  1. Rock On! The Never –Ending Cycle of Changing Rocks By Martha Bakula

  2. Cycles • To understand the rock cycle, it is important to understand what a cycle is. A cycle is when things happen over and over in the same order like sunrise, daytime, sunset and nighttime.

  3. The rock cycle is a never-ending cycle of rocks changing over time. Volcanoes throw out magma (melted rock) which hardens into rock. Weather wears away the hardened rock into bits of tiny rock pieces. Rivers carry the rock bits to oceans. The tiny pieces settle on the bottom of the ocean and pile up and form new rocks. Heat inside the earth melts some of these rocks. Then volcanoes throw them out as magma and the never-ending rock cycle begins again.
