Conglomerate Rocks are formed by the cementing together of particles that eroded from pre-existing rocks. Particles (boulders, rocks, gravel, sand, etc.) are washed or blown away to accumulate somewhere else, and if left in place long enough, can become cemented to form new stone that still shows the character of the original rocks.
