Image that says Cycles.

Animation of three arrows forming the dish (cupboard, table, sink, cupboard) cycle.  Please have someone assist you with this. Understanding cycles is important if you want to understand your home planet. You can use some everyday activity to understand the concept of a cycle. For example, you take dishes out of the cupboard, put them on the table, use them to hold your food during dinner, carry them to the sink or dishwasher, wash them, and carry them back to the cupboard again. And you--or someone--must do this every day and every meal of every day. The dishes are part of a cycle. They move from the cupboard to the table to the sink back to the cupboard. This cycle could be called the dish cycle.

Earth also has a number of cycles. And like the example above, scientists identify the cycle by the material that is put through the repetition or cycle. Two of the most important of Earth's cycles are the rock cycle and the water cycle.
