reasons.

What is a Rock
The best way to define a rock is to say that it is an indefinite mixture of naturally occurring substances, mainly minerals. Its composition may vary in containment of minerals and organic substances, and are never exact. They can range from tiny microscopic grains of minerals or organic substances to coarse agglomerates of different minerals, where the individual minerals are easily discernible. They may range in size from tiny pebbles to huge mountains. Rocks make up the earth’s crust. Many rocks are not solid -- such as magma, soil, and clay. In general, the only people interested in rocks are geologists and paleontologist who are interested in the scientific nature and dating of the rocks. Different mineral deposits can be found in related rock formations, providing use by estimating what minerals rock formations may contain.
The term "rock collection" is usually misused for "mineral collection". Although a few people collect rocks, the amount of people collecting minerals is much greater.
