Cycle facts for kids
A cycle is a series of events that happen over and over again in the same order. Think of it like a circle where you keep coming back to the start. Cycles are all around us, from the way seasons change to how a bicycle wheel spins. Understanding cycles helps us predict what will happen next and how things work in the world.

What Does "Cycle" Mean?
The word "cycle" can mean different things depending on how it's used. It always involves something repeating.
Repeating Events
One common meaning of cycle is a sequence of events that repeats. For example, the water cycle describes how water moves from the Earth to the sky and back again. The life cycle of an animal or plant shows how it grows, reproduces, and eventually dies, with new life starting the cycle again.
A Type of Vehicle
Sometimes, "cycle" refers to a vehicle. A bicycle is a vehicle with two wheels, and a unicycle has one wheel. These vehicles are called "cycles" because their wheels spin in a circular, repeating motion to move forward.
A Group of Works
In arts and literature, a cycle can be a group of poems, songs, or stories that are connected. They might share a theme, characters, or tell a larger story together. For example, a song cycle is a collection of songs meant to be performed as a single piece.
Examples of Cycles in Nature
Nature is full of amazing cycles that keep our planet running.
The Water Cycle
The water cycle is how water moves around Earth. Water evaporates from oceans and lakes, forms clouds, falls as rain or snow, and then flows back into bodies of water. This process repeats constantly, providing fresh water for living things.
The Seasons Cycle
The Earth's tilt and its orbit around the Sun cause the cycle of seasons. We experience spring, summer, autumn, and winter, each bringing different weather and changes to nature. This cycle repeats every year.
Day and Night Cycle
The rotation of the Earth on its axis creates the cycle of day and night. As our part of the Earth faces the Sun, it's daytime. As it turns away, it becomes night. This cycle happens every 24 hours.
Why Are Cycles Important?
Cycles are important because they bring order and predictability to the world. They help us understand natural processes, plan for the future, and even design machines that work by repeating actions. From the smallest atom to the largest galaxy, cycles are a fundamental part of how the universe operates.
